  <p>In certain circumstances described in the definition of the

  A <a href="the-select-element.html#placeholder-label-option">placeholder label option</a> does not represent an actual

  <p>The <dfn id="attr-option-value" title="attr-option-value"><code>value</code></dfn>

  <div class="impl">

  <p>The <dfn id="concept-option-selectedness" title="concept-option-selectedness">selectedness</dfn>

  <p>The <dfn id="dom-option-form" title="dom-option-form"><code>form</code></dfn> IDL

  <p>Several constructors are provided for creating

When invoked as constructors,
  these must return a new <code><a href="#htmloptionelement">HTMLOptionElement</a></code> object (a new
  <code><a href="#the-option-element">option</a></code> element). If the <var title="">text</var>
  argument is present, the new object must have as its only child a

  the <var title="">value</var> argument is present, the new object
  must have a <code title="attr-option-value"><a href="#attr-option-value">value</a></code> attribute
  set with the value of the argument as its value. If the <var title="">defaultSelected</var> argument is present and true, the new
  object must have a <code title="attr-option-selected"><a href="#attr-option-selected">selected</a></code> attribute set with no
  value. If the <var title="">selected</var> argument is present and
  true, the new object must have its <a href="#concept-option-selectedness" title="concept-option-selectedness">selectedness</a> set to true;
  otherwise the fourth argument is absent or false, and the <a href="#concept-option-selectedness" title="concept-option-selectedness">selectedness</a> must be set

  a story, or a transition to another topic within a section of a
  reference book.</p>

  <div class="example">

   <p>The following fictional extract from a project manual shows two
   sections that use the <code><a href="#the-hr-element">hr</a></code> element to separate topics
   within the section.</p>

   <pre>&lt;section&gt;
 &lt;h1&gt;Communication&lt;/h1&gt;
 &lt;p&gt;There are various methods of communication. This section
 covers a few of the important ones used by the project.&lt;/p&gt;
 <strong><a href="#the-hr-element">&lt;hr&gt;</a></strong>
 &lt;p&gt;Communication stones seem to come in pairs and have mysterious
 properties:&lt;/p&gt;
 &lt;ul&gt;
  &lt;li&gt;They can transfer thoughts in two directions once activated
  if used alone.&lt;/li&gt;
  &lt;li&gt;If used with another device, they can transfer one's
  consciousness to another body.&lt;/li&gt;
  &lt;li&gt;If both stones are used with another device, the
  consciousnesses switch bodies.&lt;/li&gt;
 &lt;/ul&gt;
 <strong><a href="#the-hr-element">&lt;hr&gt;</a></strong>
 &lt;p&gt;Radios use the electromagnetic spectrum in the meter range and
 longer.&lt;/p&gt;
 <strong><a href="#the-hr-element">&lt;hr&gt;</a></strong>
 &lt;p&gt;Signal flares use the electromagnetic spectrum in the
 nanometer range.&lt;/p&gt;
&lt;/section&gt;
&lt;section&gt;
 &lt;h1&gt;Food&lt;/h1&gt;
 &lt;p&gt;All food at the project is rationed:&lt;/p&gt;
 &lt;dl&gt;
  &lt;dt&gt;Potatoes&lt;/dt&gt;
  &lt;dd&gt;Two per day&lt;/dd&gt;
  &lt;dt&gt;Soup&lt;/dt&gt;
  &lt;dd&gt;One bowl per day&lt;/dd&gt;

   <p>There is no need for an <code><a href="#the-hr-element">hr</a></code> element between the
   sections themselves, since the <code><a href="the-section-element.html#the-section-element">section</a></code> elements and
   the <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code> elements imply thematic changes themselves.</p>

   <p>The following extract from <cite>Pandora's Star</cite> by Peter
   F. Hamilton shows two paragraphs that precede a scene change and
   the paragraph that follows it. The scene change, represented in the
   printed book by a gap containing a solitary centered star between
   the second and third paragraphs, is here represented using the
   <code><a href="#the-hr-element">hr</a></code> element.</p>

   <pre lang="en-GB">&lt;p&gt;Dudley was ninety-two, in his second life, and fast approaching
time for another rejuvenation. Despite his body having the physical
age of a standard fifty-year-old, the prospect of a long degrading
campaign within academia was one he regarded with dread. For a
supposedly advanced civilization, the Intersolar Commonwealth could be
appallingly backward at times, not to mention cruel.&lt;/p&gt;
&lt;p&gt;&lt;i&gt;Maybe it won't be that bad&lt;/i&gt;, he told himself. The lie was
comforting enough to get him through the rest of the night's
shift.&lt;/p&gt;
<strong><a href="#the-hr-element">&lt;hr&gt;</a></strong>
&lt;p&gt;The Carlton AllLander drove Dudley home just after dawn. Like the
astronomer, the vehicle was old and worn, but perfectly capable of
doing its job. It had a cheap diesel engine, common enough on a
semi-frontier world like Gralmond, although its drive array was a
thoroughly modern photoneural processor. With its high suspension and
deep-tread tyres it could plough along the dirt track to the
observatory in all weather and seasons, including the metre-deep snow
of Gralmond's winters.&lt;/p&gt;</pre>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-small-element">small</a></code> element <a href="rendering.html#represents">represents</a> side
  comments such as small print.</p>

  <p class="note">Small print typically features disclaimers, caveats,
  legal restrictions, or copyrights. Small print is also sometimes
  used for attribution, or for satisfying licensing requirements.</p>

  <p class="note">The <code><a href="#the-small-element">small</a></code> element does not
  "de-emphasize" or lower the importance of text emphasized by the
  <code><a href="the-em-element.html#the-em-element">em</a></code> element or marked as important with the
  <code><a href="the-strong-element.html#the-strong-element">strong</a></code> element. To mark text as not emphasized or
  important, simply do not mark it up with the <code><a href="the-em-element.html#the-em-element">em</a></code> or
  <code><a href="the-strong-element.html#the-strong-element">strong</a></code> elements respectively.</p>

  <p>The <code><a href="#the-small-element">small</a></code> element should not be used for extended
  spans of text, such as multiple paragraphs, lists, or sections of
  text. It is only intended for short runs of text. The text of a page
  listing terms of use, for instance, would not be a suitable
  candidate for the <code><a href="#the-small-element">small</a></code> element: in such a case, the
  text is not a side comment, it is the main content of the page.</p>

  <div class="example">

   <p>In this example, the <code><a href="#the-small-element">small</a></code> element is used to
   indicate that value-added tax is not included in a price of a hotel
   room:</p>

   <pre class="example">&lt;dl&gt;
 &lt;dt&gt;Single room
 &lt;dd&gt;199 &#8364; &lt;small&gt;breakfast included, VAT not included&lt;/small&gt;
 &lt;dt&gt;Double room
 &lt;dd&gt;239 &#8364; &lt;small&gt;breakfast included, VAT not included&lt;/small&gt;
&lt;/dl&gt;</pre>

  </div>

  <div class="example">

   <p>In this second example, the <code><a href="#the-small-element">small</a></code> element is used
   for a side comment in an article.</p>

   <pre>&lt;p&gt;Example Corp today announced record profits for the
second quarter &lt;small&gt;(Full Disclosure: Foo News is a subsidiary of
Example Corp)&lt;/small&gt;, leading to speculation about a third quarter
merger with Demo Group.&lt;/p&gt;</pre>

   <p>This is distinct from a sidebar, which might be multiple
   paragraphs long and is removed from the main flow of text. In the
   following example, we see a sidebar from the same article. This
   sidebar also has small print, indicating the source of the
   information in the sidebar.</p>

   <pre>&lt;aside&gt;
 &lt;h1&gt;Example Corp&lt;/h1&gt;
 &lt;p&gt;This company mostly creates small software and Web
 sites.&lt;/p&gt;
 &lt;p&gt;The Example Corp company mission is "To provide entertainment
 and news on a sample basis".&lt;/p&gt;
 &lt;p&gt;&lt;small&gt;Information obtained from &lt;a
 href="http://example.com/about.html"&gt;example.com&lt;/a&gt; home
 page.&lt;/small&gt;&lt;/p&gt;
&lt;/aside&gt;</pre>

  </div>

  <div class="example">

   <p>In this last example, the <code><a href="#the-small-element">small</a></code> element is marked
   as being <em>important</em> small print.</p>

   <pre>&lt;p&gt;&lt;strong&gt;&lt;small&gt;Continued use of this service will result in a kiss.&lt;/small&gt;&lt;/strong&gt;&lt;/p&gt;</pre>

  (typically keyboard input, although it may also be used to represent
  other input, such as voice commands).</p>

  <p>When the <code><a href="#the-kbd-element">kbd</a></code> element is nested inside a
  <code><a href="the-samp-element.html#the-samp-element">samp</a></code> element, it represents the input as it was echoed
  by the system.</p>

  <p>When the <code><a href="#the-kbd-element">kbd</a></code> element <em>contains</em> a
  <code><a href="the-samp-element.html#the-samp-element">samp</a></code> element, it represents input based on system
  output, for example invoking a menu item.</p>

  <p>When the <code><a href="#the-kbd-element">kbd</a></code> element is nested inside another
  <code><a href="#the-kbd-element">kbd</a></code> element, it represents an actual key or other
  single unit of input as appropriate for the input mechanism.</p>

  <div class="example">
   <p>Here the <code><a href="#the-kbd-element">kbd</a></code> element is used to indicate keys to press:</p>
   <pre>&lt;p&gt;To make George eat an apple, press &lt;kbd&gt;&lt;kbd&gt;Shift&lt;/kbd&gt;+&lt;kbd&gt;F3&lt;/kbd&gt;&lt;/kbd&gt;&lt;/p&gt;</pre>

   <p>In this second example, the user is told to pick a particular
   menu item. The outer <code><a href="#the-kbd-element">kbd</a></code> element marks up a block of
   input, with the inner <code><a href="#the-kbd-element">kbd</a></code> elements representing each
   individual step of the input, and the <code><a href="the-samp-element.html#the-samp-element">samp</a></code> elements
   inside them indicating that the steps are input based on something
   being displayed by the system, in this case menu labels:</p>

   <pre>&lt;p&gt;To make George eat an apple, select
    &lt;kbd&gt;&lt;kbd&gt;&lt;samp&gt;File&lt;/samp&gt;&lt;/kbd&gt;|&lt;kbd&gt;&lt;samp&gt;Eat Apple...&lt;/samp&gt;&lt;/kbd&gt;&lt;/kbd&gt;
&lt;/p&gt;</pre>

   <p>Such precision isn't necessary; the following is equally fine:</p>

   <pre>&lt;p&gt;To make George eat an apple, select &lt;kbd&gt;File | Eat Apple...&lt;/kbd&gt;&lt;/p&gt;</pre>

  <div class="example">

   <p>This example shows a <code><a href="#the-fieldset-element">fieldset</a></code> element being used to
   group a set of related controls:</p>

   <pre>&lt;fieldset&gt;
 &lt;legend&gt;Display&lt;/legend&gt;
 &lt;p&gt;&lt;label&gt;&lt;input type=radio name=c value=0 checked&gt; Black on White&lt;/label&gt;
 &lt;p&gt;&lt;label&gt;&lt;input type=radio name=c value=1&gt; White on Black&lt;/label&gt;
 &lt;p&gt;&lt;label&gt;&lt;input type=checkbox name=g&gt; Use grayscale&lt;/label&gt;
 &lt;p&gt;&lt;label&gt;Enhance contrast &lt;input type=range name=e list=contrast min=0 max=100 value=0 step=1&gt;&lt;/label&gt;
 &lt;datalist id=contrast&gt;
  &lt;option label=Normal value=0&gt;
  &lt;option label=Maximum value=100&gt;
 &lt;/datalist&gt;
&lt;/fieldset&gt;</pre>

  </div>

  <div class="example">

   <p>The following snippet shows a fieldset with a checkbox in the
   legend that controls whether or not the fieldset is enabled. The
   contents of the fieldset consist of two required text fields and an
   optional year/month control.</p>

   <pre>&lt;fieldset name="clubfields" disabled&gt;
 &lt;legend&gt; &lt;label&gt;
  &lt;input type=checkbox name=club onchange="form.clubfields.disabled = !checked"&gt;
  Use Club Card
 &lt;/label&gt; &lt;/legend&gt;
 &lt;p&gt;&lt;label&gt;Name on card: &lt;input name=clubname required&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Card number: &lt;input name=clubnum required pattern="[-0-9]+"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Expiry date: &lt;input name=clubexp type=month&gt;&lt;/label&gt;&lt;/p&gt;
&lt;/fieldset&gt;</pre>

  </div>

  <div class="example">

   <p>You can also nest <code><a href="#the-fieldset-element">fieldset</a></code> elements. Here is an
   example expanding on the previous one that does so:</p>

   <pre>&lt;fieldset name="clubfields" disabled&gt;
 &lt;legend&gt; &lt;label&gt;
  &lt;input type=checkbox name=club onchange="form.clubfields.disabled = !checked"&gt;
  Use Club Card
 &lt;/label&gt; &lt;/legend&gt;
 &lt;p&gt;&lt;label&gt;Name on card: &lt;input name=clubname required&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset name="numfields"&gt;
  &lt;legend&gt; &lt;label&gt;
   &lt;input type=radio checked name=clubtype onchange="form.numfields.disabled = !checked"&gt;
   My card has numbers on it
  &lt;/label&gt; &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt;Card number: &lt;input name=clubnum required pattern="[-0-9]+"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset name="letfields" disabled&gt;
  &lt;legend&gt; &lt;label&gt;
   &lt;input type=radio name=clubtype onchange="form.letfields.disabled = !checked"&gt;
   My card has letters on it
  &lt;/label&gt; &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt;Card code: &lt;input name=clublet required pattern="[A-Za-z]+"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
&lt;/fieldset&gt;</pre>

   <p>In this example, if the outer "Use Club Card" checkbox is not
   checked, everything inside the outer <code><a href="#the-fieldset-element">fieldset</a></code>,
   including the two radio buttons in the legends of the two nested
   <code><a href="#the-fieldset-element">fieldset</a></code>s, will be disabled. However, if the checkbox
   is checked, then the radio buttons will both be enabled and will
   let you select which of the two inner <code><a href="#the-fieldset-element">fieldset</a></code>s is to
   be enabled.</p>

  <a href="content-models.html#flow-content-1">flow content</a>, optionally with a caption, that is
  self-contained and is typically referenced as a single unit from the
  main flow of the document.</p>

  <p>The element can thus be used to annotate illustrations, diagrams,
  photos, code listings, etc, that are referred to from the main
  content of the document, but that could, without affecting the flow
  of the document, be moved away from that primary content, e.g. to
  the side of the page, to dedicated pages, or to an appendix.</p>

  <p>The <span class="impl">first</span> <code><a href="the-figcaption-element.html#the-figcaption-element">figcaption</a></code>
  element child of the element, if any, represents the caption of the
  <code><a href="#the-figure-element">figure</a></code> element's contents. If there is no child
  <code><a href="the-figcaption-element.html#the-figcaption-element">figcaption</a></code> element, then there is no caption.</p>

  <div class="example">

   <p>This example shows the <code><a href="#the-figure-element">figure</a></code> element to mark up a
   code listing.</p>

 &lt;pre&gt;&lt;code&gt;interface PrimaryCore {
 boolean verifyDataLine();
 void sendData(in sequence&amp;lt;byte&gt; data);
 void initSelfDestruct();
}&lt;/code&gt;&lt;/pre&gt;
&lt;/figure&gt;
&lt;p&gt;The API is designed to use UTF-8.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>Here we see a <code><a href="#the-figure-element">figure</a></code> element to mark up a

   a figure, as well as an image and a video that are.</p>

   <pre>&lt;h2&gt;Malinko's comics&lt;/h2&gt;

&lt;p&gt;This case centered on some sort of "intellectual property"
infringement related to a comic (see Exhibit A). The suit started
after a trailer ending with these words:

&lt;blockquote&gt;
 &lt;img src="promblem-packed-action.png" alt="ROUGH COPY! Promblem-Packed Action!"&gt;
&lt;/blockquote&gt;

&lt;p&gt;...was aired. A lawyer, armed with a Bigger Notebook, launched a
preemptive strike using snowballs. A complete copy of the trailer is
included with Exhibit B.

 &lt;img src="ex-a.png" alt="Two squiggles on a dirty piece of paper."&gt;
 &lt;figcaption&gt;Exhibit A. The alleged &lt;cite&gt;rough copy&lt;/cite&gt; comic.&lt;/figcaption&gt;

 &lt;figcaption&gt;Exhibit B. The &lt;cite&gt;Rough Copy&lt;/cite&gt; trailer.&lt;/figcaption&gt;

&lt;p&gt;The case was resolved out of court.</pre>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-p-element">p</a></code> element <a href="rendering.html#represents">represents</a> a
  <a href="content-models.html#paragraph">paragraph</a>.</p>

  <p class="note">While paragraphs are usually represented in visual
  media by blocks of text that are physically separated from adjacent
  blocks through blank lines, a style sheet or user agent would be
  equally justified in presenting paragraph breaks in a different
  manner, for instance using inline pilcrows (&#182;).</p>

  <div class="example">
   <p>The following examples are conforming HTML fragments:</p>
   <pre>&lt;p&gt;The little kitten gently seated himself on a piece of
carpet. Later in his life, this would be referred to as the time the
cat sat on the mat.&lt;/p&gt;</pre>
   <pre>&lt;fieldset&gt;
 &lt;legend&gt;Personal information&lt;/legend&gt;
 &lt;p&gt;
   &lt;label&gt;Name: &lt;input name="n"&gt;&lt;/label&gt;
   &lt;label&gt;&lt;input name="anon" type="checkbox"&gt; Hide from other users&lt;/label&gt;
 &lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Address: &lt;textarea name="a"&gt;&lt;/textarea&gt;&lt;/label&gt;&lt;/p&gt;
&lt;/fieldset&gt;</pre>
   <pre>&lt;p&gt;There was once an example from Femley,&lt;br&gt;
Whose markup was of dubious quality.&lt;br&gt;
The validator complained,&lt;br&gt;
So the author was pained,&lt;br&gt;
To move the error from the markup to the rhyming.&lt;/p&gt;</pre>
  </div>

  <p>The <code><a href="#the-p-element">p</a></code> element should not be used when a more
  specific element is more appropriate.</p>

  <div class="example">

   <p>The following example is technically correct:</p>

<pre>&lt;section&gt;
 &lt;!-- ... --&gt;
 &lt;p&gt;Last modified: 2001-04-23&lt;/p&gt;
 &lt;p&gt;Author: fred@example.com&lt;/p&gt;
&lt;/section&gt;</pre>

   <p>However, it would be better marked-up as:</p>

<pre>&lt;section&gt;
 &lt;!-- ... --&gt;
 &lt;footer&gt;Last modified: 2001-04-23&lt;/footer&gt;
 &lt;address&gt;Author: fred@example.com&lt;/address&gt;
&lt;/section&gt;</pre>

   <p>Or:</p>

<pre>&lt;section&gt;
 &lt;!-- ... --&gt;
 &lt;footer&gt;
  &lt;p&gt;Last modified: 2001-04-23&lt;/p&gt;
  &lt;address&gt;Author: fred@example.com&lt;/address&gt;
 &lt;/footer&gt;
&lt;/section&gt;</pre>

  </div>

  <div class="note">

   <p>List elements (in particular, <code><a href="the-ol-element.html#the-ol-element">ol</a></code> and
   <code><a href="the-ul-element.html#the-ul-element">ul</a></code> elements) cannot be children of <code><a href="#the-p-element">p</a></code>
   elements. When a sentence contains a bulleted list, therefore, one
   might wonder how it should be marked up.</p>

   <div class="example">
    <p>For instance, this fantastic sentence has bullets relating to</p>
    <ul><li>wizards,
     </li><li>faster-than-light travel, and
     </li><li>telepathy,
    </li></ul><p>and is further discussed below.</p>
   </div>

   <p>The solution is to realise that a <i><a href="content-models.html#paragraph">paragraph</a></i>, in HTML
   terms, is not a logical concept, but a structural one. In the
   fantastic example above, there are actually <em>five</em> <a href="content-models.html#paragraph" title="paragraph">paragraphs</a> as defined by this
   speciication: one before the list, one for each bullet, and one
   after the list.</p>

   <div class="example">

    <p>The markup for the above example could therefore be:</p>

    <pre>&lt;p&gt;For instance, this fantastic sentence has bullets relating to&lt;/p&gt;
&lt;ul&gt;
 &lt;li&gt;wizards,
 &lt;li&gt;faster-than-light travel, and
 &lt;li&gt;telepathy,
&lt;/ul&gt;
&lt;p&gt;and is further discussed below.&lt;/p&gt;</pre>

   </div>

   <p>Authors wishing to conveniently style such "logical" paragraphs
   consisting of multiple "structural" paragraphs can use the
   <code><a href="the-div-element.html#the-div-element">div</a></code> element instead of the <code><a href="#the-p-element">p</a></code> element.</p>

   <div class="example">

    <p>Thus for instance the above example could become the following:</p>

    <pre>&lt;div&gt;For instance, this fantastic sentence has bullets relating to
&lt;ul&gt;
 &lt;li&gt;wizards,
 &lt;li&gt;faster-than-light travel, and
 &lt;li&gt;telepathy,
&lt;/ul&gt;
and is further discussed below.&lt;/div&gt;</pre>

    <p>This example still has five structural paragraphs, but now the
    author can style just the <code><a href="the-div-element.html#the-div-element">div</a></code> instead of having to
    consider each part of the example separately.</p>

  <div class="example">

   <p>The collection of metadata in a <code><a href="#the-head-element">head</a></code> element can be
   large or small. Here is an example of a very short one:</p>

   <pre>&lt;!doctype html&gt;

 &lt;head&gt;
  &lt;title&gt;A document with a short head&lt;/title&gt;
 &lt;/head&gt;

&lt;HTML&gt;
 &lt;HEAD&gt;
  &lt;META CHARSET="UTF-8"&gt;
  &lt;BASE HREF="http://www.example.com/"&gt;
  &lt;TITLE&gt;An application with a long head&lt;/TITLE&gt;

  <p class="note">The <code><a href="the-title-element.html#the-title-element">title</a></code> element is a required child
  in most situations, but when a higher-level protocol provides title
  information, e.g. in the Subject line of an e-mail when HTML is used
  as an e-mail authoring format, the <code><a href="the-title-element.html#the-title-element">title</a></code> element can be
  omitted.</p>

  <code><a href="the-article-element.html#the-article-element">article</a></code> element instead of the <code><a href="#the-section-element">section</a></code>
  element when it would make sense to syndicate the contents of the
  element.</p>

  <p class="note" id="use-div-for-wrappers">The <code><a href="#the-section-element">section</a></code>
  element is not a generic container element. When an element is
  needed only for styling purposes or as a convenience for scripting,
  authors are encouraged to use the <code><a href="the-div-element.html#the-div-element">div</a></code> element instead.
  A general rule is that the <code><a href="#the-section-element">section</a></code> element is
  appropriate only if the element's contents would be listed
  explicitly in the document's <a href="headings-and-sections.html#outline">outline</a>.</p>

  <div class="example">

   <p>In the following example, we see an article (part of a larger
   Web page) about apples, containing two short sections.</p>

   <pre>&lt;article&gt;
 &lt;hgroup&gt;
  &lt;h1&gt;Apples&lt;/h1&gt;
  &lt;h2&gt;Tasty, delicious fruit!&lt;/h2&gt;
 &lt;/hgroup&gt;
 &lt;p&gt;The apple is the pomaceous fruit of the apple tree.&lt;/p&gt;
 &lt;section&gt;
  &lt;h1&gt;Red Delicious&lt;/h1&gt;
  &lt;p&gt;These bright red apples are the most common found in many
  supermarkets.&lt;/p&gt;
 &lt;/section&gt;
 &lt;section&gt;
  &lt;h1&gt;Granny Smith&lt;/h1&gt;
  &lt;p&gt;These juicy, green apples make a great filling for
  apple pies.&lt;/p&gt;
 &lt;/section&gt;
&lt;/article&gt;</pre>

   <p>Notice how the use of <code><a href="#the-section-element">section</a></code> means that the author
   can use <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code> elements throughout, without having to
   worry about whether a particular section is at the top level, the
   second level, the third level, and so on.</p>

  </div>

  <div class="example">

   <p>Here is a graduation programme with two sections, one for the
   list of people graduating, and one for the description of the
   ceremony.</p>

   <p>In this example, a book author has marked up some sections as
   chapters and some as appendices, and uses CSS to style the headers
   in these two classes of section differently. The whole book is
   wrapped in an <code><a href="the-article-element.html#the-article-element">article</a></code> element as part of an even
   larger document containing other books.</p>

   <pre>&lt;article class="book"&gt;
 &lt;style&gt;
  section { border: double medium; margin: 2em; }
  section.chapter h1 { font: 2em Roboto, Helvetica Neue, sans-serif; }
  section.appendix h1 { font: small-caps 2em Roboto, Helvetica Neue, sans-serif; }
 &lt;/style&gt;
 &lt;header&gt;
  &lt;hgroup&gt;
   &lt;h1&gt;My Book&lt;/h1&gt;
   &lt;h2&gt;A sample with not much content&lt;/h2&gt;
  &lt;/hgroup&gt;
  &lt;p&gt;&lt;small&gt;Published by Dummy Publicorp Ltd.&lt;/small&gt;&lt;/p&gt;
 &lt;/header&gt;
 &lt;section class="chapter"&gt;
  &lt;h1&gt;My First Chapter&lt;/h1&gt;
  &lt;p&gt;This is the first of my chapters. It doesn't say much.&lt;/p&gt;
  &lt;p&gt;But it has two paragraphs!&lt;/p&gt;
 &lt;/section&gt;
 &lt;section class="chapter"&gt;
  &lt;h1&gt;It Continutes: The Second Chapter&lt;/h1&gt;
  &lt;p&gt;Bla dee bla, dee bla dee bla. Boom.&lt;/p&gt;
 &lt;/section&gt;
 &lt;section class="chapter"&gt;
  &lt;h1&gt;Chapter Three: A Further Example&lt;/h1&gt;
  &lt;p&gt;It's not like a battle between brightness and earthtones would go
  unnoticed.&lt;/p&gt;
  &lt;p&gt;But it might ruin my story.&lt;/p&gt;
 &lt;/section&gt;
 &lt;section class="appendix"&gt;
  &lt;h1&gt;Appendix A: Overview of Examples&lt;/h1&gt;
  &lt;p&gt;These are demonstrations.&lt;/p&gt;
 &lt;/section&gt;
 &lt;section class="appendix"&gt;
  &lt;h1&gt;Appendix B: Some Closing Remarks&lt;/h1&gt;
  &lt;p&gt;Hopefully this long example shows that you &lt;em&gt;can&lt;/em&gt; style
  sections, so long as they are used to indicate actual sections.&lt;/p&gt;
 &lt;/section&gt;

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-article-element">article</a></code> element <a href="rendering.html#represents">represents</a> a
  self-contained composition in a document, page, application, or site
  and that is, in principle, independently distributable or reusable,
  e.g. in syndication. This could be a forum post, a magazine or
  newspaper article, a blog entry, a user-submitted comment, an
  interactive widget or gadget, or any other independent item of
  content.</p>

  <p>When <code><a href="#the-article-element">article</a></code> elements are nested, the inner
  <code><a href="#the-article-element">article</a></code> elements represent articles that are in
  principle related to the contents of the outer article. For
  instance, a blog entry on a site that accepts user-submitted
  comments could represent the comments as <code><a href="#the-article-element">article</a></code>
  elements nested within the <code><a href="#the-article-element">article</a></code> element for the blog
  entry.</p>

  <p>Author information associated with an <code><a href="#the-article-element">article</a></code>
  element (q.v. the <code><a href="the-address-element.html#the-address-element">address</a></code> element) does not apply to
  nested <code><a href="#the-article-element">article</a></code> elements.</p>

  <p class="note">When used specifically with content to be
  redistributed in syndication, the <code><a href="#the-article-element">article</a></code> element is
  similar in purpose to the <code title="">entry</code> element in
  Atom. <a href="references.html#refsATOM">[ATOM]</a>

   <p>Notice the use of <code><a href="the-footer-element.html#the-footer-element">footer</a></code> to give the information
   for each comment (such as who wrote it and when): the
   <code><a href="the-footer-element.html#the-footer-element">footer</a></code> element <em>can</em> appear at the start of its
   section when appropriate, such as in this case. (Using
   <code><a href="the-header-element.html#the-header-element">header</a></code> in this case wouldn't be wrong either; it's
   mostly a matter of authoring preference.)</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-blockquote-element">blockquote</a></code> element <a href="rendering.html#represents">represents</a> a
  section that is quoted from another source.</p>

  <p>Content inside a <code><a href="#the-blockquote-element">blockquote</a></code> must be quoted from
  another source, whose address, if it has one, may be cited in the
  <dfn id="attr-blockquote-cite" title="attr-blockquote-cite"><code>cite</code></dfn>
  attribute.</p>

  <p>If the <code title="attr-blockquote-cite"><a href="#attr-blockquote-cite">cite</a></code> attribute
  is present, it must be a <a href="urls.html#valid-url-potentially-surrounded-by-spaces">valid URL potentially surrounded by
  spaces</a>. <span class="impl">To obtain the corresponding
  citation link, the value of the attribute must be <a href="urls.html#resolve-a-url" title="resolve a url">resolved</a> relative to the element. User
  agents should allow users to follow such citation links.</span></p>

  <p>The content of a <code><a href="#the-blockquote-element">blockquote</a></code> may be abbreviated or
  may have context added in the conventional manner for the text's
  language.</p>

  <div class="example">

   <p>For example, in English this is traditionally done using square
   brackets. Consider a page with the sentence "Fred ate the cracker.
   He then said he liked apples and fish."; it could be quoted as
   follows:</p>

   <pre>&lt;blockquote&gt;
 &lt;p&gt;[Fred] then said he liked [...] fish.&lt;/p&gt;
&lt;/blockquote&gt;</pre>

  </div>

  <p>Attribution for the quotation, if any, must be placed outside the
  <code><a href="#the-blockquote-element">blockquote</a></code> element.</p> <!-- Eventually someone is
  going to ask about quotes that are self-attributing, e.g. someone
  quoting an e-mail with full headers... -->

  <div class="example">

   <p>For example, here the attribution is given in a paragraph after
   the quote:</p>

   <pre>&lt;blockquote&gt;
 &lt;p&gt;I contend that we are both atheists. I just believe in one fewer
 god than you do. When you understand why you dismiss all the other
 possible gods, you will understand why I dismiss yours.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;&#8212; Stephen Roberts&lt;/p&gt;</pre>

   <p>The other examples below show other ways of showing
   attribution.</p>

  </div>

  <div class="impl">

  <p>The <dfn id="dom-quote-cite" title="dom-quote-cite"><code>cite</code></dfn> IDL
  attribute must <a href="common-dom-interfaces.html#reflect">reflect</a> the element's <code title="">cite</code> content attribute.</p>

  </div>

  <div class="example">

   <p>Here a <code><a href="#the-blockquote-element">blockquote</a></code> element is used in conjunction
   with a <code><a href="the-figure-element.html#the-figure-element">figure</a></code> element and its <code><a href="the-figcaption-element.html#the-figcaption-element">figcaption</a></code>
   to clearly relate a quote to its attribution (which is not part of
   the quote and therefore doesn't belong inside the
   <code><a href="#the-blockquote-element">blockquote</a></code> itself):</p>

   <pre>&lt;figure&gt;
 &lt;blockquote&gt;
  &lt;p&gt;The truth may be puzzling. It may take some work to grapple with.
  It may be counterintuitive. It may contradict deeply held
  prejudices. It may not be consonant with what we desperately want to
  be true. But our preferences do not determine what's true. We have a
  method, and that method helps us to reach not absolute truth, only
  asymptotic approaches to the truth &#8212; never there, just closer
  and closer, always finding vast new oceans of undiscovered
  possibilities. Cleverly designed experiments are the key.&lt;/p&gt;

  <p>An <code><a href="#the-rp-element">rp</a></code> element <span class="impl">that is a child of
  a <code><a href="the-ruby-element.html#the-ruby-element">ruby</a></code> element</span> <a href="rendering.html#represents">represents</a>
  nothing<span class="impl"> and its contents must be
  ignored</span>. <span class="impl">An <code><a href="#the-rp-element">rp</a></code> element whose
  parent element is not a <code><a href="the-ruby-element.html#the-ruby-element">ruby</a></code> element
  <a href="rendering.html#represents">represents</a> its children.</span></p>

  <div class="example">

   <p>The example above, in which each ideograph in the text <span lang="ja" title="">&#28450;&#23383;</span> is annotated with its
   phonetic reading, could be expanded to use <code><a href="#the-rp-element">rp</a></code> so that in
   legacy user agents the readings are in parentheses:</p>

   <pre lang="ja">...
&lt;ruby&gt;&#28450;&lt;rp&gt; (&lt;/rp&gt;&lt;rt&gt;&#12363;&#12435;&lt;/rt&gt;&lt;rp&gt;) &lt;/rp&gt;&#23383;&lt;rp&gt; (&lt;/rp&gt;&lt;rt&gt;&#12376;&lt;/rt&gt;&lt;rp&gt;) &lt;/rp&gt;&lt;/ruby&gt;
...</pre>

   <p>In conforming user agents the rendering would be as above, but
   in user agents that do not support ruby, the rendering would
   be:</p>

   <pre lang="ja">... &#28450; (&#12363;&#12435;) &#23383; (&#12376;) ...</pre>

  <p class="note">The <code><a href="#the-details-element">details</a></code> element is not appropriate
  for footnotes. Please see <a href="links.html#footnotes">the section on
  footnotes</a> for details on how to mark up footnotes.</p>

  <p>The <span class="impl">first</span> <code><a href="the-summary-element.html#the-summary-element">summary</a></code> element
  child of the element, if any, <a href="rendering.html#represents">represents</a> the summary or
  legend of the details. <span class="impl">If there is no child
  <code><a href="the-summary-element.html#the-summary-element">summary</a></code> element, the user agent should provide its own
  legend (e.g. "Details").</span></p>

  <p>The rest of the element's contents <a href="rendering.html#represents">represents</a> the
  additional information or controls.</p>

  <p>The <dfn id="attr-details-open" title="attr-details-open"><code>open</code></dfn>
  content attribute is a <a href="common-microsyntaxes.html#boolean-attribute">boolean attribute</a>. If present,
  it indicates that both the summary and the additional information is
  to be shown to the user. If the attribute is absent, only the
  summary is to be shown.</p>

  <div class="impl">

  <p>When the element is created, if the attribute is absent, the
  additional information should be hidden; if the attribute is
  present, that information should be shown. Subsequently, if the
  attribute is removed, then the information should be hidden; if the
  attribute is added, the information should be shown.</p>

  <p>The user agent should allow the user to request that the
  additional information be shown or hidden. To honor a request for
  the details to be shown, the user agent must set the <code title="attr-details-open"><a href="#attr-details-open">open</a></code> attribute on the element to
  the value <code title="">open</code>. To honor a request for the
  information to be hidden, the user agent must remove the <code title="attr-details-open"><a href="#attr-details-open">open</a></code> attribute from the
  element.</p>

  <p>The <dfn id="dom-details-open" title="dom-details-open"><code>open</code></dfn> IDL
  attribute must <a href="common-dom-interfaces.html#reflect">reflect</a> the <code title="attr-details-open"><a href="#attr-details-open">open</a></code> content attribute.</p>

  </div>

  <div class="example">

   <p>The following example shows the <code><a href="#the-details-element">details</a></code> element
   being used to hide technical details in a progress report.</p>

   <pre>&lt;section class="progress window"&gt;
 &lt;h1&gt;Copying "Really Achieving Your Childhood Dreams"&lt;/h1&gt;
 &lt;details&gt;
  &lt;summary&gt;Copying... &lt;progress max="375505392" value="97543282"&gt;&lt;/progress&gt; 25%&lt;/summary&gt;
  &lt;dl&gt;
   &lt;dt&gt;Transfer rate:&lt;/dt&gt; &lt;dd&gt;452KB/s&lt;/dd&gt;
   &lt;dt&gt;Local filename:&lt;/dt&gt; &lt;dd&gt;/home/rpausch/raycd.m4v&lt;/dd&gt;
   &lt;dt&gt;Remote filename:&lt;/dt&gt; &lt;dd&gt;/var/www/lectures/raycd.m4v&lt;/dd&gt;
   &lt;dt&gt;Duration:&lt;/dt&gt; &lt;dd&gt;01:16:27&lt;/dd&gt;
   &lt;dt&gt;Color profile:&lt;/dt&gt; &lt;dd&gt;SD (6-1-6)&lt;/dd&gt;
   &lt;dt&gt;Dimensions:&lt;/dt&gt; &lt;dd&gt;320&#215;240&lt;/dd&gt;
  &lt;/dl&gt;
 &lt;/details&gt;
&lt;/section&gt;</pre>

  </div>

  <div class="example">

   <p>The following shows how a <code><a href="#the-details-element">details</a></code> element can be
   used to hide some controls by default:</p>

   <pre>&lt;details&gt;
 &lt;summary&gt;&lt;label for=fn&gt;Name &amp; Extension:&lt;/label&gt;&lt;/summary&gt;
 &lt;p&gt;&lt;input type=text id=fn name=fn value="Pillar Magazine.pdf"&gt;
 &lt;p&gt;&lt;label&gt;&lt;input type=checkbox name=ext checked&gt; Hide extension&lt;/label&gt;
&lt;/details&gt;</pre>

   <p>One could use this in conjunction with other <code><a href="#the-details-element">details</a></code>
   in a list to allow the user to collapse a set of fields down to a
   small set of headings, with the ability to open each one.</p>

   <p class="details-example"><img alt="" height="611" src="images/sample-details-1.png" width="345"><img alt="" height="666" src="images/sample-details-2.png" width="345"></p>

   <p>In these examples, the summary really just summarises what the
   controls can change, and not the actual values, which is less than
   ideal.</p>

  </div>

  <div class="example">

   <p>Because the <code title="attr-details-open"><a href="#attr-details-open">open</a></code>
   attribute is added and removed automatically as the user interacts
   with the control, it can be used in CSS to style the element
   differently based on its state. Here, a stylesheet is used to
   animate the color of the summary when the element is opened or
   closed:</p>

   <pre>&lt;style&gt;
 details &gt; summary { transition: color 1s; color: black; }
 details[open] &gt; summary { color: red; }
&lt;/style&gt;
&lt;details&gt;
 &lt;summary&gt;Automated Status: Operational&lt;/summary&gt;
 &lt;p&gt;Velocity: 12m/s&lt;/p&gt;
 &lt;p&gt;Direction: North&lt;/p&gt;
&lt;/details&gt;</pre>

  of a page that consists of content that is tangentially related to
  the content around the <code><a href="#the-aside-element">aside</a></code> element, and which could
  be considered separate from that content. Such sections are often
  represented as sidebars in printed typography.</p>

  <p>The element can be used for typographical effects like pull
  quotes or sidebars, for advertising, for groups of <code><a href="the-nav-element.html#the-nav-element">nav</a></code>
  elements, and for other content that is considered separate from the
  main content of the page.</p>

  <p class="note">It's not appropriate to use the <code><a href="#the-aside-element">aside</a></code>
  element just for parentheticals, since those are part of the main
  flow of the document.</p>

&lt;q&gt;I love my job. People ask me what I do for fun when I'm not at
work. But I'm paid to do my hobby, so I never know what to
answer. Some people wonder what they would do if they didn't have to
work... but I know what I would do, because I was unemployed for a
year, and I filled that time doing exactly what I do now.&lt;/q&gt;&lt;/p&gt;

  <p>The string to use as the document's title is given by the <code title="dom-document-title"><a href="dom.html#document.title">document.title</a></code> IDL attribute.</p>

  <div class="impl">

  <p>User agents should use the document's title when referring to the
  document in their user interface. When the contents of a
  <code><a href="#the-title-element">title</a></code> element are used in this way, <a href="global-attributes.html#the-directionality">the
  directionality</a> of that <code><a href="#the-title-element">title</a></code> element should be
  used to set the directionality of the document's title in the user
  interface.</p>

  <!-- v2 idea: DOM Range APIs to expose the textarea/input edited
  value (ack martijnw) -->

  <p>The <code><a href="the-input-element.html#the-input-element">input</a></code> and <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> elements define
  the following members in their DOM interfaces for handling their
  selection:</p>

  <pre class="idl extract">  void <span title="dom-textarea/input-select">select</span>();
           attribute unsigned long <span title="dom-textarea/input-selectionStart">selectionStart</span>;
           attribute unsigned long <span title="dom-textarea/input-selectionEnd">selectionEnd</span>;
           attribute DOMString <span title="dom-textarea/input-selectionDirection">selectionDirection</span>;

  void <span title="dom-textarea/input-setSelectionRange">setSelectionRange</span>(unsigned long start, unsigned long end, optional DOMString direction = "preserve");</pre>
  <!-- v2: also add textLength? it seems to be widely used -->



  <p>These methods and attributes expose and control the selection of
  <code><a href="the-input-element.html#the-input-element">input</a></code> and <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> text fields.</p>

  <dl class="domintro"><dt><var title="">element</var> . <code title="dom-textarea/input-select">select</code>()</dt>

   <dd>

    <p>Selects everything in the text field.</p>

   </dd>

   <dt><var title="">element</var> . <code title="dom-textarea/input-selecionStart">selectionStart</code> [ = <var title="">value</var> ]</dt>

   <dd>

    <p>Returns the offset to the start of the selection.</p>

    <p>Can be set, to change the start of the selection.</p>

   </dd>

   <dt><var title="">element</var> . <code title="dom-textarea/input-selecionEnd">selectionEnd</code> [ = <var title="">value</var> ]</dt>

   <dd>

    <p>Returns the offset to the end of the selection.</p>

    <p>Can be set, to change the end of the selection.</p>

   </dd>

   <dt><var title="">element</var> . <code title="dom-textarea/input-selecionDirection">selectionDirection</code> [ = <var title="">value</var> ]</dt>

   <dd>

    <p>Returns the current direction of the selection.</p>

    <p>Can be set, to change the direction of the selection.</p>

    <p>The possible values are "<code title="">forward</code>", "<code title="">backward</code>", and "<code title="">none</code>".</p>

   </dd>

   <dt><var title="">element</var> . <code title="dom-textarea/input-setSelectionRange">setSelectionRange</code>(<var title="">start</var>, <var title="">end</var> [, <var title="">direction</var>] )</dt>

   <dd>

    <p>Changes the selection to cover the given substring in the given direction. If the direction is omitted, it will be reset to be the platform default (none or forward).</p>

   </dd>


  </dl><p>All elements to which this API applies have either a selection or
  a text entry cursor position at all times (even for elements that
  are not <a href="rendering.html#being-rendered">being rendered</a>). User agents should follow
  platform conventions to determine their initial state.</p>

  

  <p>Characters with no visible rendering, such as U+200D ZERO WIDTH
  JOINER, still count as characters. Thus, for instance, the selection
  can include just an invisible character, and the text insertion
  cursor can be placed to one side or another of such a character.</p>

  <div class="example">

   <p>To obtain the currently selected text, the following JavaScript
   suffices:</p>

   <pre>var selectionText = control.value.substring(control.selectionStart, control.selectionEnd);</pre>

   <p>...where <var title="">control</var> is the <code><a href="the-input-element.html#the-input-element">input</a></code>
   or <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> element.</p>

  </div>

  <div class="example">

   <p>To add some text at the start of a text control, while
   maintaining the text selection, the three attributes must be
   preserved:</p>

   <pre>var oldStart = control.selectionStart;
var oldEnd = control.selectionEnd;
var oldDirection = control.selectionDirection;
var prefix = "http://";
control.value = prefix + control.value;
control.setSelectionRange(oldStart + prefix.length, oldEnd + prefix.length, oldDirection);</pre>

   <p>...where <var title="">control</var> is the <code><a href="the-input-element.html#the-input-element">input</a></code>
   or <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> element.</p>

  in the attribute names, to reduce the risk of clashes. Where it
  makes sense, library authors are also encouraged to make the exact
  name used in the attribute names customizable, so that libraries
  whose authors unknowingly picked the same name can be used on the
  same page, and so that multiple versions of a particular library can
  be used on the same page even when those versions are not mutually
  compatible.</p>

  <div class="example">

   <p>For example, a library called "DoQuery" could use attribute
   names like <code title="">data-doquery-range</code>, and a library
   called "jJo" could use attributes names like <code title="">data-jjo-range</code>. The jJo library could also provide
   an API to set which prefix to use (e.g. <code title="">J.setDataPrefix('j2')</code>, making the attributes have
   names like <code title="">data-j2-range</code>).</p>

  text that is to be isolated from its surroundings for the purposes
  of bidirectional text formatting. <a href="references.html#refsBIDI">[BIDI]</a></p>

  <p class="note">The <code title="attr-dir"><a href="global-attributes.html#the-dir-attribute">dir</a></code> global
  attribute defaults to <code title="attr-dir-auto"><a href="global-attributes.html#attr-dir-auto">auto</a></code> on
  this element (it never inherits from the parent element like with
  other elements).</p>

  <div class="impl">

  <p>For the purposes of applying the bidirectional algorithm to the
  contents of a <code><a href="#the-bdi-element">bdi</a></code> element, user agents must treat the
  element as a paragraph-level container.</p>

  <p>For the purposes of applying the bidirectional algorithm to the
  paragraph-level container that a <code><a href="#the-bdi-element">bdi</a></code> element finds
  itself within, the <code><a href="#the-bdi-element">bdi</a></code> element must be treated like a
  U+FFFC OBJECT REPLACEMENT CHARACTER (in the same manner that an
  image or other inline object is handled).</p>

  <p>The requirements on handling the <code><a href="#the-bdi-element">bdi</a></code> element for the
  bidirectional algorithm may be implemented indirectly through the
  style layer. For example, an HTML+CSS user agent could implement
  these requirements by implementing the CSS 'unicode-bidi' property.
  <a href="references.html#refsCSS">[CSS]</a></p>

  </div>

  <div class="example">

   <p>This element is especially useful when embedding user-generated
   content with an unknown directionality.</p>

   <p>In this example, usernames are shown along with the number of
   posts that the user has submitted. If the <code><a href="#the-bdi-element">bdi</a></code> element
   were not used, the username of the Arabic user would end up
   confusing the text (the bidirectional algorithm would put the colon
   and the number "3" next to the word "User" rather than next to the
   word "posts").</p>

   <pre>&lt;ul&gt;
 &lt;li&gt;User &lt;bdi&gt;jcranmer&lt;/bdi&gt;: 12 posts.
 &lt;li&gt;User &lt;bdi&gt;hober&lt;/bdi&gt;: 5 posts.
 &lt;li&gt;User &lt;bdi&gt;<bdo dir="rtl">&#1573;&#1610;&#1575;&#1606;</bdo>&lt;/bdi&gt;: 3 posts.

  resources</a> for <a href="media-elements.html#media-element" title="media element">media
  elements</a>. It does not <a href="rendering.html#represents" title="represents">represent</a> anything on its own.</p>

  <p>The <dfn id="attr-source-src" title="attr-source-src"><code>src</code></dfn> attribute
  gives the address of the <a href="media-elements.html#media-resource">media resource</a>. The value must
  be a <a href="urls.html#valid-non-empty-url-potentially-surrounded-by-spaces">valid non-empty URL potentially surrounded by
  spaces</a>. This attribute must be present.</p>

  <p class="note">Dynamically modifying a <code><a href="#the-source-element">source</a></code> element
  and its attribute when the element is already inserted in a
  <code><a href="the-video-element.html#the-video-element">video</a></code> or <code><a href="the-audio-element.html#the-audio-element">audio</a></code> element will have no
  effect. To change what is playing, just use the <code title="attr-media-src"><a href="media-elements.html#attr-media-src">src</a></code> attribute on the <a href="media-elements.html#media-element">media
  element</a> directly, possibly making use of the <code title="dom-navigator-canPlayType"><a href="media-elements.html#dom-navigator-canplaytype">canPlayType()</a></code> method to
  pick from amongst available resources. Generally, manipulating
  <code><a href="#the-source-element">source</a></code> elements manually after the document has been
  parsed is an unnecessarily complicated approach.</p>

  <p>The <dfn id="attr-source-type" title="attr-source-type"><code>type</code></dfn>
  attribute gives the type of the <a href="media-elements.html#media-resource">media resource</a>, to help
  the user agent determine if it can play this <a href="media-elements.html#media-resource">media
  resource</a> before fetching it. If specified, its value must be
  a <a href="infrastructure.html#valid-mime-type">valid MIME type</a>. The <code title="">codecs</code>
  parameter, which certain MIME types define, might be necessary to
  specify exactly how the resource is encoded. <a href="references.html#refsRFC4281">[RFC4281]</a></p>

  <div class="example">

   <p>The following list shows some examples of how to use the <code title="">codecs=</code> MIME parameter in the <code title="attr-source-type"><a href="#attr-source-type">type</a></code> attribute.</p>

 we have all kinds of quirks we should define if they come up during
 testing, as e.g. shown in:
 http://mxr.mozilla.org/mozilla-central/source/layout/generic/nsObjectFrame.cpp
 http://trac.webkit.org/browser/trunk/WebCore/html/HTMLEmbedElement.cpp
 http://trac.webkit.org/browser/trunk/WebCore/rendering/RenderPartObject.cpp (updateWidget)
 e.g. - 240x200 default
      - the attributes/params are sent in a name-value pair list as follows (for Gecko):
         + attributes of the element, in source order
         + a synthesised 'src' attribute, if there was no 'src' but
           there was a 'data', with the value of the 'data' attribute
         + the params, in source order
        (WebKit does something different still)
      - the HIDDEN attribute (might be moot now)

  <p class="warning">Plugins that cannot be <a href="infrastructure.html#concept-plugin-secure" title="concept-plugin-secure">secured</a> are disabled in

    component of the <a href="urls.html#url">URL</a> of the specified resource (after

    supports, then the <a href="#concept-embed-type" title="concept-embed-type">content's
    type</a> is the type that that plugin can handle.</p>

    <p class="example">For example, a plugin might say that it can
    handle resources with <a href="urls.html#url-path" title="url-path">&lt;path&gt;</a>
    components that end with the four character string "<code title="">.swf</code>".</p>

    <!-- it's sad that we have to do extension sniffing. sigh. -->
    <!-- see also <object> which has a similar step -->

   </li>

   <li><p>Otherwise, if the specified resource has <a href="urls.html#content-type" title="Content-Type">explicit Content-Type metadata</a>, then
   that is the <a href="#concept-embed-type" title="concept-embed-type">content's
   type</a>.</p></li>

   <li><p>Otherwise, the content has no type and there can be no
   appropriate <a href="infrastructure.html#plugin">plugin</a> for it.</p></li>

   <!-- This algorithm is a monument to bad design. Go legacy! -->

  </ol><p>The <code><a href="#the-embed-element">embed</a></code> element has no <a href="content-models.html#fallback-content">fallback
  content</a>. If the user agent can't find a suitable plugin, then
  the user agent must use a default plugin. (This default could be as
  simple as saying "Unsupported Format".)</p>

  <p>Whether the resource is fetched successfully or not (e.g. whether
  the response code was a 2xx code <a href="urls.html#concept-http-equivalent-codes" title="concept-http-equivalent-codes">or equivalent</a>) must be
  ignored when determining the resource's type and when handing the
  resource to the plugin.</p>

  <p class="note">This allows servers to return data for plugins even
  with error responses (e.g. HTTP 500 Internal Server Error codes can
  still contain plugin data).</p>

  <a href="infrastructure.html#plugin">plugin</a>.</p>

  <div class="impl">

  <p>The user agent should pass the names and values of all the
  attributes of the <code><a href="#the-embed-element">embed</a></code> element that have no namespace
  to the <a href="infrastructure.html#plugin">plugin</a> used, when it is instantiated.</p>

  <p>The <code><a href="#htmlembedelement">HTMLEmbedElement</a></code> object representing the element
  must expose the scriptable interface of the <a href="infrastructure.html#plugin">plugin</a>
  instantiated for the <code><a href="#the-embed-element">embed</a></code> element. At a minimum, this
  interface must implement the <dfn id="dom-embed-caller" title="dom-embed-caller">legacy
  caller operation</dfn>. (It is suggested that the default behavior
  of this legacy caller operation, e.g. the behavior of the default
  plugin's legacy caller operation, be to throw a
  <code><a href="infrastructure.html#notsupportederror">NotSupportedError</a></code> exception.)</p>

  </div>

  <p>The <code><a href="#the-embed-element">embed</a></code> element supports <a href="dimension-attributes.html#dimension-attributes">dimension
  attributes</a>.</p>

  <div class="impl">

  <p>The IDL attributes <dfn id="dom-embed-src" title="dom-embed-src"><code>src</code></dfn> and <dfn id="dom-embed-type" title="dom-embed-type"><code>type</code></dfn> each must
  <a href="common-dom-interfaces.html#reflect">reflect</a> the respective content attributes of the same
  name.</p>

  </div>

  <div class="example">

   <p>Here's a way to embed a resource that requires a proprietary
   plugin, like Flash:</p>

   <pre>&lt;embed src="catgame.swf"&gt;</pre>

   <p>If the user does not have the plugin (for example if the
   plugin vendor doesn't support the user's platform), then the user
   will be unable to use the resource.</p>

   <p>To pass the plugin a parameter "quality" with the value "high",
   an attribute can be specified:</p>

   <pre>&lt;embed src="catgame.swf" quality="high"&gt;</pre>

   <p>This would be equivalent to the following, when using an
   <code><a href="the-object-element.html#the-object-element">object</a></code> element instead:</p>

   <pre>&lt;object data="catgame.swf"&gt;
 &lt;param name="quality" value="high"&gt;
&lt;/object&gt;</pre>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-ins-element">ins</a></code> element <a href="rendering.html#represents">represents</a> an addition
  to the document.</p>

  <div class="example">

   <p>The following represents the addition of a single paragraph:</p>

   <pre>&lt;aside&gt;
 &lt;ins&gt;
  &lt;p&gt; I like fruit. &lt;/p&gt;
 &lt;/ins&gt;
&lt;/aside&gt;</pre>

   <p>As does the following, because everything in the
   <code><a href="the-aside-element.html#the-aside-element">aside</a></code> element here counts as <a href="content-models.html#phrasing-content-1">phrasing
   content</a> and therefore there is just one
   <a href="content-models.html#paragraph">paragraph</a>:</p>

   <pre>&lt;aside&gt;
 &lt;ins&gt;
  Apples are &lt;em&gt;tasty&lt;/em&gt;.
 &lt;/ins&gt;
 &lt;ins&gt;
  So are pears.
 &lt;/ins&gt;
&lt;/aside&gt;</pre>

  </div>

  <p><code><a href="#the-ins-element">ins</a></code> elements should not cross <a href="content-models.html#paragraph" title="paragraph">implied paragraph</a> boundaries.</p>

  <div class="example">

   <p>The following example represents the addition of two paragraphs,
   the second of which was inserted in two parts. The first
   <code><a href="#the-ins-element">ins</a></code> element in this example thus crosses a paragraph
   boundary, which is considered poor form.</p>

   <pre class="bad">&lt;aside&gt;
 &lt;!-- don't do this --&gt;
 &lt;ins datetime="2005-03-16 00:00Z"&gt;
  &lt;p&gt; I like fruit. &lt;/p&gt;
  Apples are &lt;em&gt;tasty&lt;/em&gt;.
 &lt;/ins&gt;
 &lt;ins datetime="2007-12-19 00:00Z"&gt;
  So are pears.
 &lt;/ins&gt;
&lt;/aside&gt;</pre>

   <p>Here is a better way of marking this up. It uses more elements,
   but none of the elements cross implied paragraph boundaries.</p>

   <pre>&lt;aside&gt;
 &lt;ins datetime="2005-03-16 00:00Z"&gt;
  &lt;p&gt; I like fruit. &lt;/p&gt;
 &lt;/ins&gt;
 &lt;ins datetime="2005-03-16 00:00Z"&gt;
  Apples are &lt;em&gt;tasty&lt;/em&gt;.
 &lt;/ins&gt;
 &lt;ins datetime="2007-12-19 00:00Z"&gt;
  So are pears.
 &lt;/ins&gt;
&lt;/aside&gt;</pre>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-em-element">em</a></code> element <a href="rendering.html#represents">represents</a> stress
  emphasis of its contents.</p>

  <p>The level of stress that a particular piece of content has is
  given by its number of ancestor <code><a href="#the-em-element">em</a></code> elements.</p>

  <p>The placement of stress emphasis changes the meaning of the
  sentence. The element thus forms an integral part of the content.
  The precise way in which stress is used in this way depends on the
  language.</p>

  <div class="example">

   <p>These examples show how changing the stress emphasis changes the
   meaning. First, a general statement of fact, with no stress:</p>

   <pre>&lt;p&gt;Cats are cute animals.&lt;/p&gt;</pre>

   <p>By emphasizing the first word, the statement implies that the
   kind of animal under discussion is in question (maybe someone is
   asserting that dogs are cute):</p>

   <pre>&lt;p&gt;&lt;em&gt;Cats&lt;/em&gt; are cute animals.&lt;/p&gt;</pre>

   <p>Moving the stress to the verb, one highlights that the truth of
   the entire sentence is in question (maybe someone is saying cats
   are not cute):</p>

   <pre>&lt;p&gt;Cats &lt;em&gt;are&lt;/em&gt; cute animals.&lt;/p&gt;</pre>

   <p>By moving it to the adjective, the exact nature of the cats
   is reasserted (maybe someone suggested cats were <em>mean</em>
   animals):</p>

   <pre>&lt;p&gt;Cats are &lt;em&gt;cute&lt;/em&gt; animals.&lt;/p&gt;</pre>

   <p>Similarly, if someone asserted that cats were vegetables,
   someone correcting this might emphasize the last word:</p>

   <pre>&lt;p&gt;Cats are cute &lt;em&gt;animals&lt;/em&gt;.&lt;/p&gt;</pre>

   <p>By emphasizing the entire sentence, it becomes clear that the
   speaker is fighting hard to get the point across. This kind of
   stress emphasis also typically affects the punctuation, hence the
   exclamation mark here.</p>

   <pre>&lt;p&gt;&lt;em&gt;Cats are cute animals!&lt;/em&gt;&lt;/p&gt;</pre>

   <p>Anger mixed with emphasizing the cuteness could lead to markup
   such as:</p>

   <pre>&lt;p&gt;&lt;em&gt;Cats are &lt;em&gt;cute&lt;/em&gt; animals!&lt;/em&gt;&lt;/p&gt;</pre>

  </div>

  <div class="note">

   <p>The <code><a href="#the-em-element">em</a></code> element isn't a generic "italics"
   element. Sometimes, text is intended to stand out from the rest of
   the paragraph, as if it was in a different mood or voice. For this,
   the <code><a href="the-i-element.html#the-i-element">i</a></code> element is more appropriate.</p>

   <p>The <code><a href="#the-em-element">em</a></code> element also isn't intended to convey
   importance; for that purpose, the <code><a href="the-strong-element.html#the-strong-element">strong</a></code> element is
   more appropriate.</p>

   <!--

    Thus the following is a bad use of <em>:

      <p><em>Note</em>: ...</p>

    You should use <strong> or <i> for this instead (depending on
    exactly what you're doing).

  source.</p>

  <p>Quotation punctuation (such as quotation marks) that is quoting
  the contents of the element must not appear immediately before,
  after, or inside <code><a href="#the-q-element">q</a></code> elements; they will be inserted into
  the rendering by the user agent.</p>

  <p>Content inside a <code><a href="#the-q-element">q</a></code> element must be quoted from
  another source, whose address, if it has one, may be cited in the
  <dfn id="attr-q-cite" title="attr-q-cite"><code>cite</code></dfn> attribute. The
  source may be fictional, as when quoting characters in a novel or
  screenplay.</p>

  <p>If the <code title="attr-q-cite"><a href="#attr-q-cite">cite</a></code> attribute is
  present, it must be a <a href="urls.html#valid-url-potentially-surrounded-by-spaces">valid URL potentially surrounded by
  spaces</a>. <span class="impl">To obtain the corresponding
  citation link, the value of the attribute must be <a href="urls.html#resolve-a-url" title="resolve a url">resolved</a> relative to the element. User
  agents should allow users to follow such citation links.</span></p>

  <p>The <code><a href="#the-q-element">q</a></code> element must not be used in place of quotation
  marks that do not represent quotes; for example, it is inappropriate
  to use the <code><a href="#the-q-element">q</a></code> element for marking up sarcastic
  statements.</p>

  <p>The use of <code><a href="#the-q-element">q</a></code> elements to mark up quotations is
  entirely optional; using explicit quotation punctuation without
  <code><a href="#the-q-element">q</a></code> elements is just as correct.</p>

  <div class="example">

   <p>Here is a simple example of the use of the <code><a href="#the-q-element">q</a></code>
   element:</p>

   <pre>&lt;p&gt;The man said &lt;q&gt;Things that are impossible just take
longer&lt;/q&gt;. I disagreed with him.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>Here is an example with both an explicit citation link in the
   <code><a href="#the-q-element">q</a></code> element, and an explicit citation outside:</p>

   <pre>&lt;p&gt;The W3C page &lt;cite&gt;About W3C&lt;/cite&gt; says the W3C's
mission is &lt;q cite="http://www.w3.org/Consortium/"&gt;To lead the
World Wide Web to its full potential by developing protocols and
guidelines that ensure long-term growth for the Web&lt;/q&gt;. I
disagree with this mission.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>In the following example, the quotation itself contains a
   quotation:</p>

   <pre>&lt;p&gt;In &lt;cite&gt;Example One&lt;/cite&gt;, he writes &lt;q&gt;The man
said &lt;q&gt;Things that are impossible just take longer&lt;/q&gt;. I
disagreed with him&lt;/q&gt;. Well, I disagree even more!&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>In the following example, quotation marks are used instead of
   the <code><a href="#the-q-element">q</a></code> element:</p>

   <pre>&lt;p&gt;His best argument was &#10077;I disagree&#10078;, which
I thought was laughable.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>In the following example, there is no quote &#8212; the
   quotation marks are used to name a word. Use of the <code><a href="#the-q-element">q</a></code>
   element in this case would be inappropriate.</p>

   <pre>&lt;p&gt;The word "ineffable" could have been used to describe the disaster
resulting from the campaign's mismanagement.&lt;/p&gt;</pre>

  <p>The <dfn id="attr-style-media" title="attr-style-media"><code>media</code></dfn>
  attribute says which media the styles apply to. The value must be a
  <a href="common-microsyntaxes.html#valid-media-query">valid media query</a>.  <span class="impl">The user agent
  must apply the styles when the <code title="attr-style-media"><a href="#attr-style-media">media</a></code> attribute's value
  <a href="common-microsyntaxes.html#matches-the-environment">matches the environment</a> and the other relevant
  conditions apply, and must not apply them otherwise.</span></p><!--
  note similar text in <link> section -->

  <div class="impl">

  <p class="note">The styles might be further limited in scope,
  e.g. in CSS with the use of <code title="">@media</code>
  blocks. This specification does not override such further
  restrictions or requirements.</p><!-- note similar text in <link>
  section -->

  </div>

  <p id="style-default-media">The default, if the <code title="attr-style-media"><a href="#attr-style-media">media</a></code> attribute is omitted, is
  "<code title="">all</code>", meaning that by default styles apply to
  all media.</p>

  <p>The <dfn id="attr-style-scoped" title="attr-style-scoped"><code>scoped</code></dfn>
  attribute is a <a href="common-microsyntaxes.html#boolean-attribute">boolean attribute</a>. If present, it
  indicates that the styles are intended just for the subtree rooted
  at the <code><a href="#the-style-element">style</a></code> element's parent element, as opposed to
  the whole <code><a href="dom.html#document">Document</a></code>.</p>

  <p>If the <code title="attr-style-scoped"><a href="#attr-style-scoped">scoped</a></code> attribute is
  present and the element has a parent element, then the
  <code><a href="#the-style-element">style</a></code> element must be the first node of <a href="content-models.html#flow-content-1">flow
  content</a> in its parent element other than <a href="content-models.html#inter-element-whitespace">inter-element
  whitespace</a>, and the parent element's content model must not
  have a <a href="content-models.html#transparent">transparent</a> component.</p>

  <p class="note">This implies that only one scoped <code><a href="#the-style-element">style</a></code>
  element is allowed at a time, and that such elements cannot be
  children of, e.g., <code><a href="the-a-element.html#the-a-element">a</a></code> or <code><a href="the-ins-element.html#the-ins-element">ins</a></code> elements, even
  when those are used as <a href="content-models.html#flow-content-1">flow content</a> containers.</p>

  <div class="impl">

  <p>If the <code title="attr-style-scoped"><a href="#attr-style-scoped">scoped</a></code> attribute is
  present, then the user agent must apply the specified style
  information only to the <code><a href="#the-style-element">style</a></code> element's parent element
  (if any), and that element's descendants. Otherwise, the specified
  styles must, if applied, be applied to the entire document.</p>

  <p class="critical">The following will eventually be moved to a CSS
  specification; it is specified here only on an interim basis until
  an editor can be found to own this.</p>

  <p>Within scoped CSS resources, authors may use an <code title="">@global</code> @-rule. The syntax of this rule is defined
  as follows.</p>

  <p>The following production is added to the grammar:</p>

  <pre>global
  : GLOBAL_SYM S* ruleset
  ;</pre>

  <p>The following rules are added to the Flex tokenizer:</p>

  <pre>B                     b|\\0{0,4}(42|62)(\r\n|[ \t\r\n\f])?
@{G}{L}{O}{B}{A}{L}   {return GLOBAL_SYM;}</pre>

  <p>Simple selectors in rule sets prefixed by the <code title="">@global</code> @-rule in scoped CSS resources must be
  processed in the same way as normal rule sets in non-scoped CSS
  resources.</p>

  <p>Simple selectors in scoped CSS resources that are not prefixed by
  an <code title="">@global</code> @-rule must only match the
  <code><a href="#the-style-element">style</a></code> element's parent element (if any), and that
  element's descendants.</p>

  <p>For scoped CSS resources, the effect of other @-rules must be
  scoped to either the scoped sheet and its subresources or to the
  subtree rooted at the <code><a href="#the-style-element">style</a></code> element's parent (if any),
  even if the @-rule in question would ordinarily apply to all style
  sheets that affect the <code><a href="dom.html#document">Document</a></code>, or to all nodes in the
  <code><a href="dom.html#document">Document</a></code>. Any '@page' rules in scoped CSS resources
  must be ignored.</p>

  <p class="example">For example, an '@font-face' rule defined in a
  scoped style sheet would only define the font for the purposes of
  elements in the scoped section; the font would not be used for
  elements outside the subtree. However, rules outside the subtree
  that refer to font names declared in '@font-face' rules in a scoped
  section, when those rules are inherited by nodes in the scoped
  section, would end up referring to the fonts declared in that
  section.</p>

  <p id="title-on-style">The <dfn id="attr-style-title" title="attr-style-title"><code>title</code></dfn> attribute on
  <code><a href="#the-style-element">style</a></code> elements defines <a href="infrastructure.html#alternative-style-sheet-sets">alternative style sheet
  sets</a>. If the <code><a href="#the-style-element">style</a></code> element has no <code title="attr-style-title"><a href="#attr-style-title">title</a></code> attribute, then it has no
  title; the <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute of
  ancestors does not apply to the <code><a href="#the-style-element">style</a></code> element. <a href="references.html#refsCSSOM">[CSSOM]</a></p>

  <p class="note">The <code title="attr-style-title"><a href="#attr-style-title">title</a></code>
  attribute on <code><a href="#the-style-element">style</a></code> elements, like the <code title="attr-link-title"><a href="the-link-element.html#attr-link-title">title</a></code> attribute on <code><a href="the-link-element.html#the-link-element">link</a></code>
  elements, differs from the global <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute in that a
  <code><a href="#the-style-element">style</a></code> block without a title does not inherit the title
  of the parent element: it merely has no title.</p>

  <p>The <code><a href="infrastructure.html#textcontent">textContent</a></code> of a <code><a href="#the-style-element">style</a></code> element must
  match the <code title="">style</code> production in the following
  ABNF, the character set for which is Unicode. <a href="references.html#refsABNF">[ABNF]</a></p>

  <pre>style         = no-c-start *( c-start no-c-end c-end no-c-start )
no-c-start    = &lt;any string that doesn't contain a substring that matches c-start &gt;
c-start       = "&lt;!--"
no-c-end      = &lt;any string that doesn't contain a substring that matches c-end &gt;
c-end         = "--&gt;"</pre>

  <!-- Unmatched comment-like syntax is invalid on a temporary basis,
       waiting for IE, WebKit, and Opera to fix their parsing bug
       whereby such comments trigger a weird escape in which </style>
       is ignored. Otherwise, parsing behaviour in those browsers
       could differ substantially from the parsing behaviour of HTML5.
       Once everyone follows the HTML5 spec, we can drop this
       requirement.

  <div class="impl">

  <p>All descendant elements must be processed, according to their
  semantics, before the <code><a href="#the-style-element">style</a></code> element itself is
  evaluated. For styling languages that consist of pure text (as
  opposed to XML), user agents must evaluate <code><a href="#the-style-element">style</a></code>
  elements by passing the concatenation of the contents of all the
  <code><a href="infrastructure.html#text-0">Text</a></code> nodes that are children of the
  <code><a href="#the-style-element">style</a></code> element (not any other nodes such as comments or
  elements), in <a href="infrastructure.html#tree-order">tree order</a>, to the style system. For
  XML-based styling languages, user agents must pass all the child
  nodes of the <code><a href="#the-style-element">style</a></code> element to the style system.</p>

  <p>All <a href="urls.html#url" title="URL">URLs</a> found by the styling language's
  processor must be <a href="urls.html#resolve-a-url" title="resolve a url">resolved</a>,

  has no <a href="infrastructure.html#critical-subresources">critical subresources</a>, once the style sheet has

  <!-- v2: Apply this to contentEditable elements -->

  <p>The <dfn id="attr-fe-autofocus" title="attr-fe-autofocus"><code>autofocus</code></dfn>

  <h3 id="scripting-1"><span class="secno">4.3 </span>Scripting</h3>

  <p>Scripts allow authors to add interactivity to their documents.</p>

  <p>Authors are encouraged to use declarative alternatives to
  scripting where possible, as declarative mechanisms are often more
  maintainable, and many users disable scripting.</p>

  <div class="example">
   <p>For example, instead of using script to show or hide a section
   to show more details, the <code><a href="the-details-element.html#the-details-element">details</a></code> element could be
   used.</p>
  </div>

  <p>Authors are also encouraged to make their applications degrade
  gracefully in the absence of scripting support.</p>

  <div class="example">
   <p>For example, if an author provides a link in a table header to
   dynamically resort the table, the link could also be made to
   function without scripts by requesting the sorted table from the
   server.</p>
  </div>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-abbr-element">abbr</a></code> element <a href="rendering.html#represents">represents</a> an
  abbreviation or acronym, optionally with its expansion. The <dfn id="attr-abbr-title" title="attr-abbr-title"><code>title</code></dfn> attribute may be
  used to provide an expansion of the abbreviation. The attribute, if
  specified, must contain an expansion of the abbreviation, and
  nothing else.</p>

  <div class="example">
   <p>The paragraph below contains an abbreviation marked up with the
   <code><a href="#the-abbr-element">abbr</a></code> element. This paragraph <a href="the-dfn-element.html#defining-term" title="defining
   term">defines the term</a> "Web Hypertext Application Technology
   Working Group".</p>
   <pre>&lt;p&gt;The &lt;dfn id=whatwg&gt;&lt;abbr
title="Web Hypertext Application Technology Working Group"&gt;WHATWG&lt;/abbr&gt;&lt;/dfn&gt;
is a loose unofficial collaboration of Web browser manufacturers and
interested parties who wish to develop new technologies designed to
allow authors to write and deploy Applications over the World Wide
Web.&lt;/p&gt;</pre>
   <p>An alternative way to write this would be:</p>
   <pre>&lt;p&gt;The &lt;dfn id=whatwg&gt;Web Hypertext Application Technology
Working Group&lt;/dfn&gt; (&lt;abbr
title="Web Hypertext Application Technology Working Group"&gt;WHATWG&lt;/abbr&gt;)
is a loose unofficial collaboration of Web browser manufacturers and
interested parties who wish to develop new technologies designed to
allow authors to write and deploy Applications over the World Wide
Web.&lt;/p&gt;</pre>
  </div>

  <div class="example">
   <p>This paragraph has two abbreviations. Notice how only one is
   defined; the other, with no expansion associated with it, does not
   use the <code><a href="#the-abbr-element">abbr</a></code> element.</p>
   <pre>&lt;p&gt;The
&lt;abbr title="Web Hypertext Application Technology Working Group"&gt;WHATWG&lt;/abbr&gt;
started working on HTML5 in 2004.&lt;/p&gt;</pre>
  </div>

  <div class="example">
   <p>This paragraph links an abbreviation to its definition.</p>
   <pre>&lt;p&gt;The &lt;a href="#whatwg"&gt;&lt;abbr
title="Web Hypertext Application Technology Working Group"&gt;WHATWG&lt;/abbr&gt;&lt;/a&gt;
community does not have much representation from Asia.&lt;/p&gt;</pre>
  </div>

  <div class="example">
   <p>This paragraph marks up an abbreviation without giving an
   expansion, possibly as a hook to apply styles for abbreviations
   (e.g. smallcaps).</p>
   <pre>&lt;p&gt;Philip` and Dashiva both denied that they were going to
get the issue counts from past revisions of the specification to
backfill the &lt;abbr&gt;WHATWG&lt;/abbr&gt; issue graph.&lt;/p&gt;</pre>
  </div>

  <p>If an abbreviation is pluralized, the expansion's grammatical
  number (plural vs singular) must match the grammatical number of the
  contents of the element.</p>

  <div class="example">

   <p>Here the plural is outside the element, so the expansion is in
   the singular:</p>

   <pre>&lt;p&gt;Two &lt;abbr title="Working Group"&gt;WG&lt;/abbr&gt;s worked on
this specification: the &lt;abbr&gt;WHATWG&lt;/abbr&gt; and the
&lt;abbr&gt;HTMLWG&lt;/abbr&gt;.&lt;/p&gt;</pre>

   <p>Here the plural is inside the element, so the expansion is in
   the plural:</p>

   <pre>&lt;p&gt;Two &lt;abbr title="Working Groups"&gt;WGs&lt;/abbr&gt; worked on
this specification: the &lt;abbr&gt;WHATWG&lt;/abbr&gt; and the
&lt;abbr&gt;HTMLWG&lt;/abbr&gt;.&lt;/p&gt;</pre>

  </div>

  <p>Abbreviations do not have to be marked up using this element. It
  is expected to be useful in the following cases:</p>

  <ul><li>Abbreviations for which the author wants to give expansions,
   where using the <code><a href="#the-abbr-element">abbr</a></code> element with a <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute is an alternative to
   including the expansion inline (e.g. in parentheses).</li>

   <li>Abbreviations that are likely to be unfamiliar to the
   document's readers, for which authors are encouraged to either mark
   up the abbreviation using an <code><a href="#the-abbr-element">abbr</a></code> element with a <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute or include the expansion
   inline in the text the first time the abbreviation is used.</li>

   <li>Abbreviations whose presence needs to be semantically
   annotated, e.g. so that they can be identified from a style sheet
   and given specific styles, for which the <code><a href="#the-abbr-element">abbr</a></code> element
   can be used without a <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code>
   attribute.</li>

  </ul><p title="note">Providing an expansion in a <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute once will not necessarily
  cause other <code><a href="#the-abbr-element">abbr</a></code> elements in the same document with the
  same contents but without a <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code>
  attribute to behave as if they had the same expansion. Every
  <code><a href="#the-abbr-element">abbr</a></code> element is independent.</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-caption-element">caption</a></code> element <a href="rendering.html#represents">represents</a> the title of the
  <code><a href="the-table-element.html#the-table-element">table</a></code> that is its parent, if it has a parent and that
  is a <code><a href="the-table-element.html#the-table-element">table</a></code> element.</p>

  <div class="impl">

  <p>The <code><a href="#the-caption-element">caption</a></code> element takes part in the <a href="attributes-common-to-td-and-th-elements.html#table-model">table
  model</a>.</p>

  </div>

  <p>When a <code><a href="the-table-element.html#the-table-element">table</a></code> element is the only content in a
  <code><a href="the-figure-element.html#the-figure-element">figure</a></code> element other than the <code><a href="the-figcaption-element.html#the-figcaption-element">figcaption</a></code>,
  the <code><a href="#the-caption-element">caption</a></code> element should be omitted in favor of the
  <code><a href="the-figcaption-element.html#the-figcaption-element">figcaption</a></code>.</p>

  <p>A caption can introduce context for a table, making it
  significantly easier to understand.</p>

  <div class="example">

   <p>Consider, for instance, the following table:</p>

   <table class="dice-example"><tr><th>   </th><th> 1 </th><th> 2 </th><th> 3 </th><th> 4 </th><th> 5 </th><th> 6
    </th></tr><tr><th> 1 </th><td> 2 </td><td> 3 </td><td> 4 </td><td> 5 </td><td> 6 </td><td> 7
    </td></tr><tr><th> 2 </th><td> 3 </td><td> 4 </td><td> 5 </td><td> 6 </td><td> 7 </td><td> 8
    </td></tr><tr><th> 3 </th><td> 4 </td><td> 5 </td><td> 6 </td><td> 7 </td><td> 8 </td><td> 9
    </td></tr><tr><th> 4 </th><td> 5 </td><td> 6 </td><td> 7 </td><td> 8 </td><td> 9 </td><td> 10
    </td></tr><tr><th> 5 </th><td> 6 </td><td> 7 </td><td> 8 </td><td> 9 </td><td> 10 </td><td> 11
    </td></tr><tr><th> 6 </th><td> 7 </td><td> 8 </td><td> 9 </td><td> 10 </td><td> 11 </td><td> 12
   </td></tr></table><p>In the abstract, this table is not clear. However, with a
   caption giving the table's number (for reference in the main prose)
   and explaining its use, it makes more sense:</p>

   <pre>&lt;caption&gt;
&lt;p&gt;Table 1.
&lt;p&gt;This table shows the total score obtained from rolling two
six-sided dice. The first row represents the value of the first die,
the first column the value of the second die. The total is given in
the cell that corresponds to the values of the two dice.
&lt;/caption&gt;</pre>

  <h4 id="edits-and-paragraphs"><span class="secno">4.7.4 </span>Edits and paragraphs</h4>

  <p><i>This section is non-normative.</i></p>
  <p>Since the <code><a href="the-ins-element.html#the-ins-element">ins</a></code> and <code><a href="the-del-element.html#the-del-element">del</a></code> elements do not
  affect <a href="content-models.html#paragraph" title="paragraph">paragraphing</a>, it is possible,
  in some cases where paragraphs are <a href="content-models.html#paragraph" title="paragraph">implied</a> (without explicit <code><a href="the-p-element.html#the-p-element">p</a></code>
  elements), for an <code><a href="the-ins-element.html#the-ins-element">ins</a></code> or <code><a href="the-del-element.html#the-del-element">del</a></code> element to
  span both an entire paragraph or other non-<a href="content-models.html#phrasing-content-1">phrasing
  content</a> elements and part of another paragraph. For
  example:</p>

  <pre>&lt;section&gt;
 &lt;ins&gt;
  &lt;p&gt;
   This is a paragraph that was inserted.
  &lt;/p&gt;
  This is another paragraph whose first sentence was inserted
  at the same time as the paragraph above.
 &lt;/ins&gt;
 This is a second sentence, which was there all along.
&lt;/section&gt;</pre>

  <p>By only wrapping some paragraphs in <code><a href="the-p-element.html#the-p-element">p</a></code> elements, one
  can even get the end of one paragraph, a whole second paragraph,
  and the start of a third paragraph to be covered by the same
  <code><a href="the-ins-element.html#the-ins-element">ins</a></code> or <code><a href="the-del-element.html#the-del-element">del</a></code> element (though this is very
  confusing, and not considered good practice):</p>

  <pre class="bad">&lt;section&gt;
 This is the first paragraph. &lt;ins&gt;This sentence was
 inserted.
 &lt;p&gt;This second paragraph was inserted.&lt;/p&gt;
 This sentence was inserted too.&lt;/ins&gt; This is the
 third paragraph in this example.
 &lt;!-- (don't do this) --&gt;
&lt;/section&gt;</pre>

  <p>However, due to the way <a href="content-models.html#paragraph" title="paragraph">implied
  paragraphs</a> are defined, it is not possible to mark up the
  end of one paragraph and the start of the very next one using the
  same <code><a href="the-ins-element.html#the-ins-element">ins</a></code> or <code><a href="the-del-element.html#the-del-element">del</a></code> element. You instead have
  to use one (or two) <code><a href="the-p-element.html#the-p-element">p</a></code> element(s) and two
  <code><a href="the-ins-element.html#the-ins-element">ins</a></code> or <code><a href="the-del-element.html#the-del-element">del</a></code> elements, as for example:</p>

  <pre>&lt;section&gt;
 &lt;p&gt;This is the first paragraph. &lt;del&gt;This sentence was
 deleted.&lt;/del&gt;&lt;/p&gt;
 &lt;p&gt;&lt;del&gt;This sentence was deleted too.&lt;/del&gt; That
 sentence needed a separate &amp;lt;del&amp;gt; element.&lt;/p&gt;
&lt;/section&gt;</pre>

  <p>Partly because of the confusion described above, authors are
  strongly encouraged to always mark up all paragraphs with the
  <code><a href="the-p-element.html#the-p-element">p</a></code> element, instead of having <code><a href="the-ins-element.html#the-ins-element">ins</a></code> or
  <code><a href="the-del-element.html#the-del-element">del</a></code> elements that cross <a href="content-models.html#paragraph" title="paragraph">implied
  paragraphs</a> boundaries.</p>

    <p>Creates a <code><a href="the-tr-element.html#the-tr-element">tr</a></code> element, inserts it into the table section at the position given by the argument, and returns the <code><a href="the-tr-element.html#the-tr-element">tr</a></code>.</p>
    <p>The position is relative to the rows in the table section. The index &#8722;1, which is the default if the argument is omitted, is equivalent to inserting at the end of the table section.</p>
    <p>If the given position is less than &#8722;1 or greater than the number of rows, throws an <code><a href="infrastructure.html#indexsizeerror">IndexSizeError</a></code> exception.</p>

    <p>The position is relative to the rows in the table section. The index &#8722;1 is equivalent to deleting the last row of the table section.</p>
    <p>If the given position is less than &#8722;1 or greater than the index of the last row, or if there are no rows, throws an <code><a href="infrastructure.html#indexsizeerror">IndexSizeError</a></code> exception.</p>

  <p>The <dfn id="dom-tbody-rows" title="dom-tbody-rows"><code>rows</code></dfn> attribute

  whose filter matches only <code><a href="the-tr-element.html#the-tr-element">tr</a></code> elements that are children
  of the element.</p>

  <p>The <dfn id="dom-tbody-insertrow" title="dom-tbody-insertRow"><code>insertRow(<var title="">index</var>)</code></dfn> method must, when invoked on an
  element <var title="">table section</var>, act as follows:</p>

  <p>If <var title="">index</var> is less than &#8722;1 or greater than the
  number of elements in the <code title="dom-tbody-rows"><a href="#dom-tbody-rows">rows</a></code>
  collection, the method must throw an <code><a href="infrastructure.html#indexsizeerror">IndexSizeError</a></code>
  exception.</p>

  <p>If <var title="">index</var> is missing, equal to &#8722;1, or
  equal to the number of items in the <code title="dom-tbody-rows"><a href="#dom-tbody-rows">rows</a></code> collection, the method must
  create a <code><a href="the-tr-element.html#the-tr-element">tr</a></code> element, append it to the element <var title="">table section</var>, and return the newly created
  <code><a href="the-tr-element.html#the-tr-element">tr</a></code> element.</p>

  <p>Otherwise, the method must create a <code><a href="the-tr-element.html#the-tr-element">tr</a></code> element,
  insert it as a child of the <var title="">table section</var>
  element, immediately before the <var title="">index</var>th
  <code><a href="the-tr-element.html#the-tr-element">tr</a></code> element in the <code title="dom-tbody-rows"><a href="#dom-tbody-rows">rows</a></code> collection, and finally must
  return the newly created <code><a href="the-tr-element.html#the-tr-element">tr</a></code> element.</p>

  <p>The <dfn id="dom-tbody-deleterow" title="dom-tbody-deleteRow"><code>deleteRow(<var title="">index</var>)</code></dfn> method must remove the <var title="">index</var>th element in the <code title="dom-tbody-rows"><a href="#dom-tbody-rows">rows</a></code> collection from its parent. If
  <var title="">index</var> is less than zero or greater than or equal
  to the number of elements in the <code title="dom-tbody-rows"><a href="#dom-tbody-rows">rows</a></code> collection, the method must
  instead throw an <code><a href="infrastructure.html#indexsizeerror">IndexSizeError</a></code> exception.</p>

  <p>The <dfn id="attr-menu-type" title="attr-menu-type"><code>type</code></dfn> attribute
  is an <a href="common-microsyntaxes.html#enumerated-attribute">enumerated attribute</a> indicating the kind of menu
  being declared. The attribute has three states. The <code title="attr-menu-type-context">context</code> keyword maps to the
  <dfn id="context-menu-state" title="context menu state">context menu</dfn> state, in which
  the element is declaring a context menu. The <code title="attr-menu-type-toolbar">toolbar</code> keyword maps to the
  <dfn id="toolbar-state" title="toolbar state">toolbar</dfn> state, in which the
  element is declaring a toolbar. The attribute may also be
  omitted. The <i>missing value default</i> is the <dfn id="list-state" title="list
  state">list</dfn> state, which indicates that the element is merely
  a list of commands that is neither declaring a context menu nor
  defining a toolbar.</p>

  <p>If a <code><a href="#the-menu-element">menu</a></code> element's <code title="attr-menu-type"><a href="#attr-menu-type">type</a></code> attribute is in the <a href="#context-menu-state" title="context menu state">context menu</a> state, then the
  element <a href="rendering.html#represents">represents</a> the commands of a context menu, and
  the user can only interact with the commands if that context menu is
  activated.</p>

  <p>If a <code><a href="#the-menu-element">menu</a></code> element's <code title="attr-menu-type"><a href="#attr-menu-type">type</a></code> attribute is in the <a href="#toolbar-state" title="toolbar state">toolbar</a> state, then the element
  <a href="rendering.html#represents">represents</a> a list of active commands that the user can
  immediately interact with.</p>

  <p>If a <code><a href="#the-menu-element">menu</a></code> element's <code title="attr-menu-type"><a href="#attr-menu-type">type</a></code> attribute is in the <a href="#list-state" title="list state">list</a> state, then the element either
  <a href="rendering.html#represents">represents</a> an unordered list of items (each represented
  by an <code><a href="the-li-element.html#the-li-element">li</a></code> element), each of which represents a command
  that the user can perform or activate, or, if the element has no
  <code><a href="the-li-element.html#the-li-element">li</a></code> element children, <a href="content-models.html#flow-content-1">flow content</a>
  describing available commands.</p>

  <p>The <dfn id="attr-menu-label" title="attr-menu-label"><code>label</code></dfn>
  attribute gives the label of the menu. It is used by user agents to
  display nested menus in the UI. For example, a context menu
  containing another menu would use the nested menu's <code title="attr-menu-label"><a href="#attr-menu-label">label</a></code> attribute for the submenu's
  menu label.</p>

  <h5 id="menus-intro"><span class="secno">4.11.4.1 </span>Introduction</h5>

  <p><i>This section is non-normative.</i></p>
  <p>The <code><a href="#the-menu-element">menu</a></code> element is used to define context menus and
  toolbars.</p>

  <p>For example, the following represents a toolbar with three menu
  buttons on it, each of which has a dropdown menu with a series of
  options:</p>

  <pre>&lt;menu type="toolbar"&gt;
 &lt;li&gt;
  &lt;menu label="File"&gt;
   &lt;button type="button" onclick="fnew()"&gt;New...&lt;/button&gt;
   &lt;button type="button" onclick="fopen()"&gt;Open...&lt;/button&gt;
   &lt;button type="button" onclick="fsave()"&gt;Save&lt;/button&gt;
   &lt;button type="button" onclick="fsaveas()"&gt;Save as...&lt;/button&gt;
  &lt;/menu&gt;
 &lt;/li&gt;
 &lt;li&gt;
  &lt;menu label="Edit"&gt;
   &lt;button type="button" onclick="ecopy()"&gt;Copy&lt;/button&gt;
   &lt;button type="button" onclick="ecut()"&gt;Cut&lt;/button&gt;
   &lt;button type="button" onclick="epaste()"&gt;Paste&lt;/button&gt;
  &lt;/menu&gt;
 &lt;/li&gt;
 &lt;li&gt;
  &lt;menu label="Help"&gt;
   &lt;li&gt;&lt;a href="help.html"&gt;Help&lt;/a&gt;&lt;/li&gt;
   &lt;li&gt;&lt;a href="about.html"&gt;About&lt;/a&gt;&lt;/li&gt;
  &lt;/menu&gt;
 &lt;/li&gt;
&lt;/menu&gt;</pre>

  <p>In a supporting user agent, this might look like this:</p>

  <p><img alt="A toolbar with three buttons, labeled 'File', 'Edit', and 'Help'; where if you select the 'Edit' button you get a drop-down menu with three more options, 'Copy', 'Cut', and 'Paste'." height="101" src="images/sample-toolbar-1.png" width="303"></p>

  <p>In a legacy user agent, the above would look like a bulleted list
  with three items, the first of which has four buttons, the second of
  which has three, and the third of which has two nested bullet points
  with two items consisting of links.</p>

  <hr><p>The following implements a similar toolbar, with a single button
  whose values, when selected, redirect the user to Web sites.</p>

  <pre>&lt;form action="redirect.cgi"&gt;
 &lt;menu type="toolbar"&gt;
  &lt;label for="goto"&gt;Go to...&lt;/label&gt;
  &lt;menu label="Go"&gt;
   &lt;select id="goto"<!--
           onchange="if (this.options[this.selectedIndex].value)
                     window.location = this.options[this.selectedIndex].value"-->&gt;
    &lt;option value="" selected="selected"&gt; Select site: &lt;/option&gt;
    &lt;option value="http://www.apple.com/"&gt; Apple &lt;/option&gt;
    &lt;option value="http://www.mozilla.org/"&gt; Mozilla &lt;/option&gt;
    &lt;option value="http://www.opera.com/"&gt; Opera &lt;/option&gt;
   &lt;/select&gt;
   &lt;span&gt;&lt;input type="submit" value="Go"&gt;&lt;/span&gt;
  &lt;/menu&gt;
 &lt;/menu&gt;
&lt;/form&gt;</pre>

  <p>The behavior in supporting user agents is similar to the example
  above, but here the legacy behavior consists of a single
  <code><a href="the-select-element.html#the-select-element">select</a></code> element with a submit button. The submit button
  doesn't appear in the toolbar, because it is not a child of the
  <code><a href="#the-menu-element">menu</a></code> element or of its <code><a href="the-li-element.html#the-li-element">li</a></code> children.</p>



  <div class="impl">

  <h5 id="building-menus-and-toolbars"><span class="secno">4.11.4.2 </span><dfn>Building menus and toolbars</dfn></h5>

  <p>A menu (or toolbar) consists of a list of zero or more of the
  following components:</p>

  <ul class="brief"><li><a href="commands.html#concept-command" title="concept-command">Commands</a>, which can be marked as default commands</li>
   <li>Separators</li>
   <li>Other menus (which allows the list to be nested)</li>
  </ul><p>The list corresponding to a particular <code><a href="#the-menu-element">menu</a></code> element
  is built by iterating over its child nodes. For each child node in
  <a href="infrastructure.html#tree-order">tree order</a>, the required behavior depends on what the
  node is, as follows:</p>

  <dl class="switch"><dt>An element that <a href="commands.html#concept-command" title="concept-command">defines a command</a></dt>

   <dd>Append the command to the menu, respecting its <a href="commands.html#concept-facet" title="concept-facet">facets</a><!-- we might need to be
   explicit about what this means for each facet, if testing shows
   this isn't well-implemented. e.g.: If there's an Icon facet for the
   command, it should be <span title="fetch">fetched</span><!- -FETCH-
   -> (this would be http-origin privacy-sensitive), and then that
   image should be associated with the command, such that each command
   only has its image fetched once, to prevent changes to the base URL
   from having effects after the image has been fetched once. (no need
   to resolve the Icon facet, it's an absolute URL) -->. <!--If the
   element is a <code>command</code> element with a <code
   title="attr-command-default">default</code> attribute, mark the
   command as being a default command.--></dd>


   <dt>An <code><a href="the-hr-element.html#the-hr-element">hr</a></code> element</dt>
   <dt>An <code><a href="the-option-element.html#the-option-element">option</a></code> element that has a <code title="attr-option-value"><a href="the-option-element.html#attr-option-value">value</a></code> attribute set to the empty
   string, and has a <code title="attr-option-disabled"><a href="the-option-element.html#attr-option-disabled">disabled</a></code> attribute, and whose
   <code><a href="infrastructure.html#textcontent">textContent</a></code> consists of a string of one or more
   hyphens (U+002D HYPHEN-MINUS)</dt>

   <dd>Append a separator to the menu.</dd>


   <dt>An <code><a href="the-li-element.html#the-li-element">li</a></code> element</dt>
   <dt>A <code><a href="the-label-element.html#the-label-element">label</a></code> element</dt>

   <dd>Iterate over the children of the element.</dd>


   <dt>A <code><a href="#the-menu-element">menu</a></code> element with no <code title="attr-menu-label"><a href="#attr-menu-label">label</a></code> attribute</dt>
   <dt>A <code><a href="the-select-element.html#the-select-element">select</a></code> element</dt>

   <dd>Append a separator to the menu, then iterate over the children
   of the <code><a href="#the-menu-element">menu</a></code> or <code><a href="the-select-element.html#the-select-element">select</a></code> element, then
   append another separator.</dd>

   <!-- v2: we might want to support <select> in <label> as giving a named submenu -->


   <dt>A <code><a href="#the-menu-element">menu</a></code> element with a <code title="attr-menu-label"><a href="#attr-menu-label">label</a></code> attribute</dt>
   <dt>An <code><a href="the-optgroup-element.html#the-optgroup-element">optgroup</a></code> element with a <code title="attr-menu-label"><a href="#attr-menu-label">label</a></code> attribute</dt>

   <dd>Append a submenu to the menu, using the value of the element's
   <code title="">label</code> attribute as the label of the menu. The
   submenu must be constructed by taking the element and creating a
   new menu for it using the complete process described in this
   section.</dd>


   <dt>Any other node</dt>

   <dd><a href="infrastructure.html#ignore">Ignore</a> the node.</dd>

  </dl><p>Once all the nodes have been processed as described above, the
  user agent must the post-process the menu as follows:</p>

  <ol><li>Except for separators, any menu item with no label, or whose
   label is the empty string, must be removed.</li>

   <li>Any sequence of two or more separators in a row must be
   collapsed to a single separator.</li>

   <li>Any separator at the start or end of the menu must be
   removed.</li>

  </ol></div>




  <h5 id="context-menus"><span class="secno">4.11.4.3 </span><dfn>Context menus</dfn></h5>

  <p>The <dfn id="attr-contextmenu" title="attr-contextmenu"><code>contextmenu</code></dfn>
  attribute gives the element's <a href="#context-menus" title="context menus">context
  menu</a>. The value must be the <a href="infrastructure.html#concept-id" title="concept-id">ID</a> of a <code><a href="#the-menu-element">menu</a></code> element in the
  DOM. <span class="impl">If the node that would be obtained by
  invoking the <code title="dom-Document-getElementById"><a href="infrastructure.html#dom-document-getelementbyid">getElementById()</a></code> method
  using the attribute's value as the only argument is null or not a
  <code><a href="#the-menu-element">menu</a></code> element, then the element has no assigned context
  menu. Otherwise, the element's assigned context menu is the element
  so identified.</span></p>

  <div class="impl">

  <p>When an element's context menu is requested (e.g. by the user
  right-clicking the element, or pressing a context menu key), the
  user agent must apply the appropriate rules from the following
  list:</p>

  <dl class="switch"><dt>If the user requested a context menu using a pointing device</dt>

   <dd><p>The user agent must fire an event with the name <code title="event-contextmenu">contextmenu</code>, that bubbles and is
   cancelable, and that uses the <code><a href="infrastructure.html#mouseevent-10">MouseEvent</a></code> interface, at
   the element for which the menu was requested. The context
   information of the event must be initialized to the same values as
   the last <code><a href="infrastructure.html#mouseevent-10">MouseEvent</a></code> user interaction event that was
   fired as part of the gesture that that was interpreted as a request
   for the context menu.</p></dd>

   <dt>Otherwise</dt>

   <dd><p>The user agent must <a href="webappapis.html#fire-a-synthetic-mouse-event" title="fire a synthetic mouse
   event">fire a synthetic mouse event named <code title="event-contextmenu">contextmenu</code></a> that bubbles
   and is cancelable at the element for which the menu was
   requested.</p></dd>

  </dl><p class="note">Typically, therefore, the firing of the <code title="event-contextmenu">contextmenu</code> event will be the
  default action of a <code title="mouseup">mouseup</code> or <code title="event-keyup">keyup</code> event. The exact sequence of events
  is UA-dependent, as it will vary based on platform conventions.</p>

  <p>The default action of the <code title="event-contextmenu">contextmenu</code> event depends on
  whether the element or one of its ancestors has a context menu
  assigned (using the <code title="attr-contextmenu"><a href="#attr-contextmenu">contextmenu</a></code> attribute) or not. If
  there is no context menu assigned, the default action must be for
  the user agent to show its default context menu, if it has one.</p>

  <p>If the element or one of its ancestors <em>does</em> have a
  context menu assigned, then the user agent must <a href="webappapis.html#fire-a-simple-event">fire a simple
  event</a> named <code title="event-show">show</code> at the
  <code><a href="#the-menu-element">menu</a></code> element of the context menu of the nearest
  ancestor (including the element itself) with one assigned.</p>
  <!-- v2: include modifier key information -->

  <p>The default action of <em>this</em> event is that the user agent
  must show a context menu <a href="#building-menus-and-toolbars" title="building menus and
  toolbars">built</a> from the <code><a href="#the-menu-element">menu</a></code> element.</p>

  <p>The user agent may also provide access to its default context
  menu, if any, with the context menu shown. For example, it could
  merge the menu items from the two menus together, or provide the
  page's context menu as a submenu of the default menu.</p>

  <p>If the user dismisses the menu without making a selection,
  nothing in particular happens.</p>

  <p>If the user selects a menu item that represents a <a href="commands.html#concept-command" title="concept-command">command</a>, then the UA must invoke
  that command's <a href="commands.html#command-facet-action" title="command-facet-Action">Action</a>.</p>

  <p>Context menus must not, while being shown, reflect changes in the
  DOM; they are constructed as the default action of the <code title="event-show">show</code> event and must remain as constructed
  until dismissed.</p>

  <p>User agents may provide means for bypassing the context menu
  processing model, ensuring that the user can always access the UA's
  default context menus. For example, the user agent could handle
  right-clicks that have the Shift key depressed in such a way that it
  does not fire the <code title="event-contextmenu">contextmenu</code>
  event and instead always shows the default context menu.</p>

  <p>The <dfn id="dom-contextmenu" title="dom-contextMenu"><code>contextMenu</code></dfn>
  IDL attribute must <a href="common-dom-interfaces.html#reflect">reflect</a> the <code title="attr-contextmenu"><a href="#attr-contextmenu">contextmenu</a></code> content attribute.</p>

  </div>

  <div class="example">

   <p>Here is an example of a context menu for an input control:</p>

   <pre>&lt;form name="npc"&gt;
 &lt;label&gt;Character name: &lt;input name=char type=text contextmenu=namemenu required&gt;&lt;/label&gt;
 &lt;menu type=context id=namemenu&gt;
  &lt;command label="Pick random name" onclick="document.forms.npc.elements.char.value = getRandomName()"&gt;
  &lt;command label="Prefill other fields based on name" onclick="prefillFields(document.forms.npc.elements.char.value)"&gt;
 &lt;/menu&gt;
&lt;/form&gt;</pre>

   <p>This adds two items to the control's context menu, one called
   "Pick random name", and one called "Prefill other fields based on
   name". They invoke scripts that are not shown in the example
   above.</p>

  </div>



  <div class="impl">

  <h5 id="toolbars"><span class="secno">4.11.4.4 </span><dfn>Toolbars</dfn></h5>

  <p>When a <code><a href="#the-menu-element">menu</a></code> element has a <code title="attr-menu-type"><a href="#attr-menu-type">type</a></code> attribute in the <a href="#toolbar-state" title="toolbar state">toolbar</a> state, then the user agent
  must <a href="#building-menus-and-toolbars" title="building menus and toolbars">build</a> the
  menu for that <code><a href="#the-menu-element">menu</a></code> element, and use the result in the
  rendering.</p>

  <p>The user agent must reflect changes made to the
  <code><a href="#the-menu-element">menu</a></code>'s DOM, by immediately <a href="#building-menus-and-toolbars" title="building menus
  and toolbars">rebuilding</a> the menu.</p>

  <p>The <code><a href="the-link-element.html#the-link-element">link</a></code> and <code><a href="the-style-element.html#the-style-element">style</a></code> elements can provide
  styling information for the user agent to use when rendering the
  document. The CSS and CSSOM specifications specify what styling
  information is to be used by the user agent and how it is to be
  used. <a href="references.html#refsCSS">[CSS]</a> <a href="references.html#refsCSSOM">[CSSOM]</a></p>

  <p>The <code><a href="the-style-element.html#the-style-element">style</a></code> and <code><a href="the-link-element.html#the-link-element">link</a></code> elements implement
  the <code><a href="infrastructure.html#linkstyle">LinkStyle</a></code> interface. <a href="references.html#refsCSSOM">[CSSOM]</a></p>

  <div class="impl">

  <p>For <code><a href="the-style-element.html#the-style-element">style</a></code> elements, if the user agent does not
  support the specified styling language, then the <code title="dom-LinkStyle-sheet"><a href="infrastructure.html#dom-linkstyle-sheet">sheet</a></code> attribute of the element's
  <code><a href="infrastructure.html#linkstyle">LinkStyle</a></code> interface must return null. Similarly,
  <code><a href="the-link-element.html#the-link-element">link</a></code> elements that do not represent <a href="links.html#link-type-stylesheet" title="rel-stylesheet">external resource links that contribute to
  the styling processing model</a> (i.e. that do not have a <code title="rel-stylesheet"><a href="links.html#link-type-stylesheet">stylesheet</a></code> keyword in their <code title="attr-link-rel"><a href="the-link-element.html#attr-link-rel">rel</a></code> attribute), or for which <a href="links.html#the-link-is-an-alternative-stylesheet">the
  link is an alternative stylesheet</a> but whose <code title="dom-title"><a href="global-attributes.html#dom-title">title</a></code> content attribute is absent or empty,
  must have their <code><a href="infrastructure.html#linkstyle">LinkStyle</a></code> interface's <code title="dom-LinkStyle-sheet"><a href="infrastructure.html#dom-linkstyle-sheet">sheet</a></code> attribute return null.</p>

  <p>Otherwise, the <code><a href="infrastructure.html#linkstyle">LinkStyle</a></code> interface's <code title="dom-LinkStyle-sheet"><a href="infrastructure.html#dom-linkstyle-sheet">sheet</a></code> attribute must return a
  <code><a href="infrastructure.html#stylesheet">StyleSheet</a></code> object with the following properties: <a href="references.html#refsCSSOM">[CSSOM]</a></p>

  <dl><dt>The style sheet type</dt>

   <dd><p>The style sheet type must be the same as the style's specified
   type. For <code><a href="the-style-element.html#the-style-element">style</a></code> elements, this is the same as the
   <code title="attr-style-type"><a href="the-style-element.html#attr-style-type">type</a></code> content attribute's
   value, or <code title="">text/css</code> if that is omitted. For
   <code><a href="the-link-element.html#the-link-element">link</a></code> elements, this is the <a href="urls.html#content-type" title="Content-Type">Content-Type metadata of the specified
   resource</a>.</p></dd>

   <dt>The style sheet location</dt>

   <dd><p>For <code><a href="the-link-element.html#the-link-element">link</a></code> elements, the location must be the
   result of <a href="urls.html#resolve-a-url" title="resolve a url">resolving</a> the
   <a href="urls.html#url">URL</a> given by the element's <code title="attr-link-href"><a href="the-link-element.html#attr-link-href">href</a></code> content attribute, relative to
   the element, or the empty string if that fails. For
   <code><a href="the-style-element.html#the-style-element">style</a></code> elements, there is no location.</p></dd> <!--
   note that this might not match the style sheet URL, if the base URL
   has changed for instance -->

   <dt>The style sheet media</dt>

   <dd><p>The media must be the same as the value of the element's
   <code title="">media</code> content attribute, or the empty string,
   if the attribute is omitted.</p></dd>

   <dt>The style sheet title</dt>

   <dd><p>The title must be the same as the value of the element's
   <code title="dom-title"><a href="global-attributes.html#dom-title">title</a></code> content attribute, if the
   attribute is present and has a non-empty value. If the attribute is
   absent or its value is the empty string, then the style sheet does
   not have a title (it is the empty string). The title is used for
   defining <a href="infrastructure.html#alternative-style-sheet-sets">alternative style sheet sets</a>.</p></dd>

   <dt>The style sheet alternate flag</dt>

   alternative stylesheet</a>. In all other cases, false.</p></dd>

<!--
   <dt>The style sheet disabled flag</dt>
   (not included, because I assume CSSOM will change to not require
   this spec to initialise the value, but will instead initialise it
   based on the other values)
-->

  </dl><p>The same object must be returned each time.</p>

  <p>The <dfn id="dom-linkstyle-disabled" title="dom-LinkStyle-disabled"><code>disabled</code></dfn> IDL
  attribute on <code><a href="the-link-element.html#the-link-element">link</a></code> and <code><a href="the-style-element.html#the-style-element">style</a></code> elements must

  <code><a href="infrastructure.html#linkstyle">LinkStyle</a></code> interface is null. Otherwise, it must return
  the value of the <code><a href="infrastructure.html#stylesheet">StyleSheet</a></code> interface's <code title="dom-stylesheet-disabled"><a href="infrastructure.html#dom-stylesheet-disabled">disabled</a></code> attribute on
  getting, and forward the new value to that same attribute on
  setting.</p>

  <!-- [CSSOM] covers the following: the term "alternative style sheet
  sets", the term "default style sheet set", preferred stylesheets,
  alternative stylesheets, persistent stylesheets, ordering of

  sheets given by HTTP Link: headers, and the alternative style sheet
  API -->

  <p id="alternate-style-sheets">The rules for handling alternative

  <hr><p>Style sheets, whether added by a <code><a href="the-link-element.html#the-link-element">link</a></code> element, a
  <code><a href="the-style-element.html#the-style-element">style</a></code> element, an <code>&lt;?xml-stylesheet&gt;</code> PI,
  an HTTP <code title="http-link">Link:</code> header, or some other
  mechanism, have a <dfn id="style-sheet-ready">style sheet ready</dfn> flag, which is
  initially unset.</p>

  <p>When a style sheet is ready to be applied, its <a href="#style-sheet-ready">style sheet
  ready</a> flag must be set. If the style sheet referenced no
  other resources (e.g. it was an internal style sheet given by a
  <code><a href="the-style-element.html#the-style-element">style</a></code> element with no <code title="">@import</code>
  rules), then the style rules must be synchronously made available to

  script once the <a href="webappapis.html#event-loop">event loop</a> reaches its "update the
  rendering" step.</p>

  <p>A style sheet in the context of the <code><a href="dom.html#document">Document</a></code> of an

  either a <code><a href="the-style-element.html#the-style-element">style</a></code> element or a <code><a href="the-link-element.html#the-link-element">link</a></code> element
  that was an <a href="links.html#link-type-stylesheet" title="rel-stylesheet">external resource link that
  contributes to the styling processing model</a> when the element
  was created by the parser, and the element's style sheet was enabled
  when the element was created by the parser, and the element's
  <a href="#style-sheet-ready">style sheet ready</a> flag is not yet set, and, the last
  time the <a href="webappapis.html#event-loop">event loop</a> reached step 1, the element was
  <a href="infrastructure.html#in-a-document" title="in a document">in that <code>Document</code></a>,
  and the user agent hasn't given up on that particular style sheet
  yet. A user agent may give up on a style sheet at any time.</p>

  <p class="note">Giving up on a style sheet before the style sheet
  loads, if the style sheet eventually does still load, means that the
  script might end up operating with incorrect information. For
  example, if a style sheet sets the color of an element to green, but
  a script that inspects the resulting style is executed before the
  sheet is loaded, the script will find that the element is black (or
  whatever the default color is), and might thus make poor choices
  (e.g. deciding to use black as the color elsewhere on the page,
  instead of green). Implementors have to balance the likelihood of a
  script using incorrect information with the performance impact of
  doing nothing while waiting for a slow network request to
  finish.</p>

       relative order.</li>

      </ol></li>

    </ol></dd>

  </dl><p class="note">All these contortions are required because, for
  historical reasons, the <code><a href="#the-noscript-element">noscript</a></code> element is handled
  differently by the <a href="parsing.html#html-parser">HTML parser</a> based on whether <a href="parsing.html#scripting-flag" title="scripting flag">scripting was enabled or not</a> when the
  parser was invoked.</p>

  <p>The <code><a href="#the-noscript-element">noscript</a></code> element must not be used in <a href="infrastructure.html#xml-documents">XML
  documents</a>.</p>

  <p class="note">The <code><a href="#the-noscript-element">noscript</a></code> element is only effective
  in <a href="syntax.html#syntax">the HTML syntax</a>, it has no effect in <a href="the-xhtml-syntax.html#the-xhtml-syntax">the XHTML
  syntax</a>. This is because the way it works is by essentially
  "turning off" the parser when scripts are enabled, so that the
  contents of the element are treated as pure text and not as real
  elements. XML does not define a mechanism by which to do this.</p>

  <div class="impl">

  <p>The <code><a href="#the-noscript-element">noscript</a></code> element has no other requirements. In
  particular, children of the <code><a href="#the-noscript-element">noscript</a></code> element are not
  exempt from <a href="constraints.html#form-submission-0">form submission</a>, scripting, and so forth,
  even when <a href="webappapis.html#concept-n-script" title="concept-n-script">scripting is enabled</a>
  for the element.</p>

  </div>

  <div class="example">

   <p>In the following example, a <code><a href="#the-noscript-element">noscript</a></code> element is
   used to provide fallback for a script.</p>

   <pre>&lt;form action="calcSquare.php"&gt;
 &lt;p&gt;
  &lt;label for=x&gt;Number&lt;/label&gt;:
  &lt;input id="x" name="x" type="number"&gt;
 &lt;/p&gt;
 &lt;script&gt;
  var x = document.getElementById('x');
  var output = document.createElement('p');
  output.textContent = 'Type a number; it will be squared right then!';
  x.form.appendChild(output);
  x.form.onsubmit = function () { return false; }
  x.oninput = function () {
    var v = x.valueAsNumber;
    output.textContent = v + ' squared is ' + v * v;
  };
 &lt;/script&gt;
 &lt;noscript&gt;
  &lt;input type=submit value="Calculate Square"&gt;
 &lt;/noscript&gt;
&lt;/form&gt;</pre>

   <p>When script is disabled, a button appears to do the calculation
   on the server side. When script is enabled, the value is computed
   on-the-fly instead.</p>

   <p>The <code><a href="#the-noscript-element">noscript</a></code> element is a blunt
   instrument. Sometimes, scripts might be enabled, but for some
   reason the page's script might fail. For this reason, it's
   generally better to avoid using <code><a href="#the-noscript-element">noscript</a></code>, and to
   instead design the script to change the page from being a
   scriptless page to a scripted page on the fly, as in the next
   example:</p>

   <pre>&lt;form action="calcSquare.php"&gt;
 &lt;p&gt;
  &lt;label for=x&gt;Number&lt;/label&gt;:
  &lt;input id="x" name="x" type="number"&gt;
 &lt;/p&gt;
 <strong>&lt;input id="submit" type=submit value="Calculate Square"&gt;</strong>
 &lt;script&gt;
  var x = document.getElementById('x');
  var output = document.createElement('p');
  output.textContent = 'Type a number; it will be squared right then!';
  x.form.appendChild(output);
  x.form.onsubmit = function () { return false; }
  x.oninput = function () {
    var v = x.valueAsNumber;
    output.textContent = v + ' squared is ' + v * v;
  };
<strong>  var submit = document.getElementById('submit');
  submit.parentNode.removeChild(submit);</strong>
 &lt;/script&gt;
&lt;/form&gt;</pre>

   <p>The above technique is also useful in XHTML, since
   <code><a href="#the-noscript-element">noscript</a></code> is not supported in <a href="the-xhtml-syntax.html#the-xhtml-syntax">the XHTML
   syntax</a>.</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-code-element">code</a></code> element <a href="rendering.html#represents">represents</a> a fragment
  of computer code. This could be an XML element name, a filename, a
  computer program, or any other string that a computer would
  recognize.</p>

  <p>Although there is no formal way to indicate the language of
  computer code being marked up, authors who wish to mark
  <code><a href="#the-code-element">code</a></code> elements with the language used, e.g. so that
  syntax highlighting scripts can use the right rules, may do so by
  adding a class prefixed with "<code title="">language-</code>" to
  the element.</p>

  <div class="example">

   <p>The following example shows how the element can be used in a
   paragraph to mark up element names and computer code, including
   punctuation.</p>

   <pre>&lt;p&gt;The &lt;code&gt;code&lt;/code&gt; element represents a fragment of computer
code.&lt;/p&gt;

&lt;p&gt;When you call the &lt;code&gt;activate()&lt;/code&gt; method on the
&lt;code&gt;robotSnowman&lt;/code&gt; object, the eyes glow.&lt;/p&gt;

&lt;p&gt;The example below uses the &lt;code&gt;begin&lt;/code&gt; keyword to indicate
the start of a statement block. It is paired with an &lt;code&gt;end&lt;/code&gt;
keyword, which is followed by the &lt;code&gt;.&lt;/code&gt; punctuation character
(full stop) to indicate the end of the program.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>The following example shows how a block of code could be marked
   up using the <code><a href="the-pre-element.html#the-pre-element">pre</a></code> and <code><a href="#the-code-element">code</a></code> elements.</p>

   <pre>&lt;pre&gt;&lt;code class="language-pascal"&gt;var i: Integer;
begin
   i := 1;
end.&lt;/code&gt;&lt;/pre&gt;</pre>

   <p>A class is used in that example to indicate the language
   used.</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-command-element">command</a></code> element represents a command that the user
  can invoke.</p>

  <p>A command can be explicitly part of a context menu or toolbar,
  using the <code><a href="the-menu-element.html#the-menu-element">menu</a></code> element. It can also be put anywhere
  else on a page, either just to define a keyboard shortcut, or to
  define a command that is then referenced from other
  <code><a href="#the-command-element">command</a></code> elements.</p>

  <p>A <code><a href="#the-command-element">command</a></code> element that uses the
  <code title="attr-command-type"><a href="#attr-command-type">type</a></code>,
  <code title="attr-command-label"><a href="#attr-command-label">label</a></code>,
  <code title="attr-command-icon"><a href="#attr-command-icon">icon</a></code>,
  <code title="attr-command-disabled"><a href="#attr-command-disabled">disabled</a></code>,
  <code title="attr-command-checked"><a href="#attr-command-checked">checked</a></code>,
  <code title="attr-command-radiogroup"><a href="#attr-command-radiogroup">radiogroup</a></code>,
  <!--<code title="attr-command-default">default</code>,--> and
  <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attributes defines a new
  command. A <code><a href="#the-command-element">command</a></code> element that uses the <code title="attr-command-command"><a href="#attr-command-command">command</a></code> <em>attribute</em>
  defines a command by reference to another one. This allows authors
  to define a command once, and set its state (e.g. whether it is
  active or disabled) in one place, and have all references to that
  command in the user interface change at the same time.</p>

  <hr><p>The <dfn id="attr-command-type" title="attr-command-type"><code>type</code></dfn>
  attribute indicates the kind of command: either a normal command
  with an associated action, or a state or option that can be toggled,
  or a selection of one item from a list of items.</p>

  <p>The attribute is an <a href="common-microsyntaxes.html#enumerated-attribute">enumerated attribute</a> with three
  keywords and states. The "<dfn id="attr-command-type-keyword-command" title="attr-command-type-keyword-command"><code>command</code></dfn>"
  keyword maps to the <a href="#attr-command-type-state-command" title="attr-command-type-state-command">Command</a> state, the
  "<dfn id="attr-command-type-keyword-checkbox" title="attr-command-type-keyword-checkbox"><code>checkbox</code></dfn>"

  <p class="note">The distinction between <code title="attr-command-disabled"><a href="#attr-command-disabled">disabled</a></code> and <code title="attr-hidden"><a href="editing.html#the-hidden-attribute">hidden</a></code> is subtle. A command would be
  disabled if, in the same context, it could be enabled if only
  certain aspects of the situation were changed. A command would be
  marked as hidden if, in that situation, the command will never be
  enabled. For example, in the context menu for a water faucet, the
  command "open" might be disabled if the faucet is already open, but
  the command "eat" would be marked hidden since the faucet could
  never be eaten.</p>

  <p>The <dfn id="attr-command-radiogroup" title="attr-command-radiogroup"><code>radiogroup</code></dfn>

  multiline plain text edit control<span class="impl"> for the
  element's <dfn id="concept-textarea-raw-value" title="concept-textarea-raw-value">raw

  control's default value.</p>

  <div class="impl">

  <p>The <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a> of
  a <code><a href="#the-textarea-element">textarea</a></code> control must be initially the empty
  string.</p>

  <p>A newline in a <code><a href="#the-textarea-element">textarea</a></code> element, and in its <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a>, should separate
  paragraphs for the purposes of the Unicode bidirectional algorithm.
  This requirement may be implemented indirectly through the style
  layer. For example, an HTML+CSS user agent could implement these
  requirements by implementing the CSS 'unicode-bidi' property. <a href="references.html#refsBIDI">[BIDI]</a> <a href="references.html#refsCSS">[CSS]</a></p>

  </div>

  <p>The <dfn id="attr-textarea-readonly" title="attr-textarea-readonly"><code>readonly</code></dfn> attribute
  is a <a href="common-microsyntaxes.html#boolean-attribute">boolean attribute</a> used to control whether the text
  can be edited by the user or not.</p>

  <div class="example">

   <p>In this example, a text field is marked read-only because it
   represents a read-only file:</p>

   <pre>Filename: &lt;code&gt;/etc/bash.bashrc&lt;/code&gt;
&lt;textarea name="buffer" readonly&gt;
# System-wide .bashrc file for interactive bash(1) shells.

# To enable the settings / commands in this file for login shells as well,
# this file has to be sourced in /etc/profile.

# If not running interactively, don't do anything

  <p><strong>Constraint validation</strong>: If the <code title="attr-textarea-readonly"><a href="#attr-textarea-readonly">readonly</a></code> attribute is

  <a href="constraints.html#barred-from-constraint-validation">barred from constraint validation</a>.</p>

  <p>A <code><a href="#the-textarea-element">textarea</a></code> element is <dfn id="concept-textarea-mutable" title="concept-textarea-mutable">mutable</dfn> if it is neither
  <a href="attributes-common-to-form-controls.html#concept-fe-disabled" title="concept-fe-disabled">disabled</a> nor has a <code title="attr-textarea-readonly"><a href="#attr-textarea-readonly">readonly</a></code> attribute
  specified.</p>

  <p>When a <code><a href="#the-textarea-element">textarea</a></code> is <a href="#concept-textarea-mutable" title="concept-textarea-mutable">mutable</a>, its <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a> should be
  editable by the user: the user agent should allow the user to edit,
  insert, and remove text, and to insert and remove line breaks in the
  form of "LF" (U+000A) characters. Any time the user causes
  the element's <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw
  value</a> to change, the user agent must <a href="webappapis.html#queue-a-task">queue a

  <code title="event-input">input</code> at the <code><a href="#the-textarea-element">textarea</a></code>
  element. User agents may wait for a suitable break in the user's
  interaction before queuing the task; for example, a user agent could
  wait for the user to have not hit a key for 100ms, so as to only
  fire the event when the user pauses, instead of continuously for
  each keystroke.</p> <!-- same text is present in the <input> section

  <p>A <code><a href="#the-textarea-element">textarea</a></code> element has a <dfn id="concept-textarea-dirty" title="concept-textarea-dirty">dirty value flag</dfn>, which must be
  initially set to false, and must be set to true whenever the user
  interacts with the control in a way that changes the <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a>.</p>

  <p>When the <code><a href="#the-textarea-element">textarea</a></code> element's <code><a href="infrastructure.html#textcontent">textContent</a></code>
  IDL attribute changes value, if the element's <a href="#concept-textarea-dirty" title="concept-textarea-dirty">dirty value flag</a> is false,
  then the element's <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw
  value</a> must be set to the value of the element's
  <code><a href="infrastructure.html#textcontent">textContent</a></code> IDL attribute.</p>

  <p>The <a href="constraints.html#concept-form-reset-control" title="concept-form-reset-control">reset
  algorithm</a> for <code><a href="#the-textarea-element">textarea</a></code> elements is to set the

  <!-- this next bit is also in the <input> Text/Search section -->
  <!-- and something similar is in the session history section -->
  <p>If the element is <a href="#concept-textarea-mutable" title="concept-textarea-mutable">mutable</a>, the user agent
  should allow the user to change the writing direction of the
  element, setting it either to a left-to-right writing direction or a
  right-to-left writing direction. If the user does so, the user agent
  must then run the following steps:</p>

  <ol><li><p>Set the element's <code title="attr-dir"><a href="global-attributes.html#the-dir-attribute">dir</a></code>
   attribute to "<code title="attr-dir-ltr"><a href="global-attributes.html#attr-dir-ltr">ltr</a></code>" if the user
   selected a left-to-right writing direction, and "<code title="attr-dir-rtl"><a href="global-attributes.html#attr-dir-rtl">rtl</a></code>" if the user selected a

  </ol></div>

  <p>The <dfn id="attr-textarea-cols" title="attr-textarea-cols"><code>cols</code></dfn>
  attribute specifies the expected maximum number of characters per
  line. If the <code title="attr-textarea-cols"><a href="#attr-textarea-cols">cols</a></code> attribute
  is specified, its value must be a <a href="common-microsyntaxes.html#valid-non-negative-integer">valid non-negative
  integer</a> greater than zero. <span class="impl">If applying the
  <a href="common-microsyntaxes.html#rules-for-parsing-non-negative-integers">rules for parsing non-negative integers</a> to the

  width</dfn> is that value; otherwise, it is 20.</span></p>

  <div class="impl">

  <p>The user agent may use the <code><a href="#the-textarea-element">textarea</a></code> element's <a href="#attr-textarea-cols-value" title="attr-textarea-cols-value">character width</a> as a hint to
  the user as to how many characters the server prefers per line
  (e.g. for visual user agents by making the width of the control be
  that many characters). In visual renderings, the user agent should
  wrap the user's input in the rendering so that each line is no wider
  than this number of characters.</p>

  </div>

  <p>The <dfn id="attr-textarea-rows" title="attr-textarea-rows"><code>rows</code></dfn>

  <p>The <dfn id="attr-textarea-wrap" title="attr-textarea-wrap"><code>wrap</code></dfn>

  <div class="impl">

  <p>For historical reasons, the element's value is normalised in
  three different ways for three different purposes. The <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a> is the value as
  it was originally set. It is not normalized. The <a href="#concept-textarea-api-value" title="concept-textarea-api-value">API value</a> is the value
  used in the <code title="dom-textarea-value"><a href="#dom-textarea-value">value</a></code> IDL
  attribute. It is normalized so that line breaks use "LF" (U+000A) characters. Finally, there is the form submission <a href="attributes-common-to-form-controls.html#concept-fe-value" title="concept-fe-value">value</a>. It is normalized so that line
  breaks use U+000D CARRIAGE RETURN U+000A LINE FEED (CRLF) character
  pairs, and in addition, if necessary given the element's <code title="attr-textarea-wrap"><a href="#attr-textarea-wrap">wrap</a></code> attribute, additional line
  breaks are inserted to wrap the text at the given width.</p>

  <p>The element's <dfn id="concept-textarea-api-value" title="concept-textarea-api-value">API
  value</dfn> is defined to be the element's <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a> with the
  following transformation applied:</p>

  <ol><li><p>Replace every U+000D CARRIAGE RETURN U+000A LINE FEED (CRLF)
   character pair from the <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a> with a single
   "LF" (U+000A) character.</p></li>

   <li><p>Replace every remaining U+000D CARRIAGE RETURN character from
   the <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a> with
   a single "LF" (U+000A) character.</p></li>

  </ol><p>The element's <a href="attributes-common-to-form-controls.html#concept-fe-value" title="concept-fe-value">value</a> is
  defined to be the element's <a href="#concept-textarea-raw-value" title="concept-textarea-raw-value">raw value</a> with the
  following transformation applied:</p>

  <ol><li><p>Replace every occurrence of a "CR" (U+000D)
   character not followed by a "LF" (U+000A) character, and
   every occurrence of a "LF" (U+000A) character not preceded
   by a "CR" (U+000D) character, by a two-character
   string consisting of a U+000D CARRIAGE RETURN U+000A LINE FEED
   (CRLF) character pair.</p></li>

   <li><p>If the element's <code title="attr-textarea-wrap"><a href="#attr-textarea-wrap">wrap</a></code> attribute is in the <a href="#attr-textarea-wrap-hard-state" title="attr-textarea-wrap-hard-state">Hard</a> state, insert
   U+000D CARRIAGE RETURN U+000A LINE FEED (CRLF) character pairs
   into the string using a UA-defined algorithm so that each line has
   no more than <a href="#attr-textarea-cols-value" title="attr-textarea-cols-value">character
   width</a> characters. For the purposes of this requirement,
   lines are delimited by the start of the string, the end of the
   string, and U+000D CARRIAGE RETURN U+000A LINE FEED (CRLF)
   character pairs.</p></li>

  <p>The <dfn id="attr-textarea-placeholder" title="attr-textarea-placeholder"><code>placeholder</code></dfn>
  attribute represents a <em>short</em> hint (a word or short phrase)
  intended to aid the user with data entry when the control has no

  characters.</p>

  <p>The <code title="attr-textarea-placeholder"><a href="#attr-textarea-placeholder">placeholder</a></code>

  <p class="note">These mechanisms are very similar but subtly
  different: the hint given by the control's <code><a href="the-label-element.html#the-label-element">label</a></code> is
  shown at all times; the short hint given in the <code title="attr-textarea-placeholder"><a href="#attr-textarea-placeholder">placeholder</a></code> attribute is
  shown before the user enters a value; and the hint in the <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute is shown when the user

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-div-element">div</a></code> element has no special meaning at all. It
  <a href="rendering.html#represents">represents</a> its children. It can be used with the <code title="attr-class"><a href="global-attributes.html#classes">class</a></code>, <code title="attr-lang"><a href="global-attributes.html#attr-lang">lang</a></code>, and <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attributes to mark up semantics
  common to a group of consecutive elements.</p>

  <p class="note">Authors are strongly encouraged to view the
  <code><a href="#the-div-element">div</a></code> element as an element of last resort, for when no
  other element is suitable. Use of more appropriate elements instead
  of the <code><a href="#the-div-element">div</a></code> element leads to better accessibility for
  readers and easier maintainability for authors.</p>

  <div class="example">

   <p>For example, a blog post would be marked up using
   <code><a href="the-article-element.html#the-article-element">article</a></code>, a chapter using <code><a href="the-section-element.html#the-section-element">section</a></code>, a
   page's navigation aids using <code><a href="the-nav-element.html#the-nav-element">nav</a></code>, and a group of form
   controls using <code><a href="the-fieldset-element.html#the-fieldset-element">fieldset</a></code>.</p>

   <p>On the other hand, <code><a href="#the-div-element">div</a></code> elements can be useful for
   stylistic purposes or to wrap multiple paragraphs within a section
   that are all to be annotated in a similar way. In the following
   example, we see <code><a href="#the-div-element">div</a></code> elements used as a way to set the
   language of two paragraphs at once, instead of setting the language
   on the two paragraph elements separately:</p>

   <pre>&lt;article lang="en-US"&gt;
 &lt;h1&gt;My use of language and my cats&lt;/h1&gt;
 &lt;p&gt;My cat's behavior hasn't changed much since her absence, except
 that she plays her new physique to the neighbors regularly, in an
 attempt to get pets.&lt;/p&gt;
 &lt;div lang="en-GB"&gt;
  &lt;p&gt;My other cat, coloured black and white, is a sweetie. He followed
  us to the pool today, walking down the pavement with us. Yesterday
  he apparently visited our neighbours. I wonder if he recognises that
  their flat is a mirror image of ours.&lt;/p&gt;
  &lt;p&gt;Hm, I just noticed that in the last paragraph I used British
  English. But I'm supposed to write in American English. So I
  shouldn't say "pavement" or "flat" or "colour"...&lt;/p&gt;
 &lt;/div&gt;
 &lt;p&gt;I should say "sidewalk" and "apartment" and "color"!&lt;/p&gt;
&lt;/article&gt;</pre>

  </div>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-output-element">output</a></code> element <a href="rendering.html#represents">represents</a> the result of a
  calculation.</p>

  <p>The <dfn id="attr-output-for" title="attr-output-for"><code>for</code></dfn> content
  attribute allows an explicit relationship to be made between the
  result of a calculation and the elements that represent the values
  that went into the calculation or that otherwise influenced the
  calculation. The <code title="attr-output-for"><a href="#attr-output-for">for</a></code> attribute,
  if specified, must contain a string consisting of an <a href="common-microsyntaxes.html#unordered-set-of-unique-space-separated-tokens">unordered
  set of unique space-separated tokens</a> that are
  <a href="infrastructure.html#case-sensitive">case-sensitive</a>, each of which must have the value of an
  <a href="infrastructure.html#concept-id" title="concept-id">ID</a> of an element in the same
  <code><a href="dom.html#document">Document</a></code>.</p>

  <p>The <code title="attr-fae-form"><a href="association-of-controls-and-forms.html#attr-fae-form">form</a></code> attribute is used to
  explicitly associate the <code><a href="#the-output-element">output</a></code> element with its
  <a href="association-of-controls-and-forms.html#form-owner">form owner</a>. The <code title="attr-fe-name"><a href="attributes-common-to-form-controls.html#attr-fe-name">name</a></code>
  attribute represents the element's name.</p>

  <div class="impl">

  <p>The element has a <dfn id="concept-output-mode" title="concept-output-mode">value mode
  flag</dfn> which is either <i title="concept-output-mode-value">value</i> or <i title="concept-output-mode-default">default</i>. Initially, the
  <a href="#concept-output-mode" title="concept-output-mode">value mode flag</a> must be set
  to <i title="concept-output-mode-default">default</i>.</p>

  <p>The element also has a <dfn id="concept-output-defaultvalue" title="concept-output-defaultValue">default value</dfn>. Initially,
  the <a href="#concept-output-defaultvalue" title="concept-output-defaultValue">default value</a>
  must be the empty string.</p>

  <p>When the <a href="#concept-output-mode" title="concept-output-mode">value mode flag</a>
  is in mode <i title="concept-output-mode-default">default</i>, the
  contents of the element represent both the value of the element and
  its <a href="#concept-output-defaultvalue" title="concept-output-defaultValue">default
  value</a>. When the <a href="#concept-output-mode" title="concept-output-mode">value mode
  flag</a> is in mode <i title="concept-output-mode-value">value</i>, the contents of the
  element represent the value of the element only, and the <a href="#concept-output-defaultvalue" title="concept-output-defaultValue">default value</a> is only
  accessible using the <code title="dom-output-defaultValue"><a href="#dom-output-defaultvalue">defaultValue</a></code> IDL
  attribute.</p>

  <p>Whenever the element's descendants are changed in any way, if the
  <a href="#concept-output-mode" title="concept-output-mode">value mode flag</a> is in mode
  <i title="concept-output-mode-default">default</i>, the element's
  <a href="#concept-output-defaultvalue" title="concept-output-defaultValue">default value</a> must
  be set to the value of the element's <code><a href="infrastructure.html#textcontent">textContent</a></code> IDL
  attribute.</p>

  <p>The <a href="constraints.html#concept-form-reset-control" title="concept-form-reset-control">reset
  algorithm</a> for <code><a href="#the-output-element">output</a></code> elements is to set the
  element's <a href="#concept-output-mode" title="concept-output-mode">value mode flag</a>
  to <i title="concept-output-mode-default">default</i> and then to
  set the element's <code><a href="infrastructure.html#textcontent">textContent</a></code> IDL attribute to the
  value of the element's <a href="#concept-output-defaultvalue" title="concept-output-defaultValue">default value</a> (thus
  replacing the element's child nodes).</p>

  user interface. The caption can be associated with a specific form
  control<span class="impl">, known as the <code><a href="#the-label-element">label</a></code>
  element's <dfn id="labeled-control">labeled control</dfn></span>, either using <code title="attr-label-for"><a href="#attr-label-for">for</a></code> attribute, or by putting the form
  control inside the <code><a href="#the-label-element">label</a></code> element itself.</p>

  <div class="impl">

  <p>Except where otherwise specified by the following rules, a
  <code><a href="#the-label-element">label</a></code> element has no <a href="#labeled-control">labeled control</a>.</p>

  </div>

  <p>The <dfn id="attr-label-for" title="attr-label-for"><code>for</code></dfn> attribute
  may be specified to indicate a form control with which the caption
  is to be associated. If the attribute is specified, the attribute's
  value must be the <a href="infrastructure.html#concept-id" title="concept-id">ID</a> of a <a href="forms.html#category-label" title="category-label">labelable element</a> in the same
  <code><a href="dom.html#document">Document</a></code> as the <code><a href="#the-label-element">label</a></code> element. <span class="impl">If the attribute is specified and there is an element
  in the <code><a href="dom.html#document">Document</a></code> whose <a href="infrastructure.html#concept-id" title="concept-id">ID</a> is equal to the value of the <code title="attr-label-for"><a href="#attr-label-for">for</a></code> attribute, and the first such
  element is a <a href="forms.html#category-label" title="category-label">labelable element</a>,
  then that element is the <code><a href="#the-label-element">label</a></code> element's <a href="#labeled-control">labeled
  control</a>.</span></p>

  <div class="impl">

  <p>If the <code title="attr-label-for"><a href="#attr-label-for">for</a></code> attribute is not
  specified, but the <code><a href="#the-label-element">label</a></code> element has a <a href="forms.html#category-label" title="category-label">labelable element</a> descendant, then the
  first such descendant in <a href="infrastructure.html#tree-order">tree order</a> is the
  <code><a href="#the-label-element">label</a></code> element's <a href="#labeled-control">labeled control</a>.</p>

  <p>The <code><a href="#the-label-element">label</a></code> element's exact default presentation and
  behavior, in particular what its <a href="content-models.html#activation-behavior">activation behavior</a>
  might be, if anything, should match the platform's label behavior.
  The <a href="content-models.html#activation-behavior">activation behavior</a> of a <code><a href="#the-label-element">label</a></code> element
  for events targetted at <a href="content-models.html#interactive-content-0">interactive content</a> descendants
  of a <code><a href="#the-label-element">label</a></code> element, and any descendants of those
  <a href="content-models.html#interactive-content-0">interactive content</a> descendants, must be to do
  nothing.</p>

  <!-- activation behaviour need not be dependent on whether the
  labeled control is being rendered:
   http://software.hixie.ch/utilities/js/live-dom-viewer/saved/371
  -->

  <div class="example">

   <p>For example, on platforms where clicking a checkbox label checks
   the checkbox, clicking the <code><a href="#the-label-element">label</a></code> in the following
   snippet could trigger the user agent to <a href="content-models.html#run-synthetic-click-activation-steps">run synthetic click
   activation steps</a> on the <code><a href="the-input-element.html#the-input-element">input</a></code> element, as if
   the element itself had been triggered by the user:</p>

   <pre>&lt;label&gt;&lt;input type=checkbox name=lost&gt; Lost&lt;/label&gt;</pre>

   <p>On other platforms, the behavior might be just to focus the
   control, or do nothing.</p>

  </div>

  </div>

  <p>The <code title="attr-fae-form"><a href="association-of-controls-and-forms.html#attr-fae-form">form</a></code> attribute is used to
  explicitly associate the <code><a href="#the-label-element">label</a></code> element with its
  <a href="association-of-controls-and-forms.html#form-owner">form owner</a>.</p>

  <div class="example">

   <p>The following example shows three form controls each with a
   label, two of which have small text showing the right format for
   users to use.</p>

   <pre>&lt;p&gt;&lt;label&gt;Full name: &lt;input name=fn&gt; &lt;small&gt;Format: First Last&lt;/small&gt;&lt;/label&gt;&lt;/p&gt;

  (<code><a href="the-dt-element.html#the-dt-element">dt</a></code> elements) followed by one or more values
  (<code><a href="the-dd-element.html#the-dd-element">dd</a></code> elements). Within a single <code><a href="#the-dl-element">dl</a></code> element,
  there should not be more than one <code><a href="the-dt-element.html#the-dt-element">dt</a></code> element for each
  name.</p>

  <p>Name-value groups may be terms and definitions, metadata topics
  and values, questions and answers, or any other groups of name-value
  data.</p>

  <p>The values within a group are alternatives; multiple paragraphs
  forming part of the same value must all be given within the same
  <code><a href="the-dd-element.html#the-dd-element">dd</a></code> element.</p>

  <p>The order of the list of groups, and of the names and values
  within each group, may be significant.</p>

  <div class="impl">

  <p>If a <code><a href="#the-dl-element">dl</a></code> element is empty, it contains no groups.</p>

  <p>If a <code><a href="#the-dl-element">dl</a></code> element has one or more non-<a href="content-models.html#inter-element-whitespace" title="inter-element whitespace">whitespace</a> <code><a href="infrastructure.html#text-0">Text</a></code>
  node children, or has child elements that are neither
  <code><a href="the-dt-element.html#the-dt-element">dt</a></code> nor <code><a href="the-dd-element.html#the-dd-element">dd</a></code> elements, all such
  <code><a href="infrastructure.html#text-0">Text</a></code> nodes and elements, as well as their descendants
  (including any <code><a href="the-dt-element.html#the-dt-element">dt</a></code> or <code><a href="the-dd-element.html#the-dd-element">dd</a></code> elements), do not
  form part of any groups in that <code><a href="#the-dl-element">dl</a></code>.</p>

  <p>If a <code><a href="#the-dl-element">dl</a></code> element has one or more <code><a href="the-dt-element.html#the-dt-element">dt</a></code>
  element children but no <code><a href="the-dd-element.html#the-dd-element">dd</a></code> element children, then it
  consists of one group with names but no values.</p>

  <p>If a <code><a href="#the-dl-element">dl</a></code> element has one or more <code><a href="the-dd-element.html#the-dd-element">dd</a></code>
  element children but no <code><a href="the-dt-element.html#the-dt-element">dt</a></code> element children, then it
  consists of one group with values but no names.</p>

  <p>If a <code><a href="#the-dl-element">dl</a></code> element's first <code><a href="the-dt-element.html#the-dt-element">dt</a></code> or
  <code><a href="the-dd-element.html#the-dd-element">dd</a></code> element child is a <code><a href="the-dd-element.html#the-dd-element">dd</a></code> element, then the
  first group has no associated name.</p>

  <p>If a <code><a href="#the-dl-element">dl</a></code> element's last <code><a href="the-dt-element.html#the-dt-element">dt</a></code> or
  <code><a href="the-dd-element.html#the-dd-element">dd</a></code> element child is a <code><a href="the-dt-element.html#the-dt-element">dt</a></code> element, then the
  last group has no associated value.</p>

  <p class="note">When a <code><a href="#the-dl-element">dl</a></code> element doesn't match its
  content model, it is often due to accidentally using <code><a href="the-dd-element.html#the-dd-element">dd</a></code>
  elements in the place of <code><a href="the-dt-element.html#the-dt-element">dt</a></code> elements and vice
  versa. Conformance checkers can spot such mistakes and might be able
  to advise authors how to correctly use the markup.</p>

  </div>

  <div class="example">
   <p>In the following example, one entry ("Authors") is linked to two
   values ("John" and "Luke").</p>
   <pre>&lt;dl&gt;
 &lt;dt&gt; Authors
 &lt;dd&gt; John
 &lt;dd&gt; Luke
 &lt;dt&gt; Editor
 &lt;dd&gt; Frank
&lt;/dl&gt;</pre>
  </div>

  <div class="example">
   <p>In the following example, one definition is linked to two
   terms.</p>
   <pre>&lt;dl&gt;
 &lt;dt lang="en-US"&gt; &lt;dfn&gt;color&lt;/dfn&gt; &lt;/dt&gt;
 &lt;dt lang="en-GB"&gt; &lt;dfn&gt;colour&lt;/dfn&gt; &lt;/dt&gt;
 &lt;dd&gt; A sensation which (in humans) derives from the ability of
 the fine structure of the eye to distinguish three differently
 filtered analyses of a view. &lt;/dd&gt;
&lt;/dl&gt;</pre>
  </div>

  <div class="example">
   <p>The following example illustrates the use of the <code><a href="#the-dl-element">dl</a></code>
   element to mark up metadata of sorts. At the end of the example,
   one group has two metadata labels ("Authors" and "Editors") and two
   values ("Robert Rothman" and "Daniel Jackson").</p>

  <div class="example">

   <p>The following example shows the <code><a href="#the-dl-element">dl</a></code> element used to
   give a set of instructions. The order of the instructions here is
   important (in the other examples, the order of the blocks was not
   important).</p>

   <pre>&lt;p&gt;Determine the victory points as follows (use the
first matching case):&lt;/p&gt;
&lt;dl&gt;
 &lt;dt&gt; If you have exactly five gold coins &lt;/dt&gt;
 &lt;dd&gt; You get five victory points &lt;/dd&gt;
 &lt;dt&gt; If you have one or more gold coins, and you have one or more silver coins &lt;/dt&gt;
 &lt;dd&gt; You get two victory points &lt;/dd&gt;
 &lt;dt&gt; If you have one or more silver coins &lt;/dt&gt;
 &lt;dd&gt; You get one victory point &lt;/dd&gt;
 &lt;dt&gt; Otherwise &lt;/dt&gt;
 &lt;dd&gt; You get no victory points &lt;/dd&gt;

  <div class="example">
   <p>The following snippet shows a <code><a href="#the-dl-element">dl</a></code> element being used

  <div class="example">

   <p>The following example shows how a <code><a href="#the-select-element">select</a></code> element
   can be used to offer the user with a set of options from which the
   user can select a single option. The default option is
   preselected.</p>

   <pre>&lt;p&gt;
 &lt;label for="unittype"&gt;Select unit type:&lt;/label&gt;
 &lt;select id="unittype" name="unittype"&gt;
  &lt;option value="1"&gt; Miner &lt;/option&gt;
  &lt;option value="2"&gt; Puffer &lt;/option&gt;
  &lt;option value="3" selected&gt; Snipey &lt;/option&gt;
  &lt;option value="4"&gt; Max &lt;/option&gt;
  &lt;option value="5"&gt; Firebot &lt;/option&gt;
 &lt;/select&gt;
&lt;/p&gt;</pre>

   <p>When there is no default option, a placeholder can be used
   instead:</p>

   <pre>&lt;select name="unittype" <strong>required</strong>&gt;
 <strong>&lt;option value=""&gt; Select unit type &lt;/option&gt;</strong>
 &lt;option value="1"&gt; Miner &lt;/option&gt;
 &lt;option value="2"&gt; Puffer &lt;/option&gt;
 &lt;option value="3"&gt; Snipey &lt;/option&gt;
 &lt;option value="4"&gt; Max &lt;/option&gt;
 &lt;option value="5"&gt; Firebot &lt;/option&gt;
&lt;/select&gt;</pre>

  </div>

  <div class="example">

   <p>Here, the user is offered a set of options from which he can
   select any number. By default, all five options are selected.</p>

   <pre>&lt;p&gt;
 &lt;label for="allowedunits"&gt;Select unit types to enable on this map:&lt;/label&gt;
 &lt;select id="allowedunits" name="allowedunits" multiple&gt;
  &lt;option value="1" selected&gt; Miner &lt;/option&gt;
  &lt;option value="2" selected&gt; Puffer &lt;/option&gt;

  &lt;option value="5" selected&gt; Firebot &lt;/option&gt;
 &lt;/select&gt;
&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>Sometimes, a user has to select one or more items. This example
   shows such an interface.</p>

   <pre>&lt;p&gt;Select the songs from that you would like on your Act II Mix Tape:&lt;/p&gt;

  <h4 id="spelling-and-grammar-checking"><span class="secno">7.6.5 </span>Spelling and grammar checking</h4>

  <div class="impl">

  <p>User agents can support the checking of spelling and grammar of
  editable text, either in form controls (such as the value of
  <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> elements), or in elements in an <a href="#editing-host">editing
  host</a> (e.g. using <code title="attr-contenteditable"><a href="editing.html#attr-contenteditable">contenteditable</a></code>).</p>

  <p>For each element, user agents must establish a <dfn id="concept-spellcheck-default" title="concept-spellcheck-default">default behavior</dfn>, either
  through defaults or through preferences expressed by the user. There
  are three possible default behaviors for each element:</p>

  <dl><dt><dfn id="concept-spellcheck-default-true" title="concept-spellcheck-default-true">true-by-default</dfn>

   </dt><dd>The element will be checked for spelling and grammar if its

  <p>The <dfn id="attr-spellcheck" title="attr-spellcheck"><code>spellcheck</code></dfn>
  attribute is an <a href="common-microsyntaxes.html#enumerated-attribute">enumerated attribute</a> whose keywords are
  the empty string, <code title="">true</code> and <code title="">false</code>. The empty string and the <code title="">true</code> keyword map to the <i>true</i> state. The <code title="">false</code> keyword maps to the <i>false</i> state. In
  addition, there is a third state, the <i>default</i> state, which is
  the <i>missing value default</i> (and the <i>invalid value
  default</i>).</p>

  <p class="note">The <i>true</i> state indicates that the element is
  to have its spelling and grammar checked. The <i>default</i> state
  indicates that the element is to act according to a default
  behavior, possibly based on the parent element's own <code title="attr-spellcheck"><a href="#attr-spellcheck">spellcheck</a></code> state, as defined below.
  The <i>false</i> state indicates that the element is not to be
  checked.</p>

  <p>The <dfn id="dom-spellcheck" title="dom-spellcheck"><code>spellcheck</code></dfn> IDL
  attribute, on getting, must return true if the element's <code title="attr-spellcheck"><a href="#attr-spellcheck">spellcheck</a></code> content attribute is in
  the <i>true</i> state, or if the element's <code title="attr-spellcheck"><a href="#attr-spellcheck">spellcheck</a></code> content attribute is in

  and the element's parent element's <code title="dom-spellcheck"><a href="#dom-spellcheck">spellcheck</a></code> IDL attribute would return
  true; otherwise, if none of those conditions applies, then the
  attribute must instead return false.</p>

  <p class="note">The <code title="dom-spellcheck"><a href="#dom-spellcheck">spellcheck</a></code>
  IDL attribute is not affected by user preferences that override the

  <p>On setting, if the new value is true, then the element's <code title="attr-spellcheck"><a href="#attr-spellcheck">spellcheck</a></code> content attribute must be
  set to the literal string "<code title="">true</code>", otherwise it
  must be set to the literal string "<code title="">false</code>".

  </p><hr><p>User agents must only consider the following pieces of text as
  checkable for the purposes of this feature:</p>

  <ul><li>The value of <code><a href="the-input-element.html#the-input-element">input</a></code> elements to which the <code title="attr-input-readonly"><a href="common-input-element-attributes.html#attr-input-readonly">readonly</a></code> attribute applies,
   whose <code title="attr-input-type"><a href="the-input-element.html#attr-input-type">type</a></code> attributes are not
   in the <a href="states-of-the-type-attribute.html#password-state-(type=password)" title="attr-input-type-password">Password</a>
   state, and that are not <i title="concept-input-immutable"><a href="the-input-element.html#concept-input-immutable">immutable</a></i> (i.e. that do not
   have the <code title="attr-input-readonly"><a href="common-input-element-attributes.html#attr-input-readonly">readonly</a></code>
   attribute specified and that are not <a href="attributes-common-to-form-controls.html#concept-fe-disabled" title="concept-fe-disabled">disabled</a>).</li>

   <li>The value of <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> elements that do not have a
   <code title="attr-textarea-readonly"><a href="the-textarea-element.html#attr-textarea-readonly">readonly</a></code> attribute and
   that are not <a href="attributes-common-to-form-controls.html#concept-fe-disabled" title="concept-fe-disabled">disabled</a>.</li>

   <li>Text in <code><a href="infrastructure.html#text-0">Text</a></code> nodes that are
   children of <a href="#editing-host" title="editing host">editing hosts</a> or
   <a href="#editable">editable</a> elements.</li>

   <li>Text in attributes of <a href="#editable">editable</a> elements.</li>

  </ul><p>For text that is part of a <code><a href="infrastructure.html#text-0">Text</a></code> node, the element
  with which the text is associated is the element that is the
  immediate parent of the first character of the word, sentence, or
  other piece of text. For text in attributes, it is the attribute's
  element. For the values of <code><a href="the-input-element.html#the-input-element">input</a></code> and
  <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> elements, it is the element itself.</p>

  <p>To determine if a word, sentence, or other piece of text in an
  applicable element (as defined above) is to have spelling- and/or
  grammar-checking enabled, the UA must use the following
  algorithm:</p>

  <ol><!-- user override --><li>If the user has disabled the checking for this text, then the
   checking is disabled.</li>

   <li>Otherwise, if the user has forced the checking for this text to
   always be enabled, then the checking is enabled.</li>

   <!-- content attribute: on, off -->

   <li>Otherwise, if the element with which the text is associated has
   a <code title="attr-spellcheck"><a href="#attr-spellcheck">spellcheck</a></code> content
   attribute, then: if that attribute is in the <i>true</i> state,
   then checking is enabled; otherwise, if that attribute is in the
   <i>false</i> state, then checking is disabled.</li>

   <!-- inherit, if there is one to inherit from -->

   <li>Otherwise, if there is an ancestor element with a <code title="attr-spellcheck"><a href="#attr-spellcheck">spellcheck</a></code> content attribute that is
   not in the <i>default</i> state, then: if the nearest such
   ancestor's <code title="attr-spellcheck"><a href="#attr-spellcheck">spellcheck</a></code> content
   attribute is in the <i>true</i> state, then checking is enabled;
   otherwise, checking is disabled.</li>

   <!-- default -->

   <li>Otherwise, if the element's <a href="#concept-spellcheck-default" title="concept-spellcheck-default">default behavior</a> is <a href="#concept-spellcheck-default-true" title="concept-spellcheck-default-true">true-by-default</a>,
   then checking is enabled.</li>

   <li>Otherwise, if the element's <a href="#concept-spellcheck-default" title="concept-spellcheck-default">default behavior</a> is <a href="#concept-spellcheck-default-false" title="concept-spellcheck-default-false">false-by-default</a>,
   then checking is disabled.</li>

   <!-- default inheritance -->

   <li>Otherwise, if the element's parent element has <em>its</em>
   checking enabled, then checking is enabled.</li>

   <li>Otherwise, checking is disabled.</li>

  </ol><p>If the checking is enabled for a word/sentence/text, the user
  agent should indicate spelling and/or grammar errors in that
  text. User agents should take into account the other semantics given
  in the document when suggesting spelling and grammar
  corrections. User agents may use the language of the element to
  determine what spelling and grammar rules to use, or may use the
  user's preferred language settings. UAs should use
  <code><a href="the-input-element.html#the-input-element">input</a></code> element attributes such as <code title="attr-input-pattern"><a href="common-input-element-attributes.html#attr-input-pattern">pattern</a></code> to ensure that the
  resulting value is valid, where possible.</p>

  <p>If checking is disabled, the user agent should not indicate
  spelling or grammar errors for that text.</p>

  <div class="example">

   <p>The element with ID "a" in the following example would be the
   one used to determine if the word "Hello" is checked for spelling
   errors. In this example, it would not be.</p>

   <pre>&lt;div contenteditable="true"&gt;
 &lt;span spellcheck="false" id="a"&gt;Hell&lt;/span&gt;&lt;em&gt;o!&lt;/em&gt;
&lt;/div&gt;</pre>

   <p>The element with ID "b" in the following example would have
   checking enabled (the leading space character in the attribute's
   value on the <code><a href="the-input-element.html#the-input-element">input</a></code> element causes the attribute to be
   ignored, so the ancestor's value is used instead, regardless of the
   default).</p>

   <pre>&lt;p spellcheck="true"&gt;
 &lt;label&gt;Name: &lt;input spellcheck=" false" id="b"&gt;&lt;/label&gt;
&lt;/p&gt;</pre>

  </div>

  </div>

  <p class="note">This specification does not define the user
  interface for spelling and grammar checkers. A user agent could
  offer on-demand checking, could perform continuous checking while
  the checking is enabled, or could use other interfaces.</p>

  <p class="note">This section only describes the rules for XML
  resources. Rules for <code><a href="iana.html#text/html">text/html</a></code> resources are discussed
  in the section above entitled "<a href="syntax.html#syntax">The HTML syntax</a>".</p>


  <div class="impl">

  <h3 id="writing-xhtml-documents"><span class="secno">9.1 </span>Writing XHTML documents</h3>

  </div>

  <p>The syntax for using HTML with XML, whether in XHTML documents or
  embedded in other XML documents, is defined in the XML and
  Namespaces in XML specifications. <a href="references.html#refsXML">[XML]</a> <a href="references.html#refsXMLNS">[XMLNS]</a></p>

  <p>This specification does not define any syntax-level requirements
  beyond those defined for XML proper.</p>

  <p>XML documents may contain a <code>DOCTYPE</code> if desired, but
  this is not required to conform to this specification. This
  specification does not define a public or system identifier, nor
  provide a format DTD.</p>

  <p class="note">According to the XML specification, XML processors
  are not guaranteed to process the external DTD subset referenced in
  the DOCTYPE. This means, for example, that using entity references
  for characters in XHTML documents is unsafe if they are defined in
  an external file (except for <code title="">&amp;lt;</code>, <code title="">&amp;gt;</code>, <code title="">&amp;amp;</code>, <code title="">&amp;quot;</code> and <code title="">&amp;apos;</code>).</p>


  <div class="impl">

  <h3 id="parsing-xhtml-documents"><span class="secno">9.2 </span>Parsing XHTML documents</h3>

  <p>This section describes the relationship between XML and the DOM,
  with a particular emphasis on how this interacts with HTML.</p>

  <p>An <dfn id="xml-parser">XML parser</dfn>, for the purposes of this specification,
  is a construct that follows the rules given in the XML specification
  to map a string of bytes or characters into a <code><a href="dom.html#document">Document</a></code>
  object.</p>

  <p>An <a href="#xml-parser">XML parser</a> is either associated with a
  <code><a href="dom.html#document">Document</a></code> object when it is created, or creates one
  implicitly.</p>

  <p>This <code><a href="dom.html#document">Document</a></code> must then be populated with DOM nodes
  that represent the tree structure of the input passed to the parser,
  as defined by the XML specification, the Namespaces in XML
  specification, and the DOM Core specification. DOM mutation events
  must not fire for the operations that the <a href="#xml-parser">XML parser</a>
  performs on the <code><a href="dom.html#document">Document</a></code>'s tree, but the user agent
  must act as if elements and attributes were individually appended
  and set respectively so as to trigger rules in this specification
  regarding what happens when an element is inserted into a document
  or has its attributes set. <a href="references.html#refsXML">[XML]</a> <a href="references.html#refsXMLNS">[XMLNS]</a> <a href="references.html#refsDOMCORE">[DOMCORE]</a>
  <a href="references.html#refsDOMEVENTS">[DOMEVENTS]</a></p>

  <p>Between the time an element's start tag is parsed and the time
  either the element's end tag is parsed or the parser detects a
  well-formedness error, the user agent must act as if the element was
  in a <a href="parsing.html#stack-of-open-elements">stack of open elements</a>.</p>

  <p class="note">This is used by the <code><a href="the-object-element.html#the-object-element">object</a></code> element to
  avoid instantiating plugins before the <code><a href="the-param-element.html#the-param-element">param</a></code> element
  children have been parsed.</p>

  <p>This specification provides the following additional information

  <p>The <dfn id="xml-fragment-serialization-algorithm">XML fragment serialization algorithm</dfn> for a
  <code><a href="dom.html#document">Document</a></code> or <code><a href="infrastructure.html#element">Element</a></code> node either returns a
  fragment of XML that represents that node or throws an
  exception.</p>

  <p>For <code><a href="dom.html#document">Document</a></code>s, the algorithm must return a string in
  the form of a <a href="http://www.w3.org/TR/xml/#sec-well-formed">document
  entity</a>, if none of the error cases below apply.</p>

  <p>For <code><a href="infrastructure.html#element">Element</a></code>s, the algorithm must return a string in
  the form of an <a href="http://www.w3.org/TR/xml/#wf-entities">internal general parsed
  entity</a>, if none of the error cases below apply.</p>

  <p>In both cases, the string returned must be XML
  namespace-well-formed and must be an isomorphic serialization of all
  of that node's child nodes, in <a href="infrastructure.html#tree-order">tree order</a>. User agents
  may adjust prefixes and namespace declarations in the serialization
  (and indeed might be forced to do so in some cases to obtain
  namespace-well-formed XML). User agents may use a combination of
  regular text and character references to represent
  <code><a href="infrastructure.html#text-0">Text</a></code> nodes in the DOM.</p>

  <p>For <code><a href="infrastructure.html#element">Element</a></code>s, if any of the elements in the
  serialization are in no namespace, the default namespace in scope
  for those elements must be explicitly declared as the empty
  string.<!-- because otherwise round-tripping might break since it'll
  pick up the surrounding default ns when setting --> (This doesn't
  apply in the <code><a href="dom.html#document">Document</a></code> case.) <a href="references.html#refsXML">[XML]</a> <a href="references.html#refsXMLNS">[XMLNS]</a></p>

  <p>For the purposes of this section, an internal general parsed
  entity is considered XML namespace-well-formed if a document
  consisting of an element with no namespace declarations whose
  contents are the internal general parsed entity would itself be XML
  namespace-well-formed.</p>

  <p>If any of the following error cases are found in the DOM subtree
  being serialized, then the algorithm must throw an
  <code><a href="infrastructure.html#invalidstateerror">InvalidStateError</a></code> exception instead of returning a
  string:</p>

  <ul><li>A <code><a href="dom.html#document">Document</a></code> node with no child element nodes.</li>

   <li>A <code><a href="infrastructure.html#documenttype">DocumentType</a></code> node that has an external subset
   public identifier that contains characters that are not matched by
   the XML <code title="">PubidChar</code> production. <a href="references.html#refsXML">[XML]</a></li>

   <li>A <code><a href="infrastructure.html#documenttype">DocumentType</a></code> node that has an external subset
   system identifier that contains both a """ (U+0022)
   and a "'" (U+0027) or that contains characters that are
   not matched by the XML <code title="">Char</code> production. <a href="references.html#refsXML">[XML]</a></li>

   <li>A node with a <!--prefix or--> local name containing a ":" (U+003A).</li> <!--(prefixes can get adjusted, so this isn't an
   excuse) -->

   <li>A node with a <!--prefix or--> local name that does not match
   the XML <code title="">Name</code> production. <a href="references.html#refsXML">[XML]</a></li> <!--(again, prefixes can get
   adjusted, so this isn't an excuse) -->

   <li>An <code><a href="infrastructure.html#attr">Attr</a></code> node with no namespace whose local name is
   the lowercase string "<code title="">xmlns</code>". <a href="references.html#refsXMLNS">[XMLNS]</a></li>

   <li>An <code><a href="infrastructure.html#element">Element</a></code> node with two or more attributes with
   the same local name and namespace.</li>

   <li>An <code><a href="infrastructure.html#attr">Attr</a></code> node, <code><a href="infrastructure.html#text-0">Text</a></code> node,
   <code><a href="infrastructure.html#comment-0">Comment</a></code> node, or <code><a href="infrastructure.html#processinginstruction">ProcessingInstruction</a></code>
   node whose data contains characters that are not matched by the XML
   <code title="">Char</code> production. <a href="references.html#refsXML">[XML]</a></li>

   <li>A <code><a href="infrastructure.html#comment-0">Comment</a></code> node whose data contains two adjacent
   "-" (U+002D) characters or ends with such a
   character.</li>

   <li>A <code><a href="infrastructure.html#processinginstruction">ProcessingInstruction</a></code> node whose target name is
   an <a href="infrastructure.html#ascii-case-insensitive">ASCII case-insensitive</a> match for the string "<code title="">xml</code>".</li>

   <li>A <code><a href="infrastructure.html#processinginstruction">ProcessingInstruction</a></code> node whose target name
   contains a ":" (U+003A).</li>

   <li>A <code><a href="infrastructure.html#processinginstruction">ProcessingInstruction</a></code> node whose data contains
   the string "<code title="">?&gt;</code>".</li>

  </ul><p class="note">These are the only ways to make a DOM
  unserializable. The DOM enforces all the other XML constraints; for
  example, trying to append two elements to a <code><a href="dom.html#document">Document</a></code>
  node will throw a <code><a href="infrastructure.html#hierarchyrequesterror">HierarchyRequestError</a></code> exception.</p>



  <h3 id="parsing-xhtml-fragments"><span class="secno">9.4 </span>Parsing XHTML fragments</h3>

  <p>The <dfn id="xml-fragment-parsing-algorithm">XML fragment parsing algorithm</dfn> either returns a
  <code><a href="dom.html#document">Document</a></code> or throws a <code><a href="infrastructure.html#syntaxerror">SyntaxError</a></code> exception.
  Given a string <var title="">input</var> and an optional context
  element <var title="concept-frag-parse-context"><a href="the-end.html#concept-frag-parse-context">context</a></var>, the
  algorithm is as follows:</p>

  <ol><li>

    <p>Create a new <a href="#xml-parser">XML parser</a>.</p>

   </li>

   <li>

    <p>If there is a <var title="concept-frag-parse-context"><a href="the-end.html#concept-frag-parse-context">context</a></var> element,
    <a href="#feed-the-parser">feed the parser</a> just created the string corresponding
    to the start tag of that element, declaring all the namespace
    prefixes that are in scope on that element in the DOM, as well as
    declaring the default namespace (if any) that is in scope on that
    element in the DOM.</p>

    <p>A namespace prefix is in scope if the DOM Core <code title="">lookupNamespaceURI()</code> method on the element would
    return a non-null value for that prefix.</p>

    <p>The default namespace is the namespace for which the DOM Core
    <code title="">isDefaultNamespace()</code> method on the element
    would return true.</p>

    <p class="note">If there is a <var title="concept-frag-parse-context"><a href="the-end.html#concept-frag-parse-context">context</a></var> element, no <code title="">DOCTYPE</code> is passed to the parser, and therefore no
    external subset is referenced, and therefore no entities will be
    recognized.</p>

   </li>

   <li>

    <p><a href="#feed-the-parser">Feed the parser</a> just created the string <var title="">input</var>.</p>

   </li>

   <li>

    <p>If there is a <var title="concept-frag-parse-context"><a href="the-end.html#concept-frag-parse-context">context</a></var> element,
    <a href="#feed-the-parser">feed the parser</a> just created the string corresponding
    to the end tag of that element.</p>

   </li>

   <li>

    <p>If there is an XML well-formedness or XML namespace
    well-formedness error, then throw a <code><a href="infrastructure.html#syntaxerror">SyntaxError</a></code>
    exception and abort these steps.</p>

   </li>

   <li>

    <p>If there is a <var title="concept-frag-parse-context"><a href="the-end.html#concept-frag-parse-context">context</a></var> element, and the
    root element of the resulting <code><a href="dom.html#document">Document</a></code> has any
    sibling nodes, then throw a <code><a href="infrastructure.html#syntaxerror">SyntaxError</a></code> exception and
    abort these steps.</p>

    <!-- http://software.hixie.ch/utilities/js/live-dom-viewer/saved/1443 -->

   </li>

   <li>

    <p>If there is a <var title="concept-frag-parse-context"><a href="the-end.html#concept-frag-parse-context">context</a></var> element, then
    return the child nodes of the root element of the resulting
    <code><a href="dom.html#document">Document</a></code>, in <a href="infrastructure.html#tree-order">tree order</a>.</p>

    <p>Otherwise, return the children of the <code><a href="dom.html#document">Document</a></code>
    object, in <a href="infrastructure.html#tree-order">tree order</a>.</p>

   </li>

  <p>Content may be provided inside the <code><a href="#the-video-element">video</a></code>
  element<span class="impl">. User agents should not show this content
  to the user</span>; it is intended for older Web browsers which do
  not support <code><a href="#the-video-element">video</a></code>, so that legacy video plugins can be
  tried, or to show text to the users of these older browsers informing
  them of how to access the video contents.</p>

  <p class="note">In particular, this content is not intended to
  address accessibility concerns. To make video content accessible to
  the partially sighted, the blind, the hard-of-hearing, the deaf, and
  those with other physical or cognitive disabilities, a variety of
  features are available. Captions can be provided, either embedded in
  the video stream or as external files using the <code><a href="the-track-element.html#the-track-element">track</a></code>
  element. Sign-language tracks can be provided, again either embedded
  in the video stream or by synchronizing multiple <code><a href="#the-video-element">video</a></code>
  elements using the <code title="attr-media-mediagroup"><a href="media-elements.html#attr-media-mediagroup">mediagroup</a></code> attribute or a
  <code><a href="media-elements.html#mediacontroller">MediaController</a></code> object. Audio descriptions can be
  provided, either as a separate track embedded in the video stream,
  or a separate audio track in an <code><a href="the-audio-element.html#the-audio-element">audio</a></code> element <a href="media-elements.html#slaved-media-elements" title="slaved media elements">slaved</a> to the same controller
  as the <code><a href="#the-video-element">video</a></code> element(s), or in text form using a
<!--FORK-->
  caption file
<!--FORK-->
  referenced using the <code><a href="the-track-element.html#the-track-element">track</a></code> element and synthesized into
  speech by the user agent. WebVTT can also be used to provide chapter
  titles. For users who would rather not use a media element at all,
  transcripts or other textual alternatives can be provided by simply
  linking to them in the prose near the <code><a href="#the-video-element">video</a></code> element.

  <p>The <dfn id="attr-video-poster" title="attr-video-poster"><code>poster</code></dfn>

  not define how to apply the aspect ratio to the video data's

  must apply the ratio by increasing one dimension and leaving the
  other unchanged.</p>

  <p>The <dfn id="dom-video-videowidth" title="dom-video-videoWidth"><code>videoWidth</code></dfn> IDL

  <p>In the absence of style rules to the contrary, video content
  should be rendered inside the element's playback area such that the

  content's aspect ratio being preserved. Thus, if the aspect ratio of
  the playback area does not match the aspect ratio of the video, the
  video will be shown letterboxed or pillarboxed. Areas of the
  element's playback area that do not contain the video represent
  nothing.</p>

  <p class="note">In user agents that implement CSS, the above

  <hr><p>User agents should provide controls to enable or disable the

  additional data associated with the video stream, though such
  features should, again, not interfere with the page's normal
  rendering.</p>

  <p>User agents may allow users to view the video content in manners
  more suitable to the user (e.g. full-screen or in an independent
  resizable window). As for the other user interface features,

  rendering unless the user agent is <a href="media-elements.html#expose-a-user-interface-to-the-user" title="expose a user
  interface to the user">exposing a user interface</a>. In such an

  interfaces visible, with, e.g., play, pause, seeking, and volume
  controls, even if the <code title="attr-media-controls"><a href="media-elements.html#attr-media-controls">controls</a></code> attribute is absent.</p>

  <p>User agents may allow video playback to affect system features
  that could interfere with the user's experience; for example, user
  agents could disable screensavers while video playback is in
  progress.</p>

  (Unfortunately, for historical reasons, not rendering borders on
  tables is a common default.)</p>

  <p>In speech media, table cells can be distinguished by reporting
  the corresponding headers before reading the cell's contents, and by
  allowing users to navigate the table in a grid fashion, rather than
  serializing the entire contents of the table in source order.</p>

  <p>Authors are encouraged to use CSS to achieve these effects.</p>

  <h5>Audio codecs for <code>audio</code> elements</h5>

  <p>User agents may support any audio codecs and container
  formats.</p>

  <p>User agents must support the WAVE container format with audio
  encoded using the 16 bit PCM (LE) codec, at sampling frequencies of
  11.025kHz, 22.050kHz, and 44.100kHz, and for both mono and
  stereo. <a href="#- -refsWAVE">[WAVE]</a></p>

  <!- - similar note in video codecs section - ->
  <p class="note">Implementations are free to implement support for
  audio codecs either natively, or using platform-specific APIs, or
  using plugins: this specification does not specify how codecs are to
  be implemented.</p>

  <h4 id="edits-and-lists"><span class="secno">4.7.5 </span>Edits and lists</h4>

  <p><i>This section is non-normative.</i></p>
  <p>The content models of the <code><a href="the-ol-element.html#the-ol-element">ol</a></code> and <code><a href="the-ul-element.html#the-ul-element">ul</a></code>
  elements do not allow <code><a href="the-ins-element.html#the-ins-element">ins</a></code> and <code><a href="the-del-element.html#the-del-element">del</a></code> elements
  as children. Lists always represent all their items, including items
  that would otherwise have been marked as deleted.</p>

  <p>To indicate that an item is inserted or deleted, an
  <code><a href="the-ins-element.html#the-ins-element">ins</a></code> or <code><a href="the-del-element.html#the-del-element">del</a></code> element can be wrapped around
  the contents of the <code><a href="the-li-element.html#the-li-element">li</a></code> element. To indicate that an
  item has been replaced by another, a single <code><a href="the-li-element.html#the-li-element">li</a></code> element
  can have one or more <code><a href="the-del-element.html#the-del-element">del</a></code> elements followed by one or
  more <code><a href="the-ins-element.html#the-ins-element">ins</a></code> elements.</p>

  <div class="example">

   <p>In the following example, a list that started empty had items
   added and removed from it over time. The bits in the example that
   have been emphasized show the parts that are the "current" state of
   the list. The list item numbers don't take into account the edits,
   though.</p>

&lt;/ol&gt;</pre>

  </div>

  <div class="example">

   <p>In the following example, a list that started with just fruit
   was replaced by a list with just colors.</p>

  <h4 id="edits-and-tables"><span class="secno">4.7.6 </span>Edits and tables</h4>

  <p><i>This section is non-normative.</i></p>
  <p>The elements that form part of the table model have complicated
  content model requirements that do not allow for the
  <code><a href="the-ins-element.html#the-ins-element">ins</a></code> and <code><a href="the-del-element.html#the-del-element">del</a></code> elements, so indicating edits
  to a table can be difficult.</p>

  <p>To indicate that an entire row or an entire column has been added
  or removed, the entire contents of each cell in that row or column
  can be wrapped in <code><a href="the-ins-element.html#the-ins-element">ins</a></code> or <code><a href="the-del-element.html#the-del-element">del</a></code> elements
  (respectively).</p>

  <div class="example">

   <p>Here, a table's row has been added:</p>

   <pre>&lt;table&gt;
 &lt;thead&gt;
  &lt;tr&gt; &lt;th&gt; Game name           &lt;th&gt; Game publisher   &lt;th&gt; Verdict
 &lt;tbody&gt;
  &lt;tr&gt; &lt;td&gt; Diablo 2            &lt;td&gt; Blizzard         &lt;td&gt; 8/10
  &lt;tr&gt; &lt;td&gt; Portal              &lt;td&gt; Valve            &lt;td&gt; 10/10
<strong>  &lt;tr&gt; &lt;td&gt; &lt;ins&gt;Portal 2&lt;/ins&gt; &lt;td&gt; &lt;ins&gt;Valve&lt;/ins&gt; &lt;td&gt; &lt;ins&gt;10/10&lt;/ins&gt;</strong>
&lt;/table&gt;</pre>

   <p>Here, a column has been removed (the time at which it was removed is given also, as is a link to the page explaining why):</p>

   <pre>&lt;table&gt;
 &lt;thead&gt;
  &lt;tr&gt; &lt;th&gt; Game name           &lt;th&gt; Game publisher   &lt;th&gt; <strong>&lt;del cite="/edits/r192" datetime="2011-05-02 14:23Z"&gt;Verdict&lt;/del&gt;</strong>
 &lt;tbody&gt;
  &lt;tr&gt; &lt;td&gt; Diablo 2            &lt;td&gt; Blizzard         &lt;td&gt; <strong>&lt;del cite="/edits/r192" datetime="2011-05-02 14:23Z"&gt;8/10&lt;/del&gt;</strong>
  &lt;tr&gt; &lt;td&gt; Portal              &lt;td&gt; Valve            &lt;td&gt; <strong>&lt;del cite="/edits/r192" datetime="2011-05-02 14:23Z"&gt;10/10&lt;/del&gt;</strong>
  &lt;tr&gt; &lt;td&gt; Portal 2            &lt;td&gt; Valve            &lt;td&gt; <strong>&lt;del cite="/edits/r192" datetime="2011-05-02 14:23Z"&gt;10/10&lt;/del&gt;</strong>
&lt;/table&gt;</pre>

  </div>

  <p>Generally speaking, there is no good way to indicate more
  complicated edits (e.g. that a cell was removed, moving all
  subsequent cells up or to the left).</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-pre-element">pre</a></code> element <a href="rendering.html#represents">represents</a> a block of
  preformatted text, in which structure is represented by typographic
  conventions rather than by elements.</p>

  <p class="note">In <a href="syntax.html#syntax">the HTML syntax</a>, a leading
  newline character immediately following the <code><a href="#the-pre-element">pre</a></code> element
  start tag is stripped.</p>

  <p>Some examples of cases where the <code><a href="#the-pre-element">pre</a></code> element could
  be used:</p>

  <ul><li>Including an e-mail, with paragraphs indicated by blank lines,
   lists indicated by lines prefixed with a bullet, and so on.</li>

   <li>Including fragments of computer code, with structure indicated
   according to the conventions of that language.</li>

   <li>Displaying ASCII art.</li>

  </ul><p class="note">Authors are encouraged to consider how preformatted
  text will be experienced when the formatting is lost, as will be the
  case for users of speech synthesizers, braille displays, and the
  like. For cases like ASCII art, it is likely that an alternative
  presentation, such as a textual description, would be more
  universally accessible to the readers of the document.</p>

  <p>To represent a block of computer code, the <code><a href="#the-pre-element">pre</a></code>
  element can be used with a <code><a href="the-code-element.html#the-code-element">code</a></code> element; to represent a
  block of computer output the <code><a href="#the-pre-element">pre</a></code> element can be used
  with a <code><a href="the-samp-element.html#the-samp-element">samp</a></code> element. Similarly, the <code><a href="the-kbd-element.html#the-kbd-element">kbd</a></code>
  element can be used within a <code><a href="#the-pre-element">pre</a></code> element to indicate
  text that the user is to enter.</p>

  <div class="impl">

  <p>A newline in a <code><a href="#the-pre-element">pre</a></code> element should separate
  paragraphs for the purposes of the Unicode bidirectional algorithm.
  This requirement may be implemented indirectly through the style
  layer. For example, an HTML+CSS user agent could implement these
  requirements by implementing the CSS 'unicode-bidi' property. <a href="references.html#refsBIDI">[BIDI]</a> <a href="references.html#refsCSS">[CSS]</a></p>

  <div class="example">

   <p>In the following snippet, a sample of computer code is
   presented.</p>

   <pre>&lt;p&gt;This is the &lt;code&gt;Panel&lt;/code&gt; constructor:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;function Panel(element, canClose, closeHandler) {
  this.element = element;
  this.canClose = canClose;
  this.closeHandler = function () { if (closeHandler) closeHandler() };
}&lt;/code&gt;&lt;/pre&gt;</pre>

  </div>

  <div class="example">

   <p>In the following snippet, <code><a href="the-samp-element.html#the-samp-element">samp</a></code> and <code><a href="the-kbd-element.html#the-kbd-element">kbd</a></code>
   elements are mixed in the contents of a <code><a href="#the-pre-element">pre</a></code> element to

  <h3 id="dynamic-markup-insertion"><span class="secno">3.4 </span><dfn>Dynamic markup insertion</dfn></h3>

  <p class="note">APIs for dynamically inserting markup into the
  document interact with the parser, and thus their behavior varies
  depending on whether they are used with <a href="infrastructure.html#html-documents">HTML documents</a>
  (and the <a href="parsing.html#html-parser">HTML parser</a>) or XHTML in <a href="infrastructure.html#xml-documents">XML
  documents</a> (and the <a href="the-xhtml-syntax.html#xml-parser">XML parser</a>).</p>



  <h4 id="opening-the-input-stream"><span class="secno">3.4.1 </span>Opening the input stream</h4>

  <p>The <dfn id="dom-document-open" title="dom-document-open"><code>open()</code></dfn>
  method comes in several variants with different numbers of
  arguments.</p>

  <dl class="domintro"><dt><var title="">document</var> = <var title="">document</var> . <code title="dom-document-open"><a href="#dom-document-open">open</a></code>( [ <var title="">type</var> [, <var title="">replace</var> ] ] )</dt>

   <dd>

    <p>Causes the <code><a href="dom.html#document">Document</a></code> to be replaced in-place, as if
    it was a new <code><a href="dom.html#document">Document</a></code> object, but reusing the
    previous object, which is then returned.</p>

    <p>If the <var title="">type</var> argument is omitted or has the
    value "<code><a href="iana.html#text/html">text/html</a></code>", then the resulting
    <code><a href="dom.html#document">Document</a></code> has an HTML parser associated with it, which
    can be given data to parse using <code title="dom-document-write"><a href="#dom-document-write">document.write()</a></code>. Otherwise, all
    content passed to <code title="dom-document-write"><a href="#dom-document-write">document.write()</a></code> will be parsed
    as plain text.</p>

    <p>If the <var title="">replace</var> argument is present and has
    the value "<code title="">replace</code>", the existing entries in
    the session history for the <code><a href="dom.html#document">Document</a></code> object are
    removed.</p>

    <p>The method has no effect if the <code><a href="dom.html#document">Document</a></code> is still
    being parsed.</p>

    <p>Throws an <code><a href="infrastructure.html#invalidstateerror">InvalidStateError</a></code> exception if the
    <code><a href="dom.html#document">Document</a></code> is an <a href="infrastructure.html#xml-documents" title="XML documents">XML
    document</a>.</p>

   </dd>

   <dt><var title="">window</var> = <var title="">document</var> . <code title="dom-document-open"><a href="#dom-document-open">open</a></code>( <var title="">url</var>, <var title="">name</var>, <var title="">features</var> [, <var title="">replace</var> ] )</dt>

   <dd>

    <p>Works like the <code title="dom-open"><a href="browsers.html#dom-open">window.open()</a></code>
    method.</p>

   </dd>

  </dl><div class="impl">

  <p><code><a href="dom.html#document">Document</a></code> objects have an
  <dfn id="ignore-opens-during-unload-counter">ignore-opens-during-unload counter</dfn>, which is used to
  prevent scripts from invoking the <code title="dom-document-open"><a href="#dom-document-open">document.open()</a></code> method (directly or
  indirectly) while the document is <a href="history.html#unload-a-document" title="unload a
  document">being unloaded</a>. Initially, the counter must be set
  to zero.</p> <!-- http://www.hixie.ch/tests/adhoc/dom/level0/document/open/unload/ -->

  <p>When called with two or fewer arguments, the <code title="dom-document-open"><a href="#dom-document-open">document.open()</a></code> method must act as
  follows:</p>

  <ol><li>If the <code><a href="dom.html#document">Document</a></code> object is not flagged as an <a href="infrastructure.html#html-documents" title="HTML documents">HTML document</a>, throw an
   <code><a href="infrastructure.html#invalidstateerror">InvalidStateError</a></code> exception and abort these
   steps.</li>

   <li><p>Let <var title="">type</var> be the value of the first
   argument, if there is one, or "<code><a href="iana.html#text/html">text/html</a></code>"
   otherwise.</p></li>

   <li><p>Let <var title="">replace</var> be true if there is a second
   argument and it is an <a href="infrastructure.html#ascii-case-insensitive">ASCII case-insensitive</a> match for
   the value "replace", and false otherwise.</p></li>

   <li>

    <p>If the <code><a href="dom.html#document">Document</a></code> has an <a href="dom.html#active-parser">active parser</a>
    that isn't a <a href="#script-created-parser">script-created parser</a>, and the
    <a href="parsing.html#insertion-point">insertion point</a> associated with that parser's
    <a href="parsing.html#input-stream">input stream</a> is not undefined (that is, it
    <em>does</em> point to somewhere in the input stream), then the
    method does nothing. Abort these steps and return the
    <code><a href="dom.html#document">Document</a></code> object on which the method was invoked.</p>

    <p class="note">This basically causes <code title="dom-document-open"><a href="#dom-document-open">document.open()</a></code> to be ignored
    when it's called in an inline script found during the parsing of
    data sent over the network, while still letting it have an effect
    when called asynchronously or on a document that is itself being
    spoon-fed using these APIs.</p>

   </li>

   <li>

    <p>Similarly, if the <code><a href="dom.html#document">Document</a></code>'s
    <a href="#ignore-opens-during-unload-counter">ignore-opens-during-unload counter</a> is greater than
    zero, then the method does nothing. Abort these steps and return
    the <code><a href="dom.html#document">Document</a></code> object on which the method was
    invoked.</p>

    <p class="note">This basically causes <code title="dom-document-open"><a href="#dom-document-open">document.open()</a></code> to be ignored
    when it's called from a <code title="event-beforeunload">beforeunload</code> <code title="event-pagehide"><a href="history.html#event-pagehide">pagehide</a></code>, or <code title="event-unload">unload</code> event handler while the
    <code><a href="dom.html#document">Document</a></code> is being unloaded.</p>

   </li>

   <li><p>Release the <a href="webappapis.html#storage-mutex">storage mutex</a>.</p></li>

   <li><p>Set the <code><a href="dom.html#document">Document</a></code>'s <var title="concept-document-salvageable"><a href="history.html#concept-document-salvageable">salvageable</a></var> state to

   abort these steps and return the <code><a href="dom.html#document">Document</a></code> object on

   <li><p>Remove all child nodes of the document, without firing any

   <li><p>Replace the <code><a href="dom.html#document">Document</a></code>'s singleton objects with

    <p>In general, adds the given string(s) to the
    <code><a href="dom.html#document">Document</a></code>'s input stream.</p>

    <p class="warning">This method has very idiosyncratic behavior. In
    some cases, this method can affect the state of the <a href="parsing.html#html-parser">HTML

    does not correspond to the source of the document (e.g. if the
    string written is the string "<code title="">&lt;plaintext&gt;</code>" or "<code title="">&lt;!--</code>"). In other cases, the call can clear the
    current page first, as if <code title="dom-document-open"><a href="#dom-document-open">document.open()</a></code> had been called.
    In yet more cases, the method is simply ignored, or throws an
    exception. To make matters worse, the exact behavior of this
    method can in some cases be dependent on network latency<!--

     Namely, in the following case:

        <script>
         document.write('<link rel=stylesheet href=foo.css><script></script>x');
         // at this point, whether the DOM contains an "x" or not depends on how quickly the foo.css file could be processed
        </script>

    -->, which can lead to failures that are very hard to debug.
    <strong>For all these reasons, use of this method is strongly
    discouraged.</strong></p>

  </div>

  <p>An <dfn id="image-map">image map</dfn> allows geometric areas on an image to be
  associated with <a href="links.html#hyperlink" title="hyperlink">hyperlinks</a>.</p>

  <p>An image, in the form of an <code><a href="the-img-element.html#the-img-element">img</a></code> element or an
  <code><a href="the-object-element.html#the-object-element">object</a></code> element representing an image, may be associated
  with an image map (in the form of a <code><a href="the-map-element.html#the-map-element">map</a></code> element) by
  specifying a <dfn id="attr-hyperlink-usemap" title="attr-hyperlink-usemap"><code>usemap</code></dfn> attribute on
  the <code><a href="the-img-element.html#the-img-element">img</a></code> or <code><a href="the-object-element.html#the-object-element">object</a></code> element. The <code title="attr-hyperlink-usemap"><a href="#attr-hyperlink-usemap">usemap</a></code> attribute, if specified,
  must be a <a href="common-microsyntaxes.html#valid-hash-name-reference">valid hash-name reference</a> to a
  <code><a href="the-map-element.html#the-map-element">map</a></code> element.</p>

  <div class="example">

   <p>Consider an image that looks as follows:</p>

   <p><img alt="A line with four shapes in it, equally spaced: a red hollow box, a green circle, a blue triangle, and a yellow four-pointed star." height="150" src="images/sample-usemap.png" width="600"></p>

   <p>If we wanted just the colored areas to be clickable, we could
   do it as follows:</p>

   <pre>&lt;p&gt;
 Please select a shape:
 &lt;img src="shapes.png" usemap="#shapes"
      alt="Four shapes are available: a red hollow box, a green circle, a blue triangle, and a yellow four-pointed star."&gt;
 &lt;map name="shapes"&gt;
  &lt;area shape=rect coords="50,50,100,100"&gt; &lt;!-- the hole in the red box --&gt;
  &lt;area shape=rect coords="25,25,125,125" href="red.html" alt="Red box."&gt;
  &lt;area shape=circle coords="200,75,50" href="green.html" alt="Green circle."&gt;
  &lt;area shape=poly coords="325,25,262,125,388,125" href="blue.html" alt="Blue triangle."&gt;
  &lt;area shape=poly coords="450,25,435,60,400,75,435,90,450,125,465,90,500,75,465,60"
        href="yellow.html" alt="Yellow star."&gt;
 &lt;/map&gt;
&lt;/p&gt;</pre>

  </div>

  <div class="impl">

  <h5 id="processing-model-0"><span class="secno">4.8.14.2 </span>Processing model</h5>

  <p>If an <code><a href="the-img-element.html#the-img-element">img</a></code> element or an <code><a href="the-object-element.html#the-object-element">object</a></code> element
  representing an image has a <code title="attr-hyperlink-usemap"><a href="#attr-hyperlink-usemap">usemap</a></code> attribute specified,
  user agents must process it as follows:</p>

  <ol><li><p>First, <a href="common-microsyntaxes.html#rules-for-parsing-a-hash-name-reference">rules for parsing a hash-name reference</a>
   to a <code><a href="the-map-element.html#the-map-element">map</a></code> element must be followed. This will return
   either an element (the <var title="">map</var>) or null.</p></li>

   <li><p>If that returned null, then abort these steps. The image is
   not associated with an image map after all.</p></li>

   <li><p>Otherwise, the user agent must collect all the
   <code><a href="the-area-element.html#the-area-element">area</a></code> elements that are descendants of the <var title="">map</var>. Let those be the <var title="">areas</var>.</p></li>

  </ol><p>Having obtained the list of <code><a href="the-area-element.html#the-area-element">area</a></code> elements that form
  the image map (the <var title="">areas</var>), interactive user
  agents must process the list in one of two ways.</p>

  <p>If the user agent intends to show the text that the
  <code><a href="the-img-element.html#the-img-element">img</a></code> element represents, then it must use the following
  steps.</p>

  <p class="note">In user agents that do not support images, or that
  have images disabled, <code><a href="the-object-element.html#the-object-element">object</a></code> elements cannot represent
  images, and thus this section never applies (the <a href="content-models.html#fallback-content">fallback
  content</a> is shown instead). The following steps therefore only
  apply to <code><a href="the-img-element.html#the-img-element">img</a></code> elements.</p>

  <ol><li><p>Remove all the <code><a href="the-area-element.html#the-area-element">area</a></code> elements in <var title="">areas</var> that have no <code title="attr-hyperlink-href"><a href="links.html#attr-hyperlink-href">href</a></code> attribute.</p></li>

   <li><p>Remove all the <code><a href="the-area-element.html#the-area-element">area</a></code> elements in <var title="">areas</var> that have no <code title="attr-area-alt"><a href="the-area-element.html#attr-area-alt">alt</a></code> attribute, or whose <code title="attr-area-alt"><a href="the-area-element.html#attr-area-alt">alt</a></code> attribute's value is the empty
   string, <em>if</em> there is another <code><a href="the-area-element.html#the-area-element">area</a></code> element in
   <var title="">areas</var> with the same value in the <code title="attr-hyperlink-href"><a href="links.html#attr-hyperlink-href">href</a></code> attribute and with a
   non-empty <code title="attr-area-alt"><a href="the-area-element.html#attr-area-alt">alt</a></code> attribute.</p></li>

   <li><p>Each remaining <code><a href="the-area-element.html#the-area-element">area</a></code> element in <var title="">areas</var> represents a <a href="links.html#hyperlink">hyperlink</a>. Those
   hyperlinks should all be made available to the user in a manner
   associated with the text of the <code><a href="the-img-element.html#the-img-element">img</a></code>.</p>

   <p>In this context, user agents may represent <code><a href="the-area-element.html#the-area-element">area</a></code> and
   <code><a href="the-img-element.html#the-img-element">img</a></code> elements with no specified <code title="">alt</code> attributes, or whose <code title="">alt</code>
   attributes are the empty string or some other non-visible text, in
   a user-agent-defined fashion intended to indicate the lack of
   suitable author-provided text.</p></li>

  </ol><p>If the user agent intends to show the image and allow interaction
  with the image to select hyperlinks, then the image must be
  associated with a set of layered shapes, taken from the
  <code><a href="the-area-element.html#the-area-element">area</a></code> elements in <var title="">areas</var>, in reverse
  tree order (so the last specified <code><a href="the-area-element.html#the-area-element">area</a></code> element in the
  <var title="">map</var> is the bottom-most shape, and the first
  element in the <var title="">map</var>, in tree order, is the
  top-most shape).</p>

  <p>Each <code><a href="the-area-element.html#the-area-element">area</a></code> element in <var title="">areas</var> must
  be processed as follows to obtain a shape to layer onto the
  image:</p>

  <ol><li><p>Find the state that the element's <code title="attr-area-shape"><a href="the-area-element.html#attr-area-shape">shape</a></code> attribute represents.</p></li>

   <li><p>Use the <a href="common-microsyntaxes.html#rules-for-parsing-a-list-of-integers">rules for parsing a list of integers</a> to
   parse the element's <code title="attr-area-coords"><a href="the-area-element.html#attr-area-coords">coords</a></code>
   attribute, if it is present, and let the result be the <var title="">coords</var> list. If the attribute is absent, let the
   <var title="">coords</var> list be the empty list.</p></li>

   <li><p>If the number of items in the <var title="">coords</var>
   list is less than the minimum number given for the
   <code><a href="the-area-element.html#the-area-element">area</a></code> element's current state, as per the following
   table, then the shape is empty; abort these steps.</p>
    <table><thead><tr><th>State

    </dl><p>For historical reasons, the coordinates must be interpreted
    relative to the <em>displayed</em> image after any stretching
    caused by the CSS 'width' and 'height' properties (or, for non-CSS
    browsers, the image element's <code title="">width</code> and
    <code title="">height</code> attributes &#8212; CSS browsers map
    those attributes to the aforementioned CSS properties).</p>

    <p class="note">Browser zoom features and transforms applied using
    CSS or SVG do not affect the coordinates.</p>

  </ol><p>Pointing device interaction with an image associated with a set
  of layered shapes per the above algorithm must result in the
  relevant user interaction events being first fired to the top-most
  shape covering the point that the pointing device indicated, if any,
  or to the image element itself, if there is no shape covering that
  point. User agents may also allow individual <code><a href="the-area-element.html#the-area-element">area</a></code>
  elements representing <a href="links.html#hyperlink" title="hyperlink">hyperlinks</a> to
  be selected and activated (e.g. using a keyboard).</p>

  <p class="note">Because a <code><a href="the-map-element.html#the-map-element">map</a></code> element (and its
  <code><a href="the-area-element.html#the-area-element">area</a></code> elements) can be associated with multiple
  <code><a href="the-img-element.html#the-img-element">img</a></code> and <code><a href="the-object-element.html#the-object-element">object</a></code> elements, it is possible
  for an <code><a href="the-area-element.html#the-area-element">area</a></code> element to correspond to multiple focusable
  areas of the document.</p>

  <p>Image maps are <a href="infrastructure.html#live">live</a>; if the DOM is mutated, then the
  user agent must act as if it had rerun the algorithms for image
  maps.</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-br-element">br</a></code> element <a href="rendering.html#represents">represents</a> a line
  break.</p>

  <p class="note">While line breaks are usually represented in visual
  media by physically moving subsequent text to a new line, a style
  sheet or user agent would be equally justified in causing line
  breaks to be rendered in a different manner, for instance as green
  dots, or as extra spacing.</p>

  <p><code><a href="#the-br-element">br</a></code> elements must be used only for line breaks that
  are actually part of the content, as in poems or addresses.</p>

  <div class="example">

  <p>The following example is correct usage of the <code><a href="#the-br-element">br</a></code>
  element:</p>

   <pre>&lt;p&gt;P. Sherman&lt;br&gt;
42 Wallaby Way&lt;br&gt;
Sydney&lt;/p&gt;</pre>

  </div>

  <p><code><a href="#the-br-element">br</a></code> elements must not be used for separating thematic
  groups in a paragraph.</p>

  <div class="example">

   <p>The following examples are non-conforming, as they abuse the
   <code><a href="#the-br-element">br</a></code> element:</p>

   <pre>&lt;p&gt;&lt;a ...&gt;34 comments.&lt;/a&gt;&lt;br&gt;
&lt;a ...&gt;Add a comment.&lt;/a&gt;&lt;/p&gt;</pre>

   <pre>&lt;p&gt;&lt;label&gt;Name: &lt;input name="name"&gt;&lt;/label&gt;&lt;br&gt;
&lt;label&gt;Address: &lt;input name="address"&gt;&lt;/label&gt;&lt;/p&gt;</pre>

   <p>Here are alternatives to the above, which are correct:</p>

   <pre>&lt;p&gt;&lt;a ...&gt;34 comments.&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;a ...&gt;Add a comment.&lt;/a&gt;&lt;/p&gt;</pre>

   <pre>&lt;p&gt;&lt;label&gt;Name: &lt;input name="name"&gt;&lt;/label&gt;&lt;/p&gt;
&lt;p&gt;&lt;label&gt;Address: &lt;input name="address"&gt;&lt;/label&gt;&lt;/p&gt;</pre>

  </div>

  <p>If a <a href="content-models.html#paragraph">paragraph</a> consists of nothing but a single
  <code><a href="#the-br-element">br</a></code> element, it represents a placeholder blank line
  (e.g. as in a template). Such blank lines must not be used for
  presentation purposes.</p>

  <div class="impl">

  <p>Any content inside <code><a href="#the-br-element">br</a></code> elements must not be
  considered part of the surrounding text.</p>

  <p>A <code><a href="#the-br-element">br</a></code> element should separate paragraphs for the
  purposes of the Unicode bidirectional algorithm. This requirement
  may be implemented indirectly through the style layer. For example,
  an HTML+CSS user agent could implement these requirements by
  implementing the CSS 'unicode-bidi' property. <a href="references.html#refsBIDI">[BIDI]</a> <a href="references.html#refsCSS">[CSS]</a></p>

  <p>In XHTML, the XML declaration should be used for inline character
  encoding information, if necessary.</p>

  <div class="example">

   <p>In HTML, to declare that the character encoding is UTF-8, the
   author could include the following markup near the top of the
   document (in the <code><a href="the-head-element.html#the-head-element">head</a></code> element):</p>

   <pre>&lt;meta charset="utf-8"&gt;</pre>

   <p>In XML, the XML declaration would be used instead, at the very

   'white-space' requires adjacent regular spaces to be collapsed
   together.</p>

   <p>In the former case, "<samp>yellow&#9085;</samp>" might wrap to
   the next line ("&#9085;" being used here to represent a
   non-breaking space) even though "<samp>yellow</samp>" alone might
   fit at the end of the line; in the latter case,
   "<samp>&#9085;ball</samp>", if wrapped to the start of the line,
   would have visible indentation from the non-breaking space.</p>

   <p>When 'white-space' is set to 'pre-wrap', however, the editing
   rules will instead simply put two regular spaces between the words,
   and should the two words be split at the end of a line, the spaces
   would be neatly removed from the rendering.</p>

  <p>Each element in this specification has a definition that includes
  the following information:</p>

  <dl><dt><dfn id="element-dfn-categories" title="element-dfn-categories">Categories</dfn></dt>

   <dd><p>A list of <a href="content-models.html#content-categories" title="content categories">categories</a>

   <dd>

    <p>A <em>non-normative</em> description of where the element can

    elements that allow this one as a child, and is provided only as a
    convenience.</p>

    <p class="note">For simplicity, only the most specific

    <a href="content-models.html#flow-content-1">flow content</a> and <a href="content-models.html#phrasing-content-1">phrasing content</a> can be

  <p>User agents should also run the <a href="#printing-steps">printing steps</a>
  whenever the user asks for the opportunity to <a href="rendering.html#obtain-a-physical-form">obtain a
  physical form</a> (e.g. printed copy), or the representation of a
  physical form (e.g. PDF copy), of a document.</p>

  <p>The <dfn id="printing-steps">printing steps</dfn> are as follows:</p>

  <ol><li>

    <p>The user agent may display a message to the user and/or may
    abort these steps.</p>

    <p class="example">For instance, a kiosk browser could silently
    ignore any invocations of the <code title="dom-print"><a href="#dom-print">print()</a></code> method.</p>

    <p class="example">For instance, a browser on a mobile device
    could detect that there are no printers in the vicinity and
    display a message saying so before continuing to offer a "save to
    PDF" option.</p>

   </li>

   <li>

    <p>The user agent must <a href="webappapis.html#fire-a-simple-event">fire a simple event</a> named
    <code title="event-beforeprint">beforeprint</code> at the
    <code><a href="browsers.html#window">Window</a></code> object of the <code><a href="dom.html#document">Document</a></code> that is
      being printed, as well as any <a href="browsers.html#nested-browsing-context" title="nested browsing
    context">nested browsing contexts</a> in it.</p>

    <p class="example">The <code title="event-beforeprint">beforeprint</code> event can be used
    to annotate the printed copy, for instance adding the time at
    which the document was printed.</p>

   </li>

   <li>

    <p>The user agent must release the <a href="webappapis.html#storage-mutex">storage mutex</a>.</p>

   </li>

   <li>

    <p>The user agent should offer the user the opportunity to
    <a href="rendering.html#obtain-a-physical-form">obtain a physical form</a> (or the representation of a
    physical form) of the document. The user agent may wait for the
    user to either accept or decline before returning; if so, the user
    agent must <a href="webappapis.html#pause">pause</a> while the method is waiting. Even if
    the user agent doesn't wait at this point, the user agent must use
    the state of the relevant documents as they are at this point in
    the algorithm if and when it eventually creates the alternate
    form.</p>

   </li>

   <li>

    <p>The user agent must <a href="webappapis.html#fire-a-simple-event">fire a simple event</a> named
    <code title="event-afterprint">afterprint</code> at the
    <code><a href="browsers.html#window">Window</a></code> object of the <code><a href="dom.html#document">Document</a></code> that is
    being printed, as well as any <a href="browsers.html#nested-browsing-context" title="nested browsing
    context">nested browsing contexts</a> in it.</p>

    <p class="example">The <code title="event-afterprint">afterprint</code> event can be used
    to revert annotations added in the earlier event, as well as
    showing post-printing UI. For instance, if a page is walking the
    user through the steps of applying for a home loan, the script
    could automatically advance to the next step after having printed
    a form or other.</p>

  The <dfn id="attr-dim-width" title="attr-dim-width"><code>width</code></dfn> and <dfn id="attr-dim-height" title="attr-dim-height"><code>height</code></dfn> attributes on
  <code><a href="the-img-element.html#the-img-element">img</a></code>, <code><a href="the-iframe-element.html#the-iframe-element">iframe</a></code>, <code><a href="the-embed-element.html#the-embed-element">embed</a></code>,
  <code><a href="the-object-element.html#the-object-element">object</a></code>, <code><a href="the-video-element.html#the-video-element">video</a></code>, and, when their <code title="attr-input-type"><a href="the-input-element.html#attr-input-type">type</a></code> attribute is in the <a href="states-of-the-type-attribute.html#image-button-state-(type=image)" title="attr-input-type-image">Image Button</a> state,
  <code><a href="the-input-element.html#the-input-element">input</a></code> elements may be specified to give the dimensions
  of the visual content of the element (the width and height
  respectively, relative to the nominal direction of the output
  medium), in CSS pixels. The attributes, if specified, must have
  values that are <a href="common-microsyntaxes.html#valid-non-negative-integer" title="valid non-negative integer">valid
  non-negative integers</a>.</p>

  <p>The specified dimensions given may differ from the dimensions
  specified in the resource itself, since the resource may have a
  resolution that differs from the CSS pixel resolution. (On screens,
  CSS pixels have a resolution of 96ppi, but in general the CSS pixel
  resolution depends on the reading distance.) If both attributes are
  specified, then one of the following statements must be true:</p>

  <ul><li><span title=""><var title="">specified width</var> - 0.5 &#8804;
             <var title="">specified height</var> * <var title="">target ratio</var> &#8804;
             <var title="">specified width</var> + 0.5</span></li>

   <li><span title=""><var title="">specified height</var> - 0.5 &#8804;
             <var title="">specified width</var> / <var title="">target ratio</var> &#8804;
             <var title="">specified height</var> + 0.5</span></li>

   <li><span title=""><var title="">specified height</var> = <var title="">specified width</var> = 0</span></li>

  </ul><p>The <var title="">target ratio</var> is the ratio of the
  intrinsic width to the intrinsic height in the resource. The <var title="">specified width</var> and <var title="">specified
  height</var> are the values of the <code title="attr-dim-width"><a href="#attr-dim-width">width</a></code> and <code title="attr-dim-height"><a href="#attr-dim-height">height</a></code> attributes respectively.</p>

  <p>The two attributes must be omitted if the resource in question
  does not have both an intrinsic width and an intrinsic height.</p>

  <p>If the two attributes are both zero, it indicates that the
  element is not intended for the user (e.g. it might be a part of a
  service to count page views).</p>

  <p class="note">The dimension attributes are not intended to be used
  to stretch the image.</p>

  <div class="impl">

  <p><strong>User agent requirements</strong>: User agents are
  expected to use these attributes <a href="rendering.html#dimRendering">as hints
  for the rendering</a>.</p>

  <p>The <dfn id="dom-dim-width" title="dom-dim-width"><code>width</code></dfn> and <dfn id="dom-dim-height" title="dom-dim-height"><code>height</code></dfn> IDL attributes on
  the <code><a href="the-iframe-element.html#the-iframe-element">iframe</a></code>, <code><a href="the-embed-element.html#the-embed-element">embed</a></code>, <code><a href="the-object-element.html#the-object-element">object</a></code>,

  <code><a href="the-object-element.html#the-object-element">object</a></code> the IDL attributes are <code>DOMString</code>;
  for <code><a href="the-video-element.html#the-video-element">video</a></code> the IDL attributes are <code>unsigned
  long</code>.</p>

  <p class="note">The corresponding IDL attributes for <code title="dom-img-height"><a href="the-img-element.html#dom-img-height">img</a></code> and <code title="dom-input-height"><a href="the-input-element.html#dom-input-height">input</a></code> elements are defined in those

  <p>A <a href="forms.html#form-associated-element">form-associated element</a> can have a relationship
  with a <code><a href="the-form-element.html#the-form-element">form</a></code> element, which is called the element's
  <dfn id="form-owner">form owner</dfn>. If a <a href="forms.html#form-associated-element">form-associated element</a> is
  not associated with a <code><a href="the-form-element.html#the-form-element">form</a></code> element, its <a href="#form-owner">form
  owner</a> is said to be null.</p>

  <p>A <a href="forms.html#form-associated-element">form-associated element</a> is, by default, associated
  with its <span class="impl">nearest</span> ancestor
  <code><a href="the-form-element.html#the-form-element">form</a></code> element<span class="impl"> (as described
  below)</span>, but may have a <dfn id="attr-fae-form" title="attr-fae-form"><code>form</code></dfn> attribute specified to
  override this.</p>

  <p class="note">This feature allows authors to work around the lack
  of support for nested <code><a href="the-form-element.html#the-form-element">form</a></code> elements.</p>

  <p>If a <a href="forms.html#form-associated-element">form-associated element</a> has a <code title="attr-fae-form"><a href="#attr-fae-form">form</a></code> attribute specified, then that
  attribute's value must be the <a href="infrastructure.html#concept-id" title="concept-id">ID</a> of a <code><a href="the-form-element.html#the-form-element">form</a></code> element in
  the element's owner <code><a href="dom.html#document">Document</a></code>.</p>

  <div class="impl">

  <p class="note">The rules in this section are complicated by the
  fact that although conforming documents will never contain nested
  <code><a href="the-form-element.html#the-form-element">form</a></code> elements, it is quite possible (e.g. using a
  script that performs DOM manipulation) to generate documents that
  have such nested elements. They are also complicated by rules in the
  HTML parser that, for historical reasons, can result in a
  <a href="forms.html#form-associated-element">form-associated element</a> being associated with a
  <code><a href="the-form-element.html#the-form-element">form</a></code> element that is not its ancestor.</p>

  <p>When a <a href="forms.html#form-associated-element">form-associated element</a> is created, its
  <a href="#form-owner">form owner</a> must be initialized to null (no owner).</p>

  <p>When a <a href="forms.html#form-associated-element">form-associated element</a> is to be <dfn id="concept-form-association" title="concept-form-association">associated</dfn> with a form, its
  <a href="#form-owner">form owner</a> must be set to that form.</p>

  <p>When a <a href="forms.html#form-associated-element">form-associated element</a> or one of its
  ancestors is <a href="infrastructure.html#insert-an-element-into-a-document" title="insert an element into a
  document">inserted into a <code>Document</code></a>, then the
  user agent must <a href="#reset-the-form-owner">reset the form owner</a> of that
  <a href="forms.html#form-associated-element">form-associated element</a>. <span class="note">The
  <a href="parsing.html#html-parser">HTML parser</a> overrides this requirement when inserting
  form controls.</span></p>

  <p>When an element is <a href="infrastructure.html#remove-an-element-from-a-document" title="remove an element from a
  document">removed from a <code>Document</code></a> resulting in a
  <a href="forms.html#form-associated-element">form-associated element</a> and its <a href="#form-owner">form owner</a>
  (if any) no longer being in the same <a href="infrastructure.html#home-subtree">home subtree</a>, then
  the user agent must <a href="#reset-the-form-owner">reset the form owner</a> of that
  <a href="forms.html#form-associated-element">form-associated element</a>.</p>

  <p>When a <a href="forms.html#form-associated-element">form-associated element</a>'s <code title="attr-fae-form"><a href="#attr-fae-form">form</a></code> attribute is set, changed, or
  removed, then the user agent must <a href="#reset-the-form-owner">reset the form owner</a>
  of that element.</p>

  <p>When a <a href="forms.html#form-associated-element">form-associated element</a> has a <code title="attr-fae-form"><a href="#attr-fae-form">form</a></code> attribute and the <a href="infrastructure.html#concept-id" title="concept-id">ID</a> of any of the elements in the
  <code><a href="dom.html#document">Document</a></code> changes, then the user agent must <a href="#reset-the-form-owner">reset
  the form owner</a> of that <a href="forms.html#form-associated-element">form-associated
  element</a>.</p>

  <p>When a <a href="forms.html#form-associated-element">form-associated element</a> has a <code title="attr-fae-form"><a href="#attr-fae-form">form</a></code> attribute and an element with an
  <a href="infrastructure.html#concept-id" title="concept-id">ID</a> is <a href="infrastructure.html#insert-an-element-into-a-document" title="insert an element
  into a document">inserted into</a> or <a href="infrastructure.html#remove-an-element-from-a-document" title="remove an
  element from a document">removed from</a> the
  <code><a href="dom.html#document">Document</a></code>, then the user agent must <a href="#reset-the-form-owner">reset the form
  owner</a> of that <a href="forms.html#form-associated-element">form-associated element</a>.</p>

  <p>When the user agent is to <dfn id="reset-the-form-owner">reset the form owner</dfn> of a
  <a href="forms.html#form-associated-element">form-associated element</a>, it must run the following
  steps:</p>

  <ol><li><p>If the element's <a href="#form-owner">form owner</a> is not null, and
   the element's <code title="attr-fae-form"><a href="#attr-fae-form">form</a></code> content
   attribute is not present, and the element's <a href="#form-owner">form owner</a>
   is its nearest <code><a href="the-form-element.html#the-form-element">form</a></code> element ancestor after the change
   to the ancestor chain, then do nothing, and abort these
   steps.</p></li>

   <li><p>Let the element's <a href="#form-owner">form owner</a> be null.</p></li>

   <li>

    <p>If the element has a <code title="attr-fae-form"><a href="#attr-fae-form">form</a></code>
    content attribute and is itself <a href="infrastructure.html#in-a-document" title="in a Document">in a
    <code>Document</code></a>, then run these substeps:</p>

    <ol><!-- note that this ignores the name="" attribute and is
     unaffected by quirks mode (it's always case sensitive) --><li><p>If the first element <a href="infrastructure.html#in-a-document" title="in a Document">in the
     <code>Document</code></a> to have an <a href="infrastructure.html#concept-id" title="concept-id">ID</a> that is <a href="infrastructure.html#case-sensitive" title="case-sensitive">case-sensitively</a> equal to the
     element's <code title="attr-fae-form"><a href="#attr-fae-form">form</a></code> content
     attribute's value is a <code><a href="the-form-element.html#the-form-element">form</a></code> element, then <a href="#concept-form-association" title="concept-form-association">associate</a> the
     <a href="forms.html#form-associated-element">form-associated element</a> with that <code><a href="the-form-element.html#the-form-element">form</a></code>
     element.</p></li>

     <li><p>Abort the "reset the form owner" steps.</p></li>

    </ol></li>

   <li><p>Otherwise, if the <a href="forms.html#form-associated-element">form-associated element</a> in
   question has an ancestor <code><a href="the-form-element.html#the-form-element">form</a></code> element, then <a href="#concept-form-association" title="concept-form-association">associate</a> the
   <a href="forms.html#form-associated-element">form-associated element</a> with the nearest such ancestor
   <code><a href="the-form-element.html#the-form-element">form</a></code> element.</p></li>

   <li><p>Otherwise, the element is left unassociated.</p></li>

  </ol><div class="example">

   <p>In the following non-conforming snippet:</p>

   <pre class="bad">...
 &lt;form id="a"&gt;
  &lt;div id="b"&gt;&lt;/div&gt;
 &lt;/form&gt;
 &lt;script&gt;
  document.getElementById('b').innerHTML =
     '&lt;table&gt;&lt;tr&gt;&lt;td&gt;&lt;form id="c"&gt;&lt;input id="d"&gt;&lt;/table&gt;' +
     '&lt;input id="e"&gt;';
 &lt;/script&gt;
...</pre>

   <p>The <a href="#form-owner">form owner</a> of "d" would be the inner nested
   form "c", while the <a href="#form-owner">form owner</a> of "e" would be the
   outer form "a".</p>

   <p>This happens as follows: First, the "e" node gets associated
   with "c" in the <a href="parsing.html#html-parser">HTML parser</a>. Then, the <code title="dom-innerHTML"><a href="infrastructure.html#dom-innerhtml">innerHTML</a></code> algorithm moves the nodes
   from the temporary document to the "b" element. At this point, the
   nodes see their ancestor chain change, and thus all the "magic"
   associations done by the parser are reset to normal ancestor
   associations.</p>

   <p>This example is a non-conforming document, though, as it is a
   violation of the content models to nest <code><a href="the-form-element.html#the-form-element">form</a></code>
   elements.</p>

  <hr><!-- Welcome to crazy town. Population: The Web. --><p>Each <code><a href="#the-form-element">form</a></code> element has a mapping of names to elements

  <p>The <a href="infrastructure.html#supported-property-names">supported property names</a> consist of the values

  elements that are descendants of the <code><a href="#the-form-element">form</a></code> element, and
  all the names currently in the <a href="#past-names-map">past names map</a>.</p>

  <p>When a <code><a href="#the-form-element">form</a></code> element is <dfn id="dom-form-nameditem" title="dom-form-namedItem">indexed for named property

   <li><p>Otherwise, <var title="">candidates</var> contains exactly

   in <var title="">candidates</var> in the <code><a href="#the-form-element">form</a></code> element's
   <a href="#past-names-map">past names map</a>, replacing the previous entry with the

  entries must be removed from the map.</p>

  <!--
    This ridiculous setup is intended to do as much of the right thing
    while still supporting code written to work in IE7. IE versions
    prior to IE8 do not update the names on the <form> element
    collection to match new names when elements are renamed, and there
    are enough pages that rename elements and then access them by
    their old name that we have to support this.

    But we still want to expose them using the new names, so as far as
    possible we pretend the legacy names aren't there except if
    there's no other element actually named that way.

    Removing the element did remove the legacy name in IE7:
    http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E...%3Cform%20action%3D%22%2F%22%3E%3Cinput%20name%3Dsubmit%3E%3C%2Fform%3E%0A%3Cscript%3E%0A%20w(document.forms%5B0%5D.submit)%3B%0A%20w(document.forms%5B0%5D.removeChild(document.getElementsByTagName('input')%5B0%5D))%3B%0A%20w(document.forms%5B0%5D.length)%3B%0A%20try%20%7B%20document.forms%5B0%5D.submit()%3B%20%7D%20catch%20(e)%20%20%7B%20w(e.message)%20%7D%0A%3C%2Fscript%3E

    There's no interop on what happens when the name was originally a
    duplicate name, so we don't persist such accesses - at the time
    of writing, Safari returned the first element, Firefox returned
    null (as we do), and IE7 returned the original collection:
    http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E...%3Cform%20action%3D%22%2F%22%3E%3Cinput%20name%3Da%20id%3Dfirst%3E%3Cinput%20name%3Da%20id%3Dsecond%3E%3C%2Fform%3E%0A%3Cscript%3E%0A%20w%28document.forms[0].a%29%3B%0A%20document.getElementsByTagName%28%27input%27%29[0].name%20%3D%20%27b%27%3B%0A%20document.getElementsByTagName%28%27input%27%29[1].name%20%3D%20%27b%27%3B%0A%20w%28document.forms[0].length%29%3B%0A%20w%28document.forms[0].a.id%29%3B%0A%3C%2Fscript%3E

    In addition, the <img> fallback nonsense is similarly here for
    legacy reasons. As is the exclusion of <input type=image>.

  <p class="note">If the <code><a href="#the-li-element">li</a></code> element is the child of a
  <code><a href="the-menu-element.html#the-menu-element">menu</a></code> element and itself has a child that defines a
  <a href="commands.html#concept-command" title="concept-command">command</a>, then the
  <code><a href="#the-li-element">li</a></code> element will match the <code title="selector-enabled"><a href="links.html#selector-enabled">:enabled</a></code> and <code title="selector-disabled"><a href="links.html#selector-disabled">:disabled</a></code> pseudo-classes in the
  same way as the first such child element does.</p>

  <p class="note">While it is conforming to include heading elements
  (e.g. <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code>) inside <code><a href="#the-li-element">li</a></code> elements, it likely
  does not convey the semantics that the author intended. A heading
  starts a new section, so a heading in a list implicitly splits the
  list into spanning multiple sections.</p>

  <p class="note">This specification does not specify how the private
  key generated is to be used. It is expected that after receiving the
  <code><a href="#signedpublickeyandchallenge">SignedPublicKeyAndChallenge</a></code> (SPKAC) structure, the
  server will generate a client certificate and offer it back to the
  user for download; this certificate, once downloaded and stored in
  the key store along with the private key, can then be used to
  authenticate to services that use TLS and certificate
  authentication.</p>

  <!-- how does the UA know which private key is associated with a
  certificate it gets back after the server has taken the public key
  created by <keygen> and turned it into a client cert? -->

  <div class="example">

   <p>To generate a key pair, add the private key to the user's key
   store, and submit the public key to the server, markup such as the
   following can be used:</p>

   <pre>&lt;form action="processkey.cgi" method="post" enctype="multipart/form-data"&gt;
 &lt;p&gt;&lt;keygen name="key"&gt;&lt;/p&gt;
 &lt;p&gt;&lt;input type=submit value="Submit key..."&gt;&lt;/p&gt;
&lt;/form&gt;</pre>

   <p>The server will then receive a form submission with a packaged
   RSA public key as the value of "<code title="">key</code>". This
   can then be used for various purposes, such as generating a client
   certificate, as mentioned above.</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-link-element">link</a></code> element allows authors to link their
  document to other resources.</p>

  <p>The destination of the link(s) is given by the <dfn id="attr-link-href" title="attr-link-href"><code>href</code></dfn> attribute, which must
  be present and must contain a <a href="urls.html#valid-non-empty-url-potentially-surrounded-by-spaces">valid non-empty URL potentially
  surrounded by spaces</a>. <span class="impl">If the <code title="attr-link-href"><a href="#attr-link-href">href</a></code> attribute is absent, then the
  element does not define a link.</span></p>

<!--MD--><!--MD-->
  <p>A <code><a href="#the-link-element">link</a></code> element must have <code title="attr-link-rel"><a href="#attr-link-rel">rel</a></code> attribute.</p>
<!--MD-->

  <p>The types of link indicated (the relationships) are given by the
  value of the <dfn id="attr-link-rel" title="attr-link-rel"><code>rel</code></dfn>
  attribute, which, if present, must have a value that is a <a href="common-microsyntaxes.html#set-of-space-separated-tokens">set
  of space-separated tokens</a>. The <a href="links.html#linkTypes">allowed
  keywords and their meanings</a> are defined in a later
  section. <span class="impl">If the <code title="attr-link-rel"><a href="#attr-link-rel">rel</a></code> attribute is absent, has no
  keywords, or if none of the keywords used are allowed according to
  the definitions in this specification, then the element does not
  create any links.</span></p>

  <p>Two categories of links can be created using the
  <code><a href="#the-link-element">link</a></code> element: <a href="links.html#external-resource-link" title="external resource
  link">Links to external resources</a> and <a href="links.html#hyperlink" title="hyperlink">hyperlinks</a>. The <a href="links.html#linkTypes">link
  types section</a> defines whether a particular link type is an
  external resource or a hyperlink. One <code><a href="#the-link-element">link</a></code> element can
  create multiple links (of which some might be external resource
  links and some might be hyperlinks); exactly which and how many
  links are created depends on the keywords given in the <code title="attr-link-rel"><a href="#attr-link-rel">rel</a></code> attribute. User agents must process
  the links on a per-link basis, not a per-element basis.</p>

  <p class="note">Each link created for a <code><a href="#the-link-element">link</a></code> element is
  handled separately. For instance, if there are two <code><a href="#the-link-element">link</a></code>
  elements with <code title="">rel="stylesheet"</code>, they each
  count as a separate external resource, and each is affected by its
  own attributes independently. Similarly, if a single
  <code><a href="#the-link-element">link</a></code> element has a <code title="attr-link-rel"><a href="#attr-link-rel">rel</a></code> attribute with the value <code title="">next stylesheet</code>, it creates both a
  <a href="links.html#hyperlink">hyperlink</a> (for the <code title="rel-next"><a href="links.html#link-type-next">next</a></code>
  keyword) and an <a href="links.html#external-resource-link">external resource link</a> (for the <code title="rel-stylesheet"><a href="links.html#link-type-stylesheet">stylesheet</a></code> keyword), and they are
  affected by other attributes (such as <code title="attr-link-media"><a href="#attr-link-media">media</a></code> or <code title="attr-link-title"><a href="#attr-link-title">title</a></code>) differently.</p>

  <div class="example">

   <p>For example, the following <code><a href="#the-link-element">link</a></code> element creates two
   hyperlinks (to the same page):</p>

   <pre>&lt;link rel="author license" href="/about"&gt;</pre>

   <p>The two links created by this element are one whose semantic is
   that the target page has information about the current page's
   author, and one whose semantic is that the target page has
   information regarding the license under which the current page is
   provided.</p>

  </div>

  <p>The exact behavior for links to external resources depends on the
  exact relationship, as defined for the relevant link type. Some of
  the attributes control whether or not the external resource is to be
  applied (as defined below).</p>

  <div class="impl">

  <p>For external resources that are represented in the
  DOM (for example, style sheets), the DOM representation must be made
  available even if the resource is not applied. To <dfn id="concept-link-obtain" title="concept-link-obtain">obtain the resource</dfn>, the user
  agent must run the following steps:</p>

  <ol><li><p>If the <code title="attr-link-href"><a href="#attr-link-href">href</a></code> attribute's
   value is the empty string, then abort these steps.</p></li>

   <li><p><a href="urls.html#resolve-a-url" title="resolve a url">Resolve</a> the
   <a href="urls.html#url">URL</a> given by the <code title="attr-link-href"><a href="#attr-link-href">href</a></code> attribute, relative to the
   element.</p></li>

   <li><p>If the previous step fails, then abort these steps.</p></li>

   <li><p><a href="urls.html#fetch">Fetch</a><!--FETCH--> the resulting <a href="urls.html#absolute-url">absolute
   URL</a>.</p></li> <!-- http-origin privacy sensitive -->

  </ol><p>User agents may opt to only try to obtain such resources when
  they are needed, instead of pro-actively <a href="urls.html#fetch" title="fetch">fetching</a> all the external resources that are
  not applied.</p>

  <p>The semantics of the protocol used (e.g. HTTP) must be followed
  when fetching external resources. (For example, redirects will be
  followed and 404 responses will cause the external resource to not
  be applied.)</p>

  <!-- the next few paragraph are similar to text in the <style> section -->
  <p>Once the attempts to obtain the resource and its <a href="infrastructure.html#critical-subresources">critical
  subresources</a> are complete, the user agent must, if the loads
  were successful, <a href="webappapis.html#queue-a-task">queue a task</a> to <a href="webappapis.html#fire-a-simple-event">fire a simple
  event</a> named <code title="event-load">load</code> at the
  <code><a href="#the-link-element">link</a></code> element, or, if the resource or one of its
  <a href="infrastructure.html#critical-subresources">critical subresources</a> failed to completely load for any
  reason (e.g. DNS error, HTTP 404 response, a connection being
  prematurely closed, unsupported Content-Type), <a href="webappapis.html#queue-a-task">queue a
  task</a> to <a href="webappapis.html#fire-a-simple-event">fire a simple event</a> named <code title="event-error">error</code> at the <code><a href="#the-link-element">link</a></code>
  element. Non-network errors in processing the resource or its
  subresources (e.g. CSS parse errors, PNG decoding errors) are not
  failures for the purposes of this paragraph.</p>

  <p>The <a href="webappapis.html#task-source">task source</a> for these <a href="webappapis.html#concept-task" title="concept-task">tasks</a> is the <a href="webappapis.html#dom-manipulation-task-source">DOM manipulation task
  source</a>.</p>

  <p>The element must <a href="the-end.html#delay-the-load-event">delay the load event</a> of the
  element's document until all the attempts to obtain the resource and
  its <a href="infrastructure.html#critical-subresources">critical subresources</a> are complete. (Resources that
  the user agent has not yet attempted to obtain, e.g. because it is
  waiting for the resource to be needed, do not <a href="the-end.html#delay-the-load-event">delay the load
  event</a>.)</p>

  <hr><p id="linkui">Interactive user agents may provide users with a
  means to <a href="links.html#following-hyperlinks-0" title="following hyperlinks">follow the
  hyperlinks</a> created using the <code><a href="#the-link-element">link</a></code> element,
  somewhere within their user interface. The exact interface is not
  defined by this specification, but it could include the following
  information (obtained from the element's attributes, again as
  defined below), in some form or another (possibly simplified), for
  each hyperlink created with each <code><a href="#the-link-element">link</a></code> element in the
  document:</p>

  <ul><!-- the order here is the order that makes most sense for a UI --><li>The relationship between this document and the resource (given

   <li>The address of the resource (given by the <code title="attr-link-href"><a href="#attr-link-href">href</a></code> attribute).</li>

   <li>The language of the resource (given by the <code title="attr-link-hreflang"><a href="#attr-link-hreflang">hreflang</a></code> attribute).</li>

   <li>The optimum media for the resource (given by the <code title="attr-link-media"><a href="#attr-link-media">media</a></code> attribute).</li>

  </ul><p>User agents could also include other information, such as the
  type of the resource (as given by the <code title="attr-link-type"><a href="#attr-link-type">type</a></code> attribute).</p>

  </div>

  <p class="note">Hyperlinks created with the <code><a href="#the-link-element">link</a></code>

  and <code><a href="the-area-element.html#the-area-element">area</a></code> elements, which indicates the type of a link
  whose context is given by the link's location within the

  <p>The <dfn id="attr-link-media" title="attr-link-media"><code>media</code></dfn>

  be a <a href="common-microsyntaxes.html#valid-media-query">valid media query</a>.</p>

  <div class="impl">

  <p>If the link is a <a href="links.html#hyperlink">hyperlink</a> then the <code title="attr-link-media"><a href="#attr-link-media">media</a></code> attribute is purely advisory,
  and describes for which media the document in question was
  designed.</p>

  <p>However, if the link is an <a href="links.html#external-resource-link">external resource link</a>,
  then the <code title="attr-link-media"><a href="#attr-link-media">media</a></code> attribute is
  prescriptive. The user agent must apply the external resource when
  the <code title="attr-link-media"><a href="#attr-link-media">media</a></code> attribute's value
  <a href="common-microsyntaxes.html#matches-the-environment">matches the environment</a> and the other relevant
  conditions apply, and must not apply it otherwise.</p><!-- note
  similar text in <style> section -->

  <p class="note">The external resource might have further
  restrictions defined within that limit its applicability. For
  example, a CSS style sheet might have some <code title="">@media</code> blocks. This specification does not override
  such further restrictions or requirements.</p><!-- note similar text
  in <style> section -->

  </div>

  <p id="default-media">The default, if the <code title="attr-link-media"><a href="#attr-link-media">media</a></code> attribute is omitted, is "<code title="">all</code>", meaning that by default links apply to all
  media.</p>

  <p>The <dfn id="attr-link-hreflang" title="attr-link-hreflang"><code>hreflang</code></dfn>
  attribute on the <code><a href="#the-link-element">link</a></code> element has the same semantics as
  the <a href="links.html#attr-hyperlink-hreflang" title="attr-hyperlink-hreflang"><code>hreflang</code>
  attribute on <code>a</code> and <code>area</code>
  elements</a>.</p>

  <p>The <dfn id="attr-link-type" title="attr-link-type"><code>type</code></dfn> attribute
  gives the <a href="infrastructure.html#mime-type">MIME type</a> of the linked resource. It is
  purely advisory.  The value must be a <a href="infrastructure.html#valid-mime-type">valid MIME
  type</a>.</p>

  <p>For <a href="links.html#external-resource-link" title="external resource link">external resource
  links</a>, the <code title="attr-link-type"><a href="#attr-link-type">type</a></code> attribute
  is used as a hint to user agents so that they can avoid fetching
  resources they do not support. <span class="impl">If the attribute
  is present, then the user agent must assume that the resource is of
  the given type (even if that is not a <a href="infrastructure.html#valid-mime-type">valid MIME type</a>,
  e.g. the empty string). If the attribute is omitted, but the
  external resource link type has a default type defined, then the
  user agent must assume that the resource is of that type. If the UA
  does not support the given <a href="infrastructure.html#mime-type">MIME type</a> for the given link
  relationship, then the UA should not <a href="#concept-link-obtain" title="concept-link-obtain">obtain</a> the resource; if the UA
  does support the given <a href="infrastructure.html#mime-type">MIME type</a> for the given link
  relationship, then the UA should <a href="#concept-link-obtain" title="concept-link-obtain">obtain</a> the resource at the
  appropriate time as specified for the <a href="links.html#external-resource-link">external resource
  link</a>'s particular type. If the attribute is omitted, and the
  external resource link type does not have a default type defined,
  but the user agent would <a href="#concept-link-obtain" title="concept-link-obtain">obtain</a> the resource if the type
  was known and supported, then the user agent should <a href="#concept-link-obtain" title="concept-link-obtain">obtain</a> the resource under the
  assumption that it will be supported.</span></p>

  <div class="impl">

  <p>User agents must not consider the <code title="attr-link-type"><a href="#attr-link-type">type</a></code> attribute authoritative &#8212;
  upon fetching the resource, user agents must not use the <code title="attr-link-type"><a href="#attr-link-type">type</a></code> attribute to determine its actual
  type. Only the actual type (as defined in the next paragraph) is
  used to determine whether to <em>apply</em> the resource, not the
  aforementioned assumed type.</p>

  <p id="concept-link-type-sniffing">If the external resource link
  type defines rules for processing the resource's <a href="urls.html#content-type" title="Content-Type">Content-Type metadata</a>, then those rules
  apply. Otherwise, if the resource is expected to be an image, user
  agents may apply the <a href="urls.html#content-type-sniffing:-image" title="Content-Type sniffing:
  image">image sniffing rules</a>, with the <var title="">official
  type</var> being the type determined from the resource's <a href="urls.html#content-type" title="Content-Type">Content-Type metadata</a>, and use the
  resulting sniffed type of the resource as if it was the actual
  type. Otherwise, if neither of these conditions apply or if the user
  agent opts not to apply the image sniffing rules, then the user
  agent must use the resource's <a href="urls.html#content-type" title="Content-Type">Content-Type metadata</a> to determine the
  type of the resource. If there is no type metadata, but the external
  resource link type has a default type defined, then the user agent
  must assume that the resource is of that type.</p>

  <p class="note">The <code title="rel-stylesheet"><a href="links.html#link-type-stylesheet">stylesheet</a></code>
  link type defines rules for processing the resource's <a href="urls.html#content-type" title="Content-Type">Content-Type metadata</a>.</p>

  <p>Once the user agent has established the type of the resource, the
  user agent must apply the resource if it is of a supported type and
  the other relevant conditions apply, and must ignore the resource
  otherwise.</p>

  <div class="example">

   <p>If a document contains style sheet links labeled as follows:</p>

   <pre>&lt;link rel="stylesheet" href="A" type="text/plain"&gt;
&lt;link rel="stylesheet" href="B" type="text/css"&gt;
&lt;link rel="stylesheet" href="C"&gt;</pre>

   <p>...then a compliant UA that supported only CSS style sheets
   would fetch the B and C files, and skip the A file (since
   <code>text/plain</code> is not the <a href="infrastructure.html#mime-type">MIME type</a> for CSS style
   sheets).</p>

   <p>For files B and C, it would then check the actual types returned
   by the server. For those that are sent as <code>text/css</code>, it
   would apply the styles, but for those labeled as
   <code>text/plain</code>, or any other type, it would not.</p>

   <p>If one of the two files was returned without a
   <a href="urls.html#content-type">Content-Type</a> metadata, or with a syntactically
   incorrect type like <code title="">Content-Type:&#160;"null"</code>, then the default type
   for <code title="rel-stylesheet"><a href="links.html#link-type-stylesheet">stylesheet</a></code> links would kick
   in. Since that default type is <code title="">text/css</code>, the
   style sheet <em>would</em> nonetheless be applied.</p>

  </div>

  </div>

  <p>The <dfn id="attr-link-title" title="attr-link-title"><code>title</code></dfn>
  attribute gives the title of the link. With one exception, it is
  purely advisory. The value is text. The exception is for style sheet
  links, where the <code title="attr-link-title"><a href="#attr-link-title">title</a></code>
  attribute defines <a href="infrastructure.html#alternative-style-sheet-sets">alternative style sheet sets</a>.</p>

  <p class="note">The <code title="attr-link-title"><a href="#attr-link-title">title</a></code>
  attribute on <code><a href="#the-link-element">link</a></code> elements differs from the global
  <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute of most other
  elements in that a link without a title does not inherit the title
  of the parent element: it merely has no title.</p>

  <p>The <code title="attr-link-sizes"><a href="links.html#attr-link-sizes">sizes</a></code> attribute is used
  with the <code title="rel-icon"><a href="links.html#rel-icon">icon</a></code> link type. The attribute
  must not be specified on <code><a href="#the-link-element">link</a></code> elements that do not have
  a <code title="attr-link-rel"><a href="#attr-link-rel">rel</a></code> attribute that specifies
  the <code title="rel-icon"><a href="links.html#rel-icon">icon</a></code> keyword.</p>

  <div class="impl">

  <!--!--><!-- s/header fields/headers/ for consistency with the rest of the spec -->

  <p>HTTP <code title="http-link">Link:</code> header fields, if
  supported, must be assumed to come before any links in the document,
  in the order that they were given in the HTTP message. These header
  fields are to be processed according to the rules given in the
  relevant specifications. <a href="references.html#refsHTTP">[HTTP]</a> <a href="references.html#refsWEBLINK">[WEBLINK]</a></p> <!-- WEBLINK is ref for Link:
  header -->

  <p class="note">Registration of relation types in HTTP Link: header
  fields is distinct from <a href="links.html#linkTypes">HTML link types</a>,
  and thus their semantics can be different from same-named HTML
  types.</p>

  <p>The IDL attributes <dfn id="dom-link-href" title="dom-link-href"><code>href</code></dfn>, <dfn id="dom-link-rel" title="dom-link-rel"><code>rel</code></dfn>, <dfn id="dom-link-media" title="dom-link-media"><code>media</code></dfn>, <dfn id="dom-link-hreflang" title="dom-link-hreflang"><code>hreflang</code></dfn>, <dfn id="dom-link-type" title="dom-link-type"><code>type</code></dfn>, and <dfn id="dom-link-sizes" title="dom-link-sizes"><code>sizes</code></dfn> each must
  <a href="common-dom-interfaces.html#reflect">reflect</a> the respective content attributes of the same
  name.</p>

  <p>The IDL attribute <dfn id="dom-link-rellist" title="dom-link-rellist"><code>relList</code></dfn> <span class="impl">must</span> <a href="common-dom-interfaces.html#reflect" title="reflect">reflect</a> the <code title="attr-link-rel"><a href="#attr-link-rel">rel</a></code> content attribute.</p>

  </div>

  <p>The IDL attribute <dfn id="dom-link-disabled" title="dom-link-disabled"><code>disabled</code></dfn> only applies
  to style sheet links. When the <code><a href="#the-link-element">link</a></code> element defines a
  style sheet link, then the <code title="dom-link-disabled"><a href="#dom-link-disabled">disabled</a></code> attribute behaves as
  defined <a href="styling.html#dom-linkstyle-disabled" title="dom-linkstyle-disabled">for the alternative
  style sheets DOM</a>. For all other <code><a href="#the-link-element">link</a></code> elements it
  always return false and does nothing on setting.</p> <!-- that is
  normatively required in the definition of dom-linkstyle-disabled -->

  <p>The <code><a href="infrastructure.html#linkstyle">LinkStyle</a></code> interface is also implemented by
  this element; the <a href="styling.html#styling">styling processing model</a> defines
  how. <a href="references.html#refsCSSOM">[CSSOM]</a></p>

  <div class="example">

   <p>Here, a set of <code><a href="#the-link-element">link</a></code> elements provide some style
   sheets:</p>

   <pre>&lt;!-- a persistent style sheet --&gt;
&lt;link rel="stylesheet" href="default.css"&gt;

&lt;!-- the preferred alternate style sheet --&gt;

  <p>The <dfn id="attr-param-name" title="attr-param-name"><code>name</code></dfn>

  API that features the ability to update the <a href="infrastructure.html#plugin">plugin</a> when
  the name or value of a <a href="#concept-param-parameter" title="concept-param-parameter">parameter</a> so changes, then
  the user agent must appropriately exercise that ability to notify
  the <a href="infrastructure.html#plugin">plugin</a> of the change.</p>

  <p>The IDL attributes <dfn id="dom-param-name" title="dom-param-name"><code>name</code></dfn> and <dfn id="dom-param-value" title="dom-param-value"><code>value</code></dfn> must both

  </div>

  <div class="example">

   <p>The <code><a href="#the-time-element">time</a></code> element can be used to encode dates, for
   example in microformats. The following shows a hypothetical way of
   encoding an event using a variant on hCalendar that uses the
   <code><a href="#the-time-element">time</a></code> element:</p>

   <pre>&lt;div class="vevent"&gt;
 &lt;a class="url" href="http://www.web2con.com/"&gt;http://www.web2con.com/&lt;/a&gt;
  &lt;span class="summary"&gt;Web 2.0 Conference&lt;/span&gt;:
  &lt;time class="dtstart" datetime="2005-10-05"&gt;October 5&lt;/time&gt; -
  &lt;time class="dtend" datetime="2005-10-07"&gt;7&lt;/time&gt;,
  at the &lt;span class="location"&gt;Argent Hotel, San Francisco, CA&lt;/span&gt;
 &lt;/div&gt;</pre>

  </div>

<!--FORK-->

  <div class="example">

   <p>In the following snippet, the <code><a href="#the-time-element">time</a></code> element is used
   to encode a date in the ISO8601 format, for later processing by a
   script:</p>

   <pre>&lt;p&gt;Our first date was &lt;time datetime="2006-09-23"&gt;a Saturday&lt;/time&gt;.&lt;/p&gt;</pre>

   <p>In this second snippet, the value includes a time:</p>

   <pre>&lt;p&gt;We stopped talking at &lt;time datetime="2006-09-24T05:00-07:00"&gt;5am the next morning&lt;/time&gt;.&lt;/p&gt;</pre>

   <p>A script loaded by the page (and thus privy to the page's
   internal convention of marking up dates and times using the
   <code><a href="#the-time-element">time</a></code> element) could scan through the page and look at
   all the <code><a href="#the-time-element">time</a></code> elements therein to create an index of
   dates and times.</p>

  </div>

  <div class="example">

   <p>For example, this element conveys the string "Tuesday" with
   the additional semantic that the 12th of November 2011 is the
   meaning that corresponds to "Tuesday":</p>

   <pre>Today is &lt;time datetime="2011-11-12"&gt;Tuesday&lt;/time&gt;.</pre>

  </div>

  <div class="example">

   <p>In this example, a specific time in the Pacific Standard Time
   timezone is specified:</p>

   <pre>Your next meeting is at &lt;time datetime="2011-11-12T15:00-08:00"&gt;3pm&lt;/time&gt;.</pre>

  term used as a placeholder in prose.</p>

  <div class="example">
   <p>In the paragraph below, the letter "n" is being used as a
   variable in prose:</p>

cream factory then I expect at &lt;em&gt;least&lt;/em&gt; &lt;var&gt;n&lt;/var&gt;

  <p>For mathematics, in particular for anything beyond the simplest
  of expressions, MathML is more appropriate. However, the
  <code><a href="#the-var-element">var</a></code> element can still be used to refer to specific
  variables that are then mentioned in MathML expressions.</p>

  <div class="example">

   <p>In this example, an equation is shown, with a legend that
   references the variables in the equation. The expression itself is
   marked up with MathML, but the variables are mentioned in the
   figure's legend using <code><a href="#the-var-element">var</a></code>.</p>

   <pre>&lt;figure&gt;
 &lt;math&gt;
  &lt;mi&gt;a&lt;/mi&gt;
  &lt;mo&gt;=&lt;/mo&gt;
  &lt;msqrt&gt;
   &lt;msup&gt;&lt;mi&gt;b&lt;/mi&gt;&lt;mn&gt;2&lt;/mn&gt;&lt;/msup&gt;
   &lt;mi&gt;+&lt;/mi&gt;
   &lt;msup&gt;&lt;mi&gt;c&lt;/mi&gt;&lt;mn&gt;2&lt;/mn&gt;&lt;/msup&gt;
  &lt;/msqrt&gt;
 &lt;/math&gt;

  Using Pythagoras' theorem to solve for the hypotenuse &lt;var&gt;a&lt;/var&gt; of
  a triangle with sides &lt;var&gt;b&lt;/var&gt; and &lt;var&gt;c&lt;/var&gt;
 &lt;/figcaption&gt;
&lt;/figure&gt;</pre>

  </div>

  <div class="example">

   <p>Here, the equation describing mass-energy equivalence is used in
   a sentence, and the <code><a href="#the-var-element">var</a></code> element is used to mark the
   variables and constants in that equation:</p>

   <p>Here is a markup fragment showing a table:</p>

   <pre>&lt;table&gt;
 &lt;thead&gt;
  &lt;tr&gt; &lt;th&gt; ID &lt;th&gt; Measurement &lt;th&gt; Average &lt;th&gt; Maximum

  &lt;tr&gt; &lt;td&gt; 93 &lt;th scope=row&gt; Legs &lt;td&gt; 3.5 &lt;td&gt; 4
  &lt;tr&gt; &lt;td&gt; 10 &lt;th scope=row&gt; Tails &lt;td&gt; 1 &lt;td&gt; 1
 &lt;tbody&gt;
  &lt;tr&gt; &lt;td&gt; &lt;th scope=rowgroup&gt; English speakers &lt;td&gt; &lt;td&gt;
  &lt;tr&gt; &lt;td&gt; 32 &lt;th scope=row&gt; Legs &lt;td&gt; 2.67 &lt;td&gt; 4
  &lt;tr&gt; &lt;td&gt; 35 &lt;th scope=row&gt; Tails &lt;td&gt; 0.33 &lt;td&gt; 1
&lt;/table&gt;</pre>

   <p>This would result in the following table:</p>

   <table><thead><tr><th> ID </th><th> Measurement </th><th> Average </th><th> Maximum
    </th></tr></thead><tbody><tr><td> </td><th scope="rowgroup"> Cats </th><td> </td><td>
     </td></tr><tr><td> 93 </td><th scope="row"> Legs </th><td> 3.5 </td><td> 4

     </td></tr><tr><td> 32 </td><th scope="row"> Legs </th><td> 2.67 </td><td> 4
     </td></tr><tr><td> 35 </td><th scope="row"> Tails </th><td> 0.33 </td><td> 1
   </td></tr></tbody></table><p>The headers in the first row all apply directly down to the rows
   in their column.</p>

   <p>The headers with the explicit <code title="attr-th-scope"><a href="#attr-th-scope">scope</a></code> attributes apply to all the
   cells in their row group other than the cells in the first column.</p>

   <p>The remaining headers apply just to the cells to the right of
   them.</p>

  <h4 id="requirements-relating-to-bidirectional-algorithm-formatting-characters"><span class="secno">3.2.6 </span>Requirements relating to bidirectional-algorithm formatting
  characters</h4>

  <p><a href="content-models.html#text-content">Text content</a> in <a href="infrastructure.html#html-elements">HTML elements</a> with
  child <code><a href="infrastructure.html#text-0">Text</a></code> nodes, and text in attributes of <a href="infrastructure.html#html-elements">HTML
  elements</a> that allow free-form text, may contain characters in
  the range U+202A to U+202E (the bidirectional-algorithm formatting
  characters). However, the use of these characters is restricted so
  that any embedding or overrides generated by these characters do not
  start and end with different parent elements, and so that all such
  embeddings and overrides are explicitly terminated by a U+202C POP
  DIRECTIONAL FORMATTING character. This helps reduce incidences of
  text being reused in a manner that has unforeseen effects on the
  bidirectional algorithm. <a href="references.html#refsBIDI">[BIDI]</a></p>

  <p>The aforementioned restrictions are defined by specifying that
  certain parts of documents form <a href="#bidirectional-algorithm-formatting-character-ranges">bidirectional-algorithm
  formatting character ranges</a>, and then imposing a requirement
  on such ranges.</p>

  <p>The strings resulting from applying the following algorithm to an

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-body-element">body</a></code> element <a href="rendering.html#represents">represents</a> the main
  content of the document.</p>

  <p>In conforming documents, there is only one <code><a href="#the-body-element">body</a></code>
  element. The <code title="dom-document-body"><a href="dom.html#dom-document-body">document.body</a></code>
  IDL attribute provides scripts with easy access to a document's
  <code><a href="#the-body-element">body</a></code> element.</p>

  <div class="impl">

  <p class="note">Some DOM operations (for example, parts of the
  <a href="dnd.html#dnd">drag and drop</a> model) are defined in terms of "<a href="dom.html#the-body-element-0">the
  body element</a>". This refers to a particular element in the
  DOM, as per the definition of the term, and not any arbitrary
  <code><a href="#the-body-element">body</a></code> element.</p>

  </div>

  <p>The <code><a href="#the-body-element">body</a></code> element exposes as <a href="webappapis.html#event-handler-content-attributes">event handler
  content attributes</a> a number of the <a href="webappapis.html#event-handlers">event
  handlers</a> of the <code><a href="browsers.html#window">Window</a></code> object. It also mirrors
  their <a href="webappapis.html#event-handler-idl-attributes">event handler IDL attributes</a>.</p>

  <p>The <code title="handler-window-onblur"><a href="webappapis.html#handler-window-onblur">onblur</a></code>, <code title="handler-window-onerror"><a href="webappapis.html#handler-window-onerror">onerror</a></code>, <code title="handler-window-onfocus"><a href="webappapis.html#handler-window-onfocus">onfocus</a></code>, <code title="handler-window-onload"><a href="webappapis.html#handler-window-onload">onload</a></code>, and <code title="handler-window-onscroll"><a href="webappapis.html#handler-window-onscroll">onscroll</a></code> <a href="webappapis.html#event-handlers">event
  handlers</a> of the <code><a href="browsers.html#window">Window</a></code> object, exposed on the
  <code><a href="#the-body-element">body</a></code> element, shadow the generic <a href="webappapis.html#event-handlers">event
  handlers</a> with the same names normally supported by <a href="infrastructure.html#html-elements">HTML
  elements</a>.</p>

  <p class="example">Thus, for example, a bubbling <code title="event-error">error</code> event dispatched on a child of
  <a href="dom.html#the-body-element-0">the body element</a> of a <code><a href="dom.html#document">Document</a></code> would first
  trigger the <code title="handler-onerror"><a href="webappapis.html#handler-onerror">onerror</a></code> <a href="webappapis.html#event-handler-content-attributes">event
  handler content attributes</a> of that element, then that of the
  root <code><a href="the-html-element.html#the-html-element">html</a></code> element, and only <em>then</em> would it
  trigger the <code title="handler-window-onerror"><a href="webappapis.html#handler-window-onerror">onerror</a></code>
  <a href="webappapis.html#event-handler-content-attributes" title="event handler content attributes">event handler content
  attribute</a> on the <code><a href="#the-body-element">body</a></code> element. This is because
  the event would bubble from the target, to the <code><a href="#the-body-element">body</a></code>, to
  the <code><a href="the-html-element.html#the-html-element">html</a></code>, to the <code><a href="dom.html#document">Document</a></code>, to the
  <code><a href="browsers.html#window">Window</a></code>, and the <a href="webappapis.html#event-handlers" title="event handlers">event
  handler</a> on the <code><a href="#the-body-element">body</a></code> is watching the
  <code><a href="browsers.html#window">Window</a></code> not the <code><a href="#the-body-element">body</a></code>. A regular event
  listener attached to the <code><a href="#the-body-element">body</a></code> using <code title="">addEventListener()</code>, however, would be run when the
  event bubbled through the <code><a href="#the-body-element">body</a></code> and not when it reaches
  the <code><a href="browsers.html#window">Window</a></code> object.</p>

  <div class="example">

   <p>This page updates an indicator to show whether or not the user
   is online:</p>

   <p>In situations where the control's content has one directionality
   but the placeholder needs to have a different directionality,
   Unicode's bidirectional-algorithm formatting characters can be used
   in the attribute value:</p>

   <pre>&lt;input name=t1 type=tel placeholder="<strong>&amp;#x202B;</strong>&#8201;<bdo dir="rtl">&#1585;&#1602;&#1605;&#160;&#1575;&#1604;&#1607;&#1575;&#1578;&#1601;&#160;1</bdo>&#8201;<strong>&amp;#x202E;</strong>"&gt;
&lt;input name=t2 type=tel placeholder="<strong>&amp;#x202B;</strong>&#8201;<bdo dir="rtl">&#1585;&#1602;&#1605;&#160;&#1575;&#1604;&#1607;&#1575;&#1578;&#1601;&#160;2</bdo>&#8201;<strong>&amp;#x202E;</strong>"&gt;</pre>

   <p>For slightly more clarity, here's the same example using numeric character references instead of inline Arabic:</p>

   <pre>&lt;input name=t1 type=tel placeholder="<strong>&amp;#x202B;</strong>&amp;#1585;&amp;#1602;&amp;#1605;&#160;&amp;#1575;&amp;#1604;&amp;#1607;&amp;#1575;&amp;#1578;&amp;#1601;&#160;1<strong>&amp;#x202E;</strong>"&gt;

  contact information for its nearest <code><a href="the-article-element.html#the-article-element">article</a></code> or
  <code><a href="the-body-element.html#the-body-element">body</a></code> element ancestor. If that is <a href="dom.html#the-body-element-0">the body
  element</a>, then the contact information applies to the document
  as a whole.</p>

  <div class="example">
   <p>For example, a page at the W3C Web site related to HTML might
   include the following contact information:</p>
   <pre>&lt;ADDRESS&gt;
 &lt;A href="../People/Raggett/"&gt;Dave Raggett&lt;/A&gt;,
 &lt;A href="../People/Arnaud/"&gt;Arnaud Le Hors&lt;/A&gt;,
 contact persons for the &lt;A href="Activity"&gt;W3C HTML Activity&lt;/A&gt;
&lt;/ADDRESS&gt;</pre>
  </div>

  <p>The <code><a href="#the-address-element">address</a></code> element must not be used to represent
  arbitrary addresses (e.g. postal addresses), unless those addresses
  are in fact the relevant contact information. (The <code><a href="the-p-element.html#the-p-element">p</a></code>
  element is the appropriate element for marking up postal addresses
  in general.)</p>

  <p>The <code><a href="#the-address-element">address</a></code> element must not contain information
  other than contact information.</p>

  <div class="example">
   <p>For example, the following is non-conforming use of the
   <code><a href="#the-address-element">address</a></code> element:</p>
   <pre class="bad">&lt;ADDRESS&gt;Last Modified: 1999/12/24 23:37:50&lt;/ADDRESS&gt;</pre>
  </div>

  <p>Typically, the <code><a href="#the-address-element">address</a></code> element would be included
  along with other information in a <code><a href="the-footer-element.html#the-footer-element">footer</a></code> element.</p>

  <div class="impl">

  <p>The contact information for a node <var title="">node</var> is a

   <dt>If <var title="">node</var> is a <code><a href="the-body-element.html#the-body-element">body</a></code> element</dt>

   <dd>

    <p>The contact information consists of all the
    <code><a href="#the-address-element">address</a></code> elements that have <var title="">node</var>
    as an ancestor and do not have another <code><a href="the-body-element.html#the-body-element">body</a></code> or

   <dt>If <var title="">node</var> has an ancestor element that is an <code><a href="the-article-element.html#the-article-element">article</a></code> element</dt>
   <dt>If <var title="">node</var> has an ancestor element that is a <code><a href="the-body-element.html#the-body-element">body</a></code> element</dt>

   <dd>

    <p>The contact information of <var title="">node</var> is the same

   </dd>

   <dt>Otherwise</dt>

   <dd>

   <dt>Security considerations:</dt>
   <dd>

    <p>Entire novels have been written about the security
    considerations that apply to HTML documents. Many are listed in
    this document, to which the reader is referred for more
    details. Some general concerns bear mentioning here, however:</p>

    <p>HTML is scripted language, and has a large number of APIs (some
    of which are described in this document). Script can expose the
    user to potential risks of information leakage, credential
    leakage, cross-site scripting attacks, cross-site request
    forgeries, and a host of other problems. While the designs in this
    specification are intended to be safe if implemented correctly, a
    full implementation is a massive undertaking and, as with any
    software, user agents are likely to have security bugs.</p>

    <p>Even without scripting, there are specific features in HTML
    which, for historical reasons, are required for broad
    compatibility with legacy content but that expose the user to
    unfortunate security problems. In particular, the <code><a href="the-img-element.html#the-img-element">img</a></code>
    element can be used in conjunction with some other features as a
    way to effect a port scan from the user's location on the
    Internet. This can expose local network topologies that the
    attacker would otherwise not be able to determine.</p>

    <p>HTML relies on a compartmentalization scheme sometimes known as
    the <i>same-origin policy</i>. An <a href="browsers.html#origin-0">origin</a> in most
    cases consists of all the pages served from the same host, on the
    same port, using the same protocol.</p>

    <p>It is critical, therefore, to ensure that any untrusted content
    that forms part of a site be hosted on a different
    <a href="browsers.html#origin-0">origin</a> than any sensitive content on that site.
    Untrusted content can easily spoof any other page on the same
    origin, read data from that origin, cause scripts in that origin
    to execute, submit forms to and from that origin even if they are
    protected from cross-site request forgery attacks by unique
    tokens, and make use of any third-party resources exposed to or
    rights granted to that origin.</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-b-element">b</a></code> element <a href="rendering.html#represents">represents</a> a span of text
  to which attention is being drawn for utilitarian purposes without
  conveying any extra importance and with no implication of an
  alternate voice or mood, such as key words in a document abstract,
  product names in a review, actionable words in interactive
  text-driven software, or an article lede.</p>

  <div class="example">
   <p>The following example shows a use of the <code><a href="#the-b-element">b</a></code> element
   to highlight key words without marking them up as important:</p>
   <pre>&lt;p&gt;The &lt;b&gt;frobonitor&lt;/b&gt; and &lt;b&gt;barbinator&lt;/b&gt; components are fried.&lt;/p&gt;</pre>
  </div>

  <div class="example">
   <p>In the following example, objects in a text adventure are
   highlighted as being special by use of the <code><a href="#the-b-element">b</a></code>
   element.</p>
   <pre>&lt;p&gt;You enter a small room. Your &lt;b&gt;sword&lt;/b&gt; glows
brighter. A &lt;b&gt;rat&lt;/b&gt; scurries past the corner wall.&lt;/p&gt;</pre>
  </div>

  <div class="example">
   <p>Another case where the <code><a href="#the-b-element">b</a></code> element is appropriate is
   in marking up the lede (or lead) sentence or paragraph. The
   following example shows how a <a href="http://news.bbc.co.uk/2/hi/uk_news/scotland/north_east/7101506.stm">BBC
   article about kittens adopting a rabbit as their own</a> could be
   marked up:</p>
   <pre>&lt;article&gt;
 &lt;h2&gt;Kittens 'adopted' by pet rabbit&lt;/h2&gt;
 &lt;p&gt;&lt;b class="lede"&gt;Six abandoned kittens have found an
 unexpected new mother figure &#8212; a pet rabbit.&lt;/b&gt;&lt;/p&gt;
 &lt;p&gt;Veterinary nurse Melanie Humble took the three-week-old
 kittens to her Aberdeen home.&lt;/p&gt;
<i>[...]</i></pre>
  </div>

  <p>As with the <code><a href="the-i-element.html#the-i-element">i</a></code> element, authors can use the <code title="attr-class"><a href="global-attributes.html#classes">class</a></code> attribute on the <code><a href="#the-b-element">b</a></code>
  element to identify why the element is being used, so that if the
  style of a particular use is to be changed at a later date, the
  author doesn't have to go through annotating each use.</p>

  <p>The <code><a href="#the-b-element">b</a></code> element should be used as a last resort when
  no other element is more appropriate. In particular, headings should
  use the <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code> to <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h6</a></code> elements, stress emphasis
  should use the <code><a href="the-em-element.html#the-em-element">em</a></code> element, importance should be denoted
  with the <code><a href="the-strong-element.html#the-strong-element">strong</a></code> element, and text marked or highlighted
  should use the <code><a href="the-mark-element.html#the-mark-element">mark</a></code> element.</p>

  <div class="example">
   <p>The following would be <em>incorrect</em> usage:</p>
   <pre class="bad">&lt;p&gt;&lt;b&gt;WARNING!&lt;/b&gt; Do not frob the barbinator!&lt;/p&gt;</pre>
   <p>In the previous example, the correct element to use would have
   been <code><a href="the-strong-element.html#the-strong-element">strong</a></code>, not <code><a href="#the-b-element">b</a></code>.</p>
  </div>

  <p class="note">Style sheets can be used to format <code><a href="#the-b-element">b</a></code>
  elements, just like any other element can be restyled. Thus, it is
  not the case that content in <code><a href="#the-b-element">b</a></code> elements will
  necessarily be boldened.</p>

  </p><p class="example">For example, it would be confusing to users if an
  American English page claimed that a Cirque De Soleil show was going
  to be showing on 02/03<!-- Feb 3 (year) -->, but their browser,
  configured to use the British English locale, only showed the date
  03/02<!-- 3 Feb (year) --> in the ticket purchase date picker. Using
  the page's locale would at least ensure that the date was presented
  in the same format everywhere. (There's still a risk that the user
  would end up arriving a month late, of course, but there's only so
  much that can be done about such cultural differences...)</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-nav-element">nav</a></code> element <a href="rendering.html#represents">represents</a> a section of
  a page that links to other pages or to parts within the page: a
  section with navigation links.</p>

  <p class="note">Not all groups of links on a page need to be in a
  <code><a href="#the-nav-element">nav</a></code> element &#8212; the element is primarily intended
  for sections that consist of major navigation blocks. In particular,
  it is common for footers to have a short list of links to various
  pages of a site, such as the terms of service, the home page, and a
  copyright page. The <code><a href="the-footer-element.html#the-footer-element">footer</a></code> element alone is sufficient
  for such cases; while a <code><a href="#the-nav-element">nav</a></code> element can be used in such
  cases, it is usually unnecessary.</p>

  <p class="note">User agents (such as screen readers) that are
  targeted at users who can benefit from navigation information being
  omitted in the initial rendering, or who can benefit from navigation
  information being immediately available, can use this element as a
  way to determine what content on the page to initially skip and/or
  provide on request.</p>

  <div class="example">

   <p>In the following example, the page has several places where
   links are present, but only one of those places is considered a
   navigation section.</p>

   <p>A <code><a href="#the-nav-element">nav</a></code> element doesn't have to contain a list, it
   can contain other kinds of content as well. In this navigation
   block, links are provided in prose:</p>

   <pre>&lt;nav&gt;
 &lt;h1&gt;Navigation&lt;/h1&gt;
 &lt;p&gt;You are on my home page. To the north lies &lt;a href="/blog"&gt;my
 blog&lt;/a&gt;, from whence the sounds of battle can be heard. To the east
 you can see a large mountain, upon which many &lt;a
 href="/school"&gt;school papers&lt;/a&gt; are littered. Far up thus mountain
 you can spy a little figure who appears to be me, desperately
 scribbling a &lt;a href="/school/thesis"&gt;thesis&lt;/a&gt;.&lt;/p&gt;
 &lt;p&gt;To the west are several exits. One fun-looking exit is labeled &lt;a
 href="http://games.example.com/"&gt;"games"&lt;/a&gt;. Another more
 boring-looking exit is labeled &lt;a
 href="http://isp.example.net/"&gt;ISP&#8482;&lt;/a&gt;.&lt;/p&gt;
 &lt;p&gt;To the south lies a dark and dank &lt;a href="/about"&gt;contacts
 page&lt;/a&gt;. Cobwebs cover its disused entrance, and at one point you
 see a rat run quickly out of the page.&lt;/p&gt;

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-meter-element">meter</a></code> element <a href="rendering.html#represents">represents</a> a scalar
  measurement within a known range, or a fractional value; for example
  disk usage, the relevance of a query result, or the fraction of a
  voting population to have selected a particular candidate.</p>

  <p>This is also known as a gauge.</p>

  <p class="note">The <code><a href="#the-meter-element">meter</a></code> element should not be used to
  indicate progress (as in a progress bar). For that role, HTML
  provides a separate <code><a href="the-progress-element.html#the-progress-element">progress</a></code> element.</p>

  <p class="note">The <code><a href="#the-meter-element">meter</a></code> element also does not
  represent a scalar value of arbitrary range &#8212; for example, it
  would be wrong to use this to report a weight, or height, unless
  there is a known maximum value.</p>

  <p>There are six attributes that determine the semantics of the
  gauge represented by the element.</p>

  <p>The <dfn id="attr-meter-min" title="attr-meter-min"><code>min</code></dfn> attribute
  specifies the lower bound of the range, and the <dfn id="attr-meter-max" title="attr-meter-max"><code>max</code></dfn> attribute specifies
  the upper bound. The <dfn id="attr-meter-value" title="attr-meter-value"><code>value</code></dfn> attribute
  specifies the value to have the gauge indicate as the "measured"
  value.</p>

  <p>The other three attributes can be used to segment the gauge's
  range into "low", "medium", and "high" parts, and to indicate which
  part of the gauge is the "optimum" part. The <dfn id="attr-meter-low" title="attr-meter-low"><code>low</code></dfn> attribute specifies
  the range that is considered to be the "low" part, and the <dfn id="attr-meter-high" title="attr-meter-high"><code>high</code></dfn> attribute specifies
  the range that is considered to be the "high" part. The <dfn id="attr-meter-optimum" title="attr-meter-optimum"><code>optimum</code></dfn> attribute
  gives the position that is "optimum"; if that is higher than the
  "high" value  then this indicates that the higher the value, the
  better; if it's lower than the "low" mark then it indicates that
  lower values are better, and naturally if it is in between then it
  indicates that neither high nor low values are good.</p>

  <p><span class="impl"><strong>Authoring
  requirements</strong>:</span> The <code title="attr-meter-value"><a href="#attr-meter-value">value</a></code> attribute must be
  specified. The <code title="attr-meter-value"><a href="#attr-meter-value">value</a></code>, <code title="attr-meter-min"><a href="#attr-meter-min">min</a></code>, <code title="attr-meter-low"><a href="#attr-meter-low">low</a></code>, <code title="attr-meter-high"><a href="#attr-meter-high">high</a></code>, <code title="attr-meter-max"><a href="#attr-meter-max">max</a></code>, and <code title="attr-meter-optimum"><a href="#attr-meter-optimum">optimum</a></code> attributes, when present,
  must have values that are <a href="common-microsyntaxes.html#valid-floating-point-number" title="valid floating-point
  number">valid floating-point numbers</a>.</p>

  <p>In addition, the attributes' values are further constrained:</p>

  <p>Let <var title="">value</var> be the <code title="attr-meter-value"><a href="#attr-meter-value">value</a></code> attribute's number.</p>

  <p>If the <code title="attr-meter-min"><a href="#attr-meter-min">min</a></code> attribute
  attribute is specified, then let <var title="">minimum</var> be that
  attribute's value; otherwise, let it be zero.</p>

  <p>If the <code title="attr-meter-max"><a href="#attr-meter-max">max</a></code> attribute
  attribute is specified, then let <var title="">maximum</var> be that
  attribute's value; otherwise, let it be 1.0.</p>

  <p>The following inequalities must hold, as applicable:</p>

  <ul class="brief"><li><var title="">minimum</var> &#8804; <var title="">value</var> &#8804; <var title="">maximum</var></li>
   <li><var title="">minimum</var> &#8804; <code title="attr-meter-low"><a href="#attr-meter-low">low</a></code> &#8804; <var title="">maximum</var> (if <code title="attr-meter-low"><a href="#attr-meter-low">low</a></code> is specified)</li>

  </ul><p class="note">If no minimum or maximum is specified, then the
  range is assumed to be 0..1, and the value thus has to be within
  that range.</p>

  <p>Authors are encouraged to include a textual representation of the
  gauge's state in the element's contents, for users of user agents
  that do not support the <code><a href="#the-meter-element">meter</a></code> element.</p>

  <div class="example">

   <p>The following examples show three gauges that would all be
   three-quarters full:</p>

   <pre>Storage space usage: &lt;meter value=6 max=8&gt;6 blocks used (out of 8 total)&lt;/meter&gt;
Voter turnout: &lt;meter value=0.75&gt;&lt;img alt="75%" src="graph75.png"&gt;&lt;/meter&gt;
Tickets sold: &lt;meter min="0" max="100" value="75"&gt;&lt;/meter&gt;</pre>

   <p>The following example is incorrect use of the element, because
   it doesn't give a range (and since the default maximum is 1, both
   of the gauges would end up looking maxed out):</p>

   <pre class="bad">&lt;p&gt;The grapefruit pie had a radius of &lt;meter value=12&gt;12cm&lt;/meter&gt;
and a height of &lt;meter value=2&gt;2cm&lt;/meter&gt;.&lt;/p&gt; &lt;!-- <strong>BAD!</strong> --&gt;</pre>

   <p>Instead, one would either not include the meter element, or use
   the meter element with a defined range to give the dimensions in
   context compared to other pies:</p>

   <pre>&lt;p&gt;The grapefruit pie had a radius of 12cm and a height of
2cm.&lt;/p&gt;
&lt;dl&gt;
 &lt;dt&gt;Radius: &lt;dd&gt; &lt;meter min=0 max=20 value=12&gt;12cm&lt;/meter&gt;
 &lt;dt&gt;Height: &lt;dd&gt; &lt;meter min=0 max=10 value=2&gt;2cm&lt;/meter&gt;
&lt;/dl&gt;</pre>

  </div>

  <p>There is no explicit way to specify units in the
  <code><a href="#the-meter-element">meter</a></code> element, but the units may be specified in the
  <code title="attr-title"><a href="global-attributes.html#attr-title">title</a></code> attribute in free-form text.</p>

  <div class="example">

   <p>The example above could be extended to mention the units:</p>

   <pre>&lt;dl&gt;
 &lt;dt&gt;Radius: &lt;dd&gt; &lt;meter min=0 max=20 value=12 title="centimeters"&gt;12cm&lt;/meter&gt;
 &lt;dt&gt;Height: &lt;dd&gt; &lt;meter min=0 max=10 value=2 title="centimeters"&gt;2cm&lt;/meter&gt;

  Otherwise, if the optimum point is less than the low boundary, then

  Finally, if the optimum point is higher than the high boundary, then

  is, where changing the order would not materially change the meaning
  of the document.</p>

  of the <code><a href="#the-ul-element">ul</a></code> element.</p>

  <div class="example">

   <p>The following markup shows a list where the order does not
   matter, and where the <code><a href="#the-ul-element">ul</a></code> element is therefore
   appropriate. Compare this list to the equivalent list in the
   <code><a href="the-ol-element.html#the-ol-element">ol</a></code> section to see an example of the same items using
   the <code><a href="the-ol-element.html#the-ol-element">ol</a></code> element.</p>

   <p>Note that changing the order of the list does not change the
   meaning of the document. The items in the snippet above are given
   in alphabetical order, but in the snippet below they are given in
   order of the size of their current account balance in 2007, without

<!--TOPIC:Offline Web Applications-->
  <p>The <dfn id="attr-html-manifest" title="attr-html-manifest"><code>manifest</code></dfn>
  attribute gives the address of the document's <a href="offline.html#application-cache">application
  cache</a> <a href="offline.html#concept-appcache-manifest" title="concept-appcache-manifest">manifest</a>, if there is
  one. If the attribute is present, the attribute's value must be a
  <a href="urls.html#valid-non-empty-url-potentially-surrounded-by-spaces">valid non-empty URL potentially surrounded by
  spaces</a>.</p>

  <p>The <code title="attr-html-manifest"><a href="#attr-html-manifest">manifest</a></code> attribute
  only <a href="offline.html#concept-appcache-init" title="concept-appcache-init">has an effect</a> during
  the early stages of document load. Changing the attribute
  dynamically thus has no effect (and thus, no DOM API is provided for
  this attribute).</p>

  <p class="note">For the purposes of <a href="offline.html#concept-appcache-init" title="concept-appcache-init">application cache selection</a>,
  later <code><a href="the-base-element.html#the-base-element">base</a></code> elements cannot affect the <a href="urls.html#resolve-a-url" title="resolve a url">resolving of relative URLs</a> in <code title="attr-html-manifest"><a href="#attr-html-manifest">manifest</a></code> attributes, as the
  attributes are processed before those elements are seen.</p>

  <p class="note">The <code title="dom-applicationCache"><a href="offline.html#dom-applicationcache">window.applicationCache</a></code> IDL
  attribute provides scripted access to the offline <a href="offline.html#application-cache">application

  <p>Authors may use the ARIA <code title="attr-aria-role">role</code>
  and <code title="attr-aria-*">aria-*</code> attributes on <a href="infrastructure.html#html-elements">HTML
  elements</a>, in accordance with the requirements described in
  the ARIA specifications, except where these conflict with the
  <span>strong native semantics</span>
<!--FORK--><!--bug 11557-->

  <p>User agents are required to implement ARIA semantics on all
  <a href="infrastructure.html#html-elements">HTML elements</a>, as defined in the ARIA specifications.
  The <span>implicit ARIA semantics</span> defined below must be
  recognized by implementations for the purposes of ARIA processing.

  <p class="note">The ARIA attributes defined in the ARIA
  specifications, and the <span>strong native semantics</span> and
  <span>default implicit ARIA semantics</span> defined below, do not
  have any effect on CSS pseudo-class matching, user interface

  <h5 id="aria-role-attribute"><span class="secno">3.2.7.1 </span>ARIA Role Attribute</h5>

  <p>Every HTML element may have an ARIA <code title="attr-aria-role">role</code> attribute specified. This is an
  ARIA Role attribute as defined by <a href="references.html#refsARIA">[ARIA]</a> <a href="http://www.w3.org/TR/wai-aria/roles#role_definitions">Section
  5.4 Definition of Roles</a>.</p>

  <p>The attribute, if specified, must have a value that is a set of
  space-separated tokens representing the various WAI-ARIA roles that
  the element belongs to.</p>

  <div class="impl">

  <p>The WAI-ARIA role that an HTML element has assigned to it is the
  first non-abstract role found in the list of values generated when the
  <code title="attr-aria-role">role</code> attribute is split on
  spaces.</p>

  </div>

  <h5 id="state-and-property-attributes"><span class="secno">3.2.7.2 </span>State and Property Attributes</h5>

  <p>Every HTML element may have ARIA state and property attributes
  specified. These attributes are defined by <a href="references.html#refsARIA">[ARIA]</a> in <a href="http://www.w3.org/TR/wai-aria/states_and_properties#state_prop_def">Section
  6.6, Definitions of States and Properties (all aria-*
  attributes)</a>.</p>

  <p>These attributes, if specified, must have a value that is the ARIA
  value type in the "Value" field of the definition for the state or
  property, mapped to the appropriate HTML value type according to <a href="references.html#refsARIA">[ARIA]</a> <a href="http://www.w3.org/TR/wai-aria/appendices#typemapping">Section
  10.2 Mapping WAI-ARIA Value types to languages</a> using the HTML 5
  mapping.</p>

  <p>ARIA State and Property attributes can be used on any element. They
  are not always meaningful, however, and in such cases user agents
  might not perform any processing aside from including them in the DOM.
  State and property attributes are processed according to the
  requirements of the sections <a href="#sec-strong-native-semantics">Strong Native Semantics</a> and <a href="#sec-implicit-aria-semantics">Implicit ARIA semantics</a>, as
  well as <a href="references.html#refsARIA">[ARIA]</a> and <a href="references.html#refsARIAIMPL">[ARIAIMPL]</a>.</p>

  <p>The following table defines the <span>strong native
  semantics</span> and corresponding <span>default implicit ARIA
  semantics</span> that apply to <a href="infrastructure.html#html-elements">HTML elements</a>. Each
  language feature (element or attribute) in a cell in the first

<!-- EDITORIAL: this paragraph is redundant with WAI-ARIA and doesn't really make any sense anyway; see bug 9437 --><!--FORK-->
  <p>The WAI-ARIA specification neither requires or forbids user
  agents from enhancing native presentation and interaction behaviors
  on the basis of WAI- ARIA markup. Even mainstream user agents might
  choose to expose metadata or navigational features directly or via
  user-installed extensions; for example, exposing required form
  fields or landmark navigation. User agents are encouraged to
  maximize their usefulness to users, including users without
  disabilities.</p>
<!-- EDITORIAL --><!--FORK-->

  <p>Conformance checkers are encouraged to phrase errors such that
  authors are encouraged to use more appropriate elements rather than
  remove accessibility annotations. For example, if an <code><a href="the-a-element.html#the-a-element">a</a></code>
  element is marked as having the <code title="attr-aria-role-button">button</code> role, a conformance
  checker could say "Use a more appropriate element to represent a
  button, for example a <code><a href="the-button-element.html#the-button-element">button</a></code> element or an
  <code><a href="the-input-element.html#the-input-element">input</a></code> element" rather than "The <code title="attr-aria-role-button">button</code> role cannot be used with
  <code><a href="the-a-element.html#the-a-element">a</a></code> elements".</p>

  </div>

  <div class="example">

   <p>These features can be used to make accessibility tools render
   content to their users in more useful ways. For example, ASCII art,
   which is really an image, appears to be text, and in the absence of
   appropriate annotations would end up being rendered by screen
   readers as a very painful reading of lots of punctuation. Using the
   features described in this section, one can instead make the ATs
   skip the ASCII art and just read the caption:</p>

    <p>This is similar to the previous case: each ideographic
    character in the compound word (the base text) has its reading
    given in hiragana or katakana characters (the ruby annotation).
    The difference is that the base text segments form a compound word
    rather than being separate from each other.

    </p><div class="example"> <!-- B as in BASE -->

  </dl><hr><p>Within a <code><a href="#the-ruby-element">ruby</a></code> element that does not have a
  <code><a href="#the-ruby-element">ruby</a></code> element ancestor, content is segmented and
  segments are placed into three categories: base text segments,
  annotation segments, and ignored segments. Ignored segments do not
  form part of the document's semantics (they consist of some
  <a href="content-models.html#inter-element-whitespace">inter-element whitespace</a> and <code><a href="the-rp-element.html#the-rp-element">rp</a></code> elements,
  the latter of which are used for legacy user agents that do not
  support ruby at all). Base text segments can overlap (with a limit
  of two segments overlapping any one position in the DOM, and with
  any segment having an earlier start point than an overlapping
  segment also having an equal or later end point, and any segment
  have a later end point than an overlapping segment also having an
  equal or earlier start point<!-- if anyone can find a better way of
  phrasing this parenthetical, do let me know! -->). Annotation
  segments correspond to <code><a href="the-rt-element.html#the-rt-element">rt</a></code> elements. Each annotation
  segment can be associated with a base text segment, and each base
  text segment can have annotation segments associated with it. (In a
  conforming document, each base text segment is associated with at
  least one annotation segment, and each annotation segment is
  associated with one base text segment.) A <code><a href="#the-ruby-element">ruby</a></code> element
  <a href="rendering.html#represents">represents</a> the union of the segments of base text it
  contains, along with the mapping from those base text segments to
  annotation segments. Segments are described in terms of DOM ranges;
  annotation segment ranges always consist of exactly one element. <a href="references.html#refsDOMCORE">[DOMCORE]</a></p>

 &lt;h1&gt;My Fish&lt;/h1&gt;
 You can play with my fish simulator.
 &lt;object data="fish.sim"&gt;
  &lt;p&gt;To see the fish simulator, use one of the following links:&lt;/p&gt;
  &lt;ul&gt;
   &lt;li&gt;&lt;a href="fish.sim"&gt;Download simulator file&lt;/a&gt;
   &lt;li&gt;&lt;a href="http://sims.example.com/watch?v=LYds5xY4INU"&gt;Use online simulator&lt;/a&gt;
  &lt;/ul&gt;
  &lt;p&gt;Alternatively, upgrade to the Mellblom Browser.&lt;/p&gt;
 &lt;/object&gt;
 I'm quite proud of it.

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-progress-element">progress</a></code> element <a href="rendering.html#represents">represents</a> the
  completion progress of a task. The progress is either indeterminate,
  indicating that progress is being made but that it is not clear how
  much more work remains to be done before the task is complete (e.g.
  because the task is waiting for a remote host to respond), or the
  progress is a number in the range zero to a maximum, giving the
  fraction of work that has so far been completed.</p>

  <p>There are two attributes that determine the current task
  completion represented by the element. The <dfn id="attr-progress-value" title="attr-progress-value"><code>value</code></dfn> attribute
  specifies how much of the task has been completed, and the <dfn id="attr-progress-max" title="attr-progress-max"><code>max</code></dfn> attribute specifies
  how much work the task requires in total. The units are arbitrary
  and not specified.</p>

  <p class="note">To make a determinate progress bar, add a <code title="attr-progress-value"><a href="#attr-progress-value">value</a></code> attribute with the current
  progress (either a number from 0.0 to 1.0, or, if the <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code> attribute is specified, a
  number from 0 to the value of the <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code> attribute). To make an
  indeterminate progress bar, remove the <code title="attr-progress-value"><a href="#attr-progress-value">value</a></code> attribute.</p>

  <p>Authors are encouraged to also include the current value and the
  maximum value inline as text inside the element, so that the
  progress is made available to users of legacy user agents.</p>

  <div class="example">
   <p>Here is a snippet of a Web application that shows the progress
   of some automated task:</p>
   <pre>&lt;section&gt;
 &lt;h2&gt;Task Progress&lt;/h2&gt;
 &lt;p&gt;Progress: &lt;progress id="p" max=100&gt;&lt;span&gt;0&lt;/span&gt;%&lt;/progress&gt;&lt;/p&gt;
 &lt;script&gt;
  var progressBar = document.getElementById('p');
  function updateProgress(newValue) {
    progressBar.value = newValue;
    progressBar.getElementsByTagName('span')[0].textContent = newValue;
  }
 &lt;/script&gt;
&lt;/section&gt;</pre>
   <p>(The <code>updateProgress()</code> method in this example would
   be called by some other code on the page to update the actual
   progress bar as the task progressed.)</p>
  </div>

  <p>The <code title="attr-progress-value"><a href="#attr-progress-value">value</a></code> and <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code> attributes, when present, must
  have values that are <a href="common-microsyntaxes.html#valid-floating-point-number" title="valid floating-point number">valid
  floating-point numbers</a>. The <code title="attr-progress-value"><a href="#attr-progress-value">value</a></code> attribute, if present, must
  have a value equal to or greater than zero, and less than or equal
  to the value of the <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code>
  attribute, if present, or 1.0, otherwise. The <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code> attribute, if present, must
  have a value greater than zero.</p>

  <p class="note">The <code><a href="#the-progress-element">progress</a></code> element is the wrong
  element to use for something that is just a gauge, as opposed to
  task progress. For instance, indicating disk space usage using
  <code><a href="#the-progress-element">progress</a></code> would be inappropriate. Instead, the
  <code><a href="the-meter-element.html#the-meter-element">meter</a></code> element is available for such use cases.</p>

  <div class="impl">

  <p><strong>User agent requirements</strong>: If the <code title="attr-progress-value"><a href="#attr-progress-value">value</a></code> attribute is omitted, then
  the progress bar is an indeterminate progress bar. Otherwise, it is
  a determinate progress bar.</p>

  <p>If the progress bar is a determinate progress bar and the element
  has a <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code> attribute, the user
  agent must parse the <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code>
  attribute's value according to the <a href="common-microsyntaxes.html#rules-for-parsing-floating-point-number-values">rules for parsing
  floating-point number values</a>. If this does not result in an
  error, and if the parsed value is greater than zero, then the <dfn id="concept-progress-maximum" title="concept-progress-maximum">maximum value</dfn> of the progress
  bar is that value. Otherwise, if the element has no <code title="attr-progress-max"><a href="#attr-progress-max">max</a></code> attribute, or if it has one but
  parsing it resulted in an error, or if the parsed value was less
  than or equal to zero, then the <a href="#concept-progress-maximum" title="concept-progress-maximum">maximum value</a> of the
  progress bar is 1.0.</p>

  <p>If the progress bar is a determinate progress bar, user agents
  must parse the <code title="attr-progress-value"><a href="#attr-progress-value">value</a></code>
  attribute's value according to the <a href="common-microsyntaxes.html#rules-for-parsing-floating-point-number-values">rules for parsing
  floating-point number values</a>. If this does not result in an
  error, and if the parsed value is less than the <a href="#concept-progress-maximum" title="concept-progress-maximum">maximum value</a> and greater
  than zero, then the <dfn id="concept-progress-value" title="concept-progress-value">current
  value</dfn> of the progress bar is that parsed value. Otherwise, if
  the parsed value was greater than or equal to the <a href="#concept-progress-maximum" title="concept-progress-maximum">maximum value</a>, then the
  <a href="#concept-progress-value" title="concept-progress-value">current value</a> of the
  progress bar is the <a href="#concept-progress-maximum" title="concept-progress-maximum">maximum
  value</a> of the progress bar. Otherwise, if parsing the <code title="attr-progress-value"><a href="#attr-progress-value">value</a></code> attribute's value resulted
  in an error, or a number less than or equal to zero, then the <a href="#concept-progress-value" title="concept-progress-value">current value</a> of the progress
  bar is zero.</p>

  <p><strong>UA requirements for showing the progress bar</strong>:
  When representing a <code><a href="#the-progress-element">progress</a></code> element to the user, the
  UA should indicate whether it is a determinate or indeterminate
  progress bar, and in the former case, should indicate the relative
  position of the <a href="#concept-progress-value" title="concept-progress-value">current
  value</a> relative to the <a href="#concept-progress-maximum" title="concept-progress-maximum">maximum value</a>.</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-footer-element">footer</a></code> element <a href="rendering.html#represents">represents</a> a footer
  for its nearest ancestor <a href="content-models.html#sectioning-content-0">sectioning content</a> or
  <a href="headings-and-sections.html#sectioning-root">sectioning root</a> element. A footer typically contains
  information about its section such as who wrote it, links to related
  documents, copyright data, and the like.</p>

  <p>When the <code><a href="#the-footer-element">footer</a></code> element contains entire sections,
  they <a href="rendering.html#represents" title="represents">represent</a> appendices, indexes,
  long colophons, verbose license agreements, and other such
  content.</p>

  <p class="note">Contact information for the author or editor of a
  section belongs in an <code><a href="the-address-element.html#the-address-element">address</a></code> element, possibly itself
  inside a <code><a href="#the-footer-element">footer</a></code>. Bylines and other information that
  could be suitable for both a <code><a href="the-header-element.html#the-header-element">header</a></code> or a
  <code><a href="#the-footer-element">footer</a></code> can be placed in either (or neither). The
  primary purpose of these elements is merely to help the author write
  self-explanatory markup that is easy to maintain and style; they are
  not intended to impose specific structures on authors.</p>

  <p>Footers don't necessarily have to appear at the <em>end</em> of a
  section, though they usually do.</p>

  <p>When the nearest ancestor <a href="content-models.html#sectioning-content-0">sectioning content</a> or
  <a href="headings-and-sections.html#sectioning-root">sectioning root</a> element is <a href="dom.html#the-body-element-0">the body
  element</a>, then it applies to the whole page.</p>

  <p class="note">The <code><a href="#the-footer-element">footer</a></code> element is not
  <a href="content-models.html#sectioning-content-0">sectioning content</a>; it doesn't introduce a new
  section.</p>

  <div class="example">

   <p>Here is a page with two footers, one at the top and one at the
   bottom, with the same content:</p>

   <pre>&lt;body&gt;

   <p>Some site designs have what is sometimes referred to as "fat
   footers" &#8212; footers that contain a lot of material, including
   images, links to other articles, links to pages for sending
   feedback, special offers... in some ways, a whole "front page" in
   the footer.</p>

   <p>This fragment shows the bottom of a page on a site with a "fat

  <h3 id="interactions-with-xpath-and-xslt"><span class="secno">3.3 </span>Interactions with XPath and XSLT</h3>

  <p id="xpath-1.0-processors">Implementations of XPath 1.0 that
  operate on <a href="infrastructure.html#html-documents">HTML documents</a> parsed or created in the
  manners described in this specification (e.g. as part of the <code title="">document.evaluate()</code> API) must act as if the
  following edit was applied to the XPath 1.0 specification.</p>

  <p>First, remove this paragraph:</p>

  <blockquote cite="http://www.w3.org/TR/1999/REC-xpath-19991116#node-tests">

   <p>A <a href="http://www.w3.org/TR/REC-xml-names#NT-QName">QName</a> in the
   node test is expanded into an <a href="http://www.w3.org/TR/1999/REC-xpath-19991116#dt-expanded-name">expanded-name</a>
   using the namespace declarations from the expression context.  This
   is the same way expansion is done for element type names in start
   and end-tags except that the default namespace declared with <code title="">xmlns</code> is not used: if the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName">QName</a> does
   not have a prefix, then the namespace URI is null (this is the same
   way attribute names are expanded).  It is an error if the <a href="http://www.w3.org/TR/REC-xml-names#NT-QName">QName</a> has a
   prefix for which there is no namespace declaration in the
   expression context.</p>

  </blockquote>

  <p>Then, insert in its place the following:</p>

  <blockquote cite="http://www.w3.org/Bugs/Public/show_bug.cgi?id=7059#c37">

   <p>A QName in the node test is expanded into an expanded-name using
   the namespace declarations from the expression context. If the
   QName has a prefix, then there must be a<!-- added 2009-10-27 -
   http://www.w3.org/Bugs/Public/show_bug.cgi?id=8062 --> namespace
   declaration for this prefix in the expression context, and the
   corresponding<!-- typo fixed 2009-10-27 -
   http://www.w3.org/Bugs/Public/show_bug.cgi?id=8063 --> namespace
   URI is the one that is associated with this prefix.  It is an error
   if the QName has a prefix for which there is no namespace
   declaration in the expression context. </p>

   <p>If the QName has no prefix and the principal node type of the
   axis is element, then the default element namespace is
   used. Otherwise if the QName has no prefix, the namespace URI is
   null. The default element namespace is a member of the context for
   the XPath expression. The value of the default element namespace
   when executing an XPath expression through the DOM3 XPath API is
   determined in the following way:</p>

   <ol><li>If the context node is from an HTML DOM, the default element
    namespace is "http://www.w3.org/1999/xhtml".</li>

    <li>Otherwise, the default element namespace URI is null.</li>

   </ol><p class="note">This is equivalent to adding the default element
   namespace feature of XPath 2.0 to XPath 1.0, and using the HTML
   namespace as the default element namespace for HTML documents. It
   is motivated by the desire to have implementations be compatible
   with legacy HTML content while still supporting the changes that
   this specification introduces to HTML regarding the namespace used
   for HTML elements, and by the desire to use XPath 1.0 rather than
   XPath 2.0.</p>

  </blockquote>

  <p class="note">This change is a <a href="introduction.html#willful-violation">willful violation</a> of
  the XPath 1.0 specification, motivated by desire to have
  implementations be compatible with legacy content while still
  supporting the changes that this specification introduces to HTML
  regarding which namespace is used for HTML elements. <a href="references.html#refsXPATH10">[XPATH10]</a></p> <!-- note: version matters for
  this ref -->

  <hr><p id="dom-based-xslt-1.0-processors">XSLT 1.0 processors outputting
  to a DOM when the output method is "html" (either explicitly or via
  the defaulting rule in XSLT 1.0) are affected as follows:</p>

  <p>If the transformation program outputs an element in no namespace,
  the processor must, prior to constructing the corresponding DOM
  element node, change the namespace of the element to the <a href="namespaces.html#html-namespace-0">HTML
  namespace</a>, <a href="infrastructure.html#converted-to-ascii-lowercase" title="converted to ASCII
  lowercase">ASCII-lowercase</a> the element's local name, and
  <a href="infrastructure.html#converted-to-ascii-lowercase" title="converted to ASCII lowercase">ASCII-lowercase</a>
  the names of any non-namespaced attributes on the element.</p>

  <p class="note">This requirement is a <a href="introduction.html#willful-violation">willful violation</a>
  of the XSLT 1.0 specification, required because this specification
  changes the namespaces and case-sensitivity rules of HTML in a
  manner that would otherwise be incompatible with DOM-based XSLT
  transformations. (Processors that serialize the output are
  unaffected.) <a href="references.html#refsXSLT10">[XSLT10]</a></p> <!-- note:
  version matters for this ref -->

  <hr><p>This specification does not specify precisely how XSLT processing
  interacts with the <a href="parsing.html#html-parser">HTML parser</a> infrastructure (for
  example, whether an XSLT processor acts as if it puts any elements
  into a <a href="parsing.html#stack-of-open-elements">stack of open elements</a>). However, XSLT
  processors must <a href="the-end.html#stop-parsing">stop parsing</a> if they successfully
  complete, and must set the <a href="dom.html#current-document-readiness">current document readiness</a>
  first to "<code title="">interactive</code>"<!-- this synchronously
  fires an event --> and then to "<code title="">complete</code>"<!--
  this also synchronously fires an event --> if they are aborted.</p>

  <hr><p>This specification does not specify how XSLT interacts with the
  <a href="history.html#navigate" title="navigate">navigation</a> algorithm, how it fits in
  with the <a href="webappapis.html#event-loop">event loop</a>, nor how error pages are to be
  handled (e.g. whether XSLT errors are to replace an incremental XSLT
  output, or are rendered inline, etc).</p>

  <p class="note">There are also additional non-normative comments
  regarding the interaction of XSLT and HTML <a href="the-script-element.html#scriptTagXSLT">in the <code>script</code> element
  section</a>.</p>

  text directionality formatting control for its children. It allows
  authors to override the Unicode bidirectional algorithm by
  explicitly specifying a direction override. <a href="references.html#refsBIDI">[BIDI]</a></p>

  <p>Authors must specify the <code title="attr-dir"><a href="global-attributes.html#the-dir-attribute">dir</a></code>
  attribute on this element, with the value <code>ltr</code> to
  specify a left-to-right override and with the value <code>rtl</code>

  purposes of the bidirectional algorithm, the user agent must act as
  if there was a U+202D LEFT-TO-RIGHT OVERRIDE character at the start
  of the element, and a U+202C POP DIRECTIONAL FORMATTING at the end
  of the element.</p>

  <p>If the element's <code title="attr-dir"><a href="global-attributes.html#the-dir-attribute">dir</a></code> attribute is

  element.</p>

  <p>The requirements on handling the <code><a href="#the-bdo-element">bdo</a></code> element for the
  bidirectional algorithm may be implemented indirectly through the
  style layer. For example, an HTML+CSS user agent could implement
  these requirements by implementing the CSS 'unicode-bidi' property.

  items, where the items have been intentionally ordered, such that
  changing the order would change the meaning of the document.</p>

  <p>The items of the list are the <code><a href="the-li-element.html#the-li-element">li</a></code> element child nodes
  of the <code><a href="#the-ol-element">ol</a></code> element, in <a href="infrastructure.html#tree-order">tree order</a>.</p>

  <p>The <dfn id="attr-ol-reversed" title="attr-ol-reversed"><code>reversed</code></dfn>
  attribute is a <a href="common-microsyntaxes.html#boolean-attribute">boolean attribute</a>. If present, it
  indicates that the list is a descending list (..., 3, 2, 1). If the
  attribute is omitted, the list is an ascending list (1, 2, 3,
  ...).</p>

  <p>The <dfn id="attr-ol-start" title="attr-ol-start"><code>start</code></dfn>
  attribute, if present, must be a <a href="common-microsyntaxes.html#valid-integer">valid integer</a> giving
  the <a href="the-li-element.html#ordinal-value">ordinal value</a> of the first list item.</p>

  <div class="impl">

  <p>If the <code title="attr-ol-start"><a href="#attr-ol-start">start</a></code> attribute is
  present, user agents must <a href="common-microsyntaxes.html#rules-for-parsing-integers" title="rules for parsing
  integers">parse it as an integer</a>, in order to determine the
  attribute's value. The default value, used if the attribute is
  missing or if the value cannot be converted to a number according to
  the referenced algorithm, is 1 if the element has no <code title="attr-ol-reversed"><a href="#attr-ol-reversed">reversed</a></code> attribute, and is the
  number of child <code><a href="the-li-element.html#the-li-element">li</a></code> elements otherwise.</p>

  <p>The first item in the list has the <a href="the-li-element.html#ordinal-value">ordinal value</a>
  given by the <code><a href="#the-ol-element">ol</a></code> element's <code title="attr-ol-start"><a href="#attr-ol-start">start</a></code> attribute, unless that
  <code><a href="the-li-element.html#the-li-element">li</a></code> element has a <code title="attr-li-value"><a href="the-li-element.html#attr-li-value">value</a></code> attribute with a value that can
  be successfully parsed, in which case it has the <a href="the-li-element.html#ordinal-value">ordinal
  value</a> given by that <code title="attr-li-value"><a href="the-li-element.html#attr-li-value">value</a></code>
  attribute.</p>

  <p>Each subsequent item in the list has the <a href="the-li-element.html#ordinal-value">ordinal
  value</a> given by its <code title="attr-li-value"><a href="the-li-element.html#attr-li-value">value</a></code>
  attribute, if it has one, or, if it doesn't, the <a href="the-li-element.html#ordinal-value">ordinal
  value</a> of the previous item, plus one if the <code title="attr-ol-reversed"><a href="#attr-ol-reversed">reversed</a></code> is absent, or minus one if
  it is present.</p>

  </div>

  <p>The <dfn id="attr-ol-type" title="attr-ol-type"><code>type</code></dfn> attribute
  can be used to specify the kind of marker to use in the list, in the
  cases where that matters (e.g. because items are to be referenced by
  their number/letter). The attribute, if specified, must have a value
  that is a <a href="infrastructure.html#case-sensitive">case-sensitive</a> match for one of the
  characters given in the first cell of one of the rows of the
  following table. <span class="impl">The <code title="attr-ol-type"><a href="#attr-ol-type">type</a></code> attribute represents the state
  given in the cell in the second column of the row whose first cell
  matches the attribute's value; if none of the cells match, or if the
  attribute is omitted, then the attribute represents the <a href="#attr-ol-type-state-decimal" title="attr-ol-type-state-decimal">decimal</a> state.</span></p>

  <p>User agents should render the items of the list in a manner
  consistent with the state of the <code title="attr-ol-type"><a href="#attr-ol-type">type</a></code> attribute of the <code><a href="#the-ol-element">ol</a></code>
  element. Numbers less than or equal to zero should always use the
  decimal system regardless of the <code title="attr-ol-type"><a href="#attr-ol-type">type</a></code> attribute.</p>

  <p class="note">For CSS user agents, a mapping for this attribute to
  the 'list-style-type' CSS property is given <a href="rendering.html#decohints">in
  the rendering section</a> (the mapping is straightforward: the
  states above have the same names as their corresponding CSS
  values).</p>

   <p>The following markup shows a list where the order matters, and
   where the <code><a href="#the-ol-element">ol</a></code> element is therefore appropriate. Compare
   this list to the equivalent list in the <code><a href="the-ul-element.html#the-ul-element">ul</a></code> section to

   <p>Note how changing the order of the list changes the meaning of
   the document. In the following example, changing the relative order
   of the first two items has changed the birthplace of the

  hyperlink with some text and a corresponding area on an <a href="image-maps.html#image-map">image
  map</a>, or a dead area on an image map.</p>

  <p>If the <code><a href="#the-area-element">area</a></code> element has an <code title="attr-hyperlink-href"><a href="links.html#attr-hyperlink-href">href</a></code> attribute, then the
  <code><a href="#the-area-element">area</a></code> element represents a <a href="links.html#hyperlink">hyperlink</a>. In
  this case, the <dfn id="attr-area-alt" title="attr-area-alt"><code>alt</code></dfn>
  attribute must be present. It specifies the text of the
  hyperlink. Its value must be text that, when presented with the
  texts specified for the other hyperlinks of the <a href="image-maps.html#image-map">image
  map</a>, and with the alternative text of the image, but without
  the image itself, provides the user with the same kind of choice as
  the hyperlink would when used without its text but with its shape
  applied to the image. The <code title="attr-area-alt"><a href="#attr-area-alt">alt</a></code>
  attribute may be left blank if there is another <code><a href="#the-area-element">area</a></code>
  element in the same <a href="image-maps.html#image-map">image map</a> that points to the same
  resource and has a non-blank <code title="attr-area-alt"><a href="#attr-area-alt">alt</a></code>
  attribute.</p>

  <p>If the <code><a href="#the-area-element">area</a></code> element has no <code title="attr-hyperlink-href"><a href="links.html#attr-hyperlink-href">href</a></code> attribute, then the area
  represented by the element cannot be selected, and the <code title="attr-area-alt"><a href="#attr-area-alt">alt</a></code> attribute must be omitted.</p>

  <p>In both cases, the <code title="attr-area-shape"><a href="#attr-area-shape">shape</a></code> and
  <code title="attr-area-coords"><a href="#attr-area-coords">coords</a></code> attributes specify the

  <p>In the <dfn id="attr-area-shape-circle" title="attr-area-shape-circle">circle state</dfn>,
  <code><a href="#the-area-element">area</a></code> elements must have a <code title="attr-area-coords"><a href="#attr-area-coords">coords</a></code> attribute present, with three
  integers, the last of which must be non-negative. The first integer
  must be the distance in CSS pixels from the left edge of the image
  to the center of the circle, the second integer must be the distance
  in CSS pixels from the top edge of the image to the center of the
  circle, and the third integer must be the radius of the circle,
  again in CSS pixels.</p>

  <p>In the <dfn id="attr-area-shape-default" title="attr-area-shape-default">default state</dfn>
  state, <code><a href="#the-area-element">area</a></code> elements must not have a <code title="attr-area-coords"><a href="#attr-area-coords">coords</a></code> attribute. (The area is the
  whole image.)</p>

  <p>In the <dfn id="attr-area-shape-poly" title="attr-area-shape-poly">polygon state</dfn>,
  <code><a href="#the-area-element">area</a></code> elements must have a <code title="attr-area-coords"><a href="#attr-area-coords">coords</a></code> attribute with at least six
  integers, and the number of integers must be even. Each pair of
  integers must represent a coordinate given as the distances from the
  left and the top of the image in CSS pixels respectively, and all
  the coordinates together must represent the points of the polygon,
  in order.</p>

  <p>In the <dfn id="attr-area-shape-rect" title="attr-area-shape-rect">rectangle state</dfn>,
  <code><a href="#the-area-element">area</a></code> elements must have a <code title="attr-area-coords"><a href="#attr-area-coords">coords</a></code> attribute with exactly four
  integers, the first of which must be less than the third, and the
  second of which must be less than the fourth. The four points must
  represent, respectively, the distance from the left edge of the
  image to the left side of the rectangle, the distance from the
  top edge to the top side, the distance from the left edge to the
  right side, and the distance from the top edge to the bottom side,
  all in CSS pixels.</p>

  </dl><!--TOPIC:HTML--><!-- v2: attribute that means "highlight this on the scrollbar" --><p>The <code><a href="#the-mark-element">mark</a></code> element <a href="rendering.html#represents">represents</a> a run of
  text in one document marked or highlighted for reference purposes,
  due to its relevance in another context. When used in a quotation or
  other block of text referred to from the prose, it indicates a
  highlight that was not originally present but which has been added
  to bring the reader's attention to a part of the text that might not
  have been considered important by the original author when the block
  was originally written, but which is now under previously unexpected
  scrutiny. When used in the main prose of a document, it indicates a
  part of the document that has been highlighted due to its likely
  relevance to the user's current activity.</p>

  <div class="example">
   <p>This example shows how the <code><a href="#the-mark-element">mark</a></code> element can be used
   to bring attention to a particular part of a quotation:</p>
   <pre>&lt;p lang="en-US"&gt;Consider the following quote:&lt;/p&gt;
&lt;blockquote lang="en-GB"&gt;
 &lt;p&gt;Look around and you will find, no-one's really
 &lt;mark&gt;colour&lt;/mark&gt; blind.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p lang="en-US"&gt;As we can tell from the &lt;em&gt;spelling&lt;/em&gt; of the word,
the person writing this quote is clearly not American.&lt;/p&gt;</pre>
   <p>(If the goal was to mark the element as misspelt, however, the
   <code><a href="the-u-element.html#the-u-element">u</a></code> element, possibly with a class, would be more
   appropriate.)</p>
  </div>

  <div class="example">

   <p>Another example of the <code><a href="#the-mark-element">mark</a></code> element is highlighting
   parts of a document that are matching some search string. If
   someone looked at a document, and the server knew that the user was
   searching for the word "kitten", then the server might return the
   document with one paragraph modified as follows:</p>

   <pre>&lt;p&gt;I also have some &lt;mark&gt;kitten&lt;/mark&gt;s who are visiting me
these days. They're really cute. I think they like my garden! Maybe I
should adopt a &lt;mark&gt;kitten&lt;/mark&gt;.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>In the following snippet, a paragraph of text refers to a
   specific part of a code fragment.</p>

   <pre>&lt;p&gt;The highlighted part below is where the error lies:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;var i: Integer;
begin
   i := &lt;mark&gt;1.1&lt;/mark&gt;;
end.&lt;/code&gt;&lt;/pre&gt;</pre>

   <p>This is separate from <em>syntax highlighting</em>, for which
   <code><a href="the-span-element.html#the-span-element">span</a></code> is more appropriate. Combining both, one would
   get:</p>

   <pre>&lt;p&gt;The highlighted part below is where the error lies:&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;&lt;span class=keyword&gt;var&lt;/span&gt; &lt;span class=ident&gt;i&lt;/span&gt;: &lt;span class=type&gt;Integer&lt;/span&gt;;
&lt;span class=keyword&gt;begin&lt;/span&gt;
   &lt;span class=ident&gt;i&lt;/span&gt; := &lt;span class=literal&gt;&lt;mark&gt;1.1&lt;/mark&gt;&lt;/span&gt;;
&lt;span class=keyword&gt;end&lt;/span&gt;.&lt;/code&gt;&lt;/pre&gt;</pre>

  </div>

  <div class="example">

   <p>This is another example showing the use of <code><a href="#the-mark-element">mark</a></code> to
   highlight a part of quoted text that was originally not
   emphasized. In this example, common typographic conventions have
   led the author to explicitly style <code><a href="#the-mark-element">mark</a></code> elements in
   quotes to render in italics.</p>

   <pre>&lt;article&gt;
 &lt;style scoped&gt;
  blockquote mark, q mark {
    font: inherit; font-style: italic;
    text-decoration: none;
    background: transparent; color: inherit;
  }
  .bubble em {
    font: inherit; font-size: larger;
    text-decoration: underline;
  }
 &lt;/style&gt;
 &lt;h1&gt;She knew&lt;/h1&gt;
 &lt;p&gt;Did you notice the subtle joke in the joke on panel 4?&lt;/p&gt;
 &lt;blockquote&gt;
  &lt;p class="bubble"&gt;I didn't &lt;em&gt;want&lt;/em&gt; to believe. &lt;mark&gt;Of course
  on some level I realized it was a known-plaintext attack.&lt;/mark&gt; But I
  couldn't admit it until I saw for myself.&lt;/p&gt;
 &lt;/blockquote&gt;
 &lt;p&gt;(Emphasis mine.) I thought that was great. It's so pedantic, yet it
 explains everything neatly.&lt;/p&gt;
&lt;/article&gt;</pre>

   <p>Note, incidentally, the distinction between the <code><a href="the-em-element.html#the-em-element">em</a></code>
   element in this example, which is part of the original text being
   quoted, and the <code><a href="#the-mark-element">mark</a></code> element, which is highlighting a
   part for comment.</p>

  </div>

  <div class="example">

   <p>The following example shows the difference between denoting the
   <em>importance</em> of a span of text (<code><a href="the-strong-element.html#the-strong-element">strong</a></code>) as
   opposed to denoting the <em>relevance</em> of a span of text
   (<code><a href="#the-mark-element">mark</a></code>). It is an extract from a textbook, where the
   extract has had the parts relevant to the exam highlighted. The
   safety warnings, important though they may be, are apparently not
   relevant to the exam.</p>

   <pre>&lt;h3&gt;Wormhole Physics Introduction&lt;/h3&gt;

&lt;p&gt;&lt;mark&gt;A wormhole in normal conditions can be held open for a
maximum of just under 39 minutes.&lt;/mark&gt; Conditions that can increase
the time include a powerful energy source coupled to one or both of
the gates connecting the wormhole, and a large gravity well (such as a
black hole).&lt;/p&gt;

&lt;p&gt;&lt;mark&gt;Momentum is preserved across the wormhole. Electromagnetic
radiation can travel in both directions through a wormhole,
but matter cannot.&lt;/mark&gt;&lt;/p&gt;

&lt;p&gt;When a wormhole is created, a vortex normally forms.
&lt;strong&gt;Warning: The vortex caused by the wormhole opening will
annihilate anything in its path.&lt;/strong&gt; Vortexes can be avoided when
using sufficiently advanced dialing technology.&lt;/p&gt;

&lt;p&gt;&lt;mark&gt;An obstruction in a gate will prevent it from accepting a
wormhole connection.&lt;/mark&gt;&lt;/p&gt;</pre>

 v2  * make the spec consistent about whether the word "algorithm" is part of
       an algorithm's name or not ("</dfn> algorithm", "</span> algorithm")
 v2  * make the spec more consistent about its use of "hexadecimal"
       and "base-sixteen", the order that 0-9 A-Z a-z is mentioned,
       and the detail to which the spec explains how to interpret a
       string as a hexadecimal number.
 v2  * become more consistent about what markup we use to mark up
       productions (nothing? <i>? <code>?)
 v2  * use <code>Document</code> consistently instead of 'document'.
 v2  * be clearer about arrays/lists/collections being zero-based
       despite using the term "/index/th".
 v2  * use the sample widgets:

  <p class="note">A <code><a href="#the-header-element">header</a></code> element is intended to usually
  contain the section's heading (an
  <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code>&#8211;<code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h6</a></code> element or an
  <code><a href="the-hgroup-element.html#the-hgroup-element">hgroup</a></code> element), but this is not required. The
  <code><a href="#the-header-element">header</a></code> element can also be used to wrap a section's
  table of contents, a search form, or any relevant logos.</p>

  <div class="example">

  <p>Here are some sample headers. This first one is for a game:</p>

  <h3 id="elements"><span class="secno">3.2 </span>Elements</h3>

  <h4 id="semantics-0"><span class="secno">3.2.1 </span>Semantics</h4>

  <p>Elements, attributes, and attribute values in HTML are defined
  (by this specification) to have certain meanings (semantics). For
  example, the <code><a href="the-ol-element.html#the-ol-element">ol</a></code> element represents an ordered list, and
  the <code title="attr-lang"><a href="global-attributes.html#attr-lang">lang</a></code> attribute represents the
  language of the content.</p>

  <p>These definitions allow HTML processors, such as Web browsers or
  search engines, to present and use documents and applications in a
  wide variety of contexts that the author might not have
  considered.</p>

  <div class="example">

   <p>As a simple example, consider a Web page written by an author
   who only considered desktop computer Web browsers. Because HTML
   conveys <em>meaning</em>, rather than presentation, the same page
   can also be used by a small browser on a mobile phone, without any
   change to the page. Instead of headings being in large letters as
   on the desktop, for example, the browser on the mobile phone might
   use the same size text for the whole the page, but with the
   headings in bold.</p>

   <p>But it goes further than just differences in screen size: the
   same page could equally be used by a blind user using a browser
   based around speech synthesis, which instead of displaying the page
   on a screen, reads the page to the user, e.g. using headphones.
   Instead of large text for the headings, the speech browser might
   use a different volume or a slower voice.</p>

   <p>That's not all, either. Since the browsers know which parts of
   the page are the headings, they can create a document outline that
   the user can use to quickly navigate around the document, using
   keys for "jump to next heading" or "jump to previous heading". Such
   features are especially common with speech browsers, where users
   would otherwise find quickly navigating a page quite difficult.</p>

   <p>Even beyond browsers, software can make use of this information.
   Search engines can use the headings to more effectively index a
   page, or to provide quick links to subsections of the page from
   their results. Tools can use the headings to create a table of
   contents (that is in fact how this very specification's table of
   contents is generated).</p>

   <p>This example has focused on headings, but the same principle
   applies to all of the semantics in HTML.</p>

  </div>

  <p>Authors must not use elements, attributes, or attribute values
  for purposes other than their appropriate intended semantic purpose,
  as doing so prevents software from correctly processing the
  page.</p>

  <div class="example">

   <p>For example, the following document is non-conforming, despite
   being syntactically correct:</p>

   <pre class="bad">&lt;!DOCTYPE HTML&gt;
&lt;html lang="en-GB"&gt;
 &lt;head&gt; &lt;title&gt; Demonstration &lt;/title&gt; &lt;/head&gt;
 &lt;body&gt;
  &lt;table&gt;
   &lt;tr&gt; &lt;td&gt; My favourite animal is the cat. &lt;/td&gt; &lt;/tr&gt;
   &lt;tr&gt;
    &lt;td&gt;
     &#8212;&lt;a href="http://example.org/~ernest/"&gt;&lt;cite&gt;Ernest&lt;/cite&gt;&lt;/a&gt;,
     in an essay from 1992
    &lt;/td&gt;
   &lt;/tr&gt;
  &lt;/table&gt;
 &lt;/body&gt;
&lt;/html&gt;</pre>

   <p>...because the data placed in the cells is clearly not tabular
   data (and the <code><a href="the-cite-element.html#the-cite-element">cite</a></code> element mis-used). This would make
   software that relies on these semantics fail: for example, a speech
   browser that allowed a blind user to navigate tables in the
   document would report the quote above as a table, confusing the
   user; similarly, a tool that extracted titles of works from pages
   would extract "Ernest" as the title of a work, even though it's
   actually a person's name, not a title.</p>

   <p>A corrected version of this document might be:</p>

   <pre>&lt;!DOCTYPE HTML&gt;
&lt;html lang="en-GB"&gt;
 &lt;head&gt; &lt;title&gt; Demonstration &lt;/title&gt; &lt;/head&gt;
 &lt;body&gt;
  &lt;blockquote&gt;
   &lt;p&gt; My favourite animal is the cat. &lt;/p&gt;
  &lt;/blockquote&gt;
  &lt;p&gt;
   &#8212;&lt;a href="http://example.org/~ernest/"&gt;Ernest&lt;/a&gt;,
   in an essay from 1992
  &lt;/p&gt;
 &lt;/body&gt;
&lt;/html&gt;</pre>

  </div>

  <div class="example">

   <p>This next document fragment, intended to represent the heading
   of a corporate site, is similarly non-conforming because the second
   line is not intended to be a heading of a subsection, but merely a
   subheading or subtitle (a subordinate heading for the same
   section).</p>

   <pre class="bad">&lt;body&gt;
 &lt;h1&gt;ABC Company&lt;/h1&gt;
 &lt;h2&gt;Leading the way in widget design since 1432&lt;/h2&gt;
 ...</pre>

   <p>The <code><a href="the-hgroup-element.html#the-hgroup-element">hgroup</a></code> element is intended for these kinds of
   situations:</p>

   <pre>&lt;body&gt;
 &lt;hgroup&gt;
  &lt;h1&gt;ABC Company&lt;/h1&gt;
  &lt;h2&gt;Leading the way in widget design since 1432&lt;/h2&gt;
 &lt;/hgroup&gt;
 ...</pre>

  </div>

  <p>Authors must not use elements, attributes, or attribute values
  that are not permitted by this specification or <a href="infrastructure.html#other-applicable-specifications">other
  applicable specifications</a>, as doing so makes it significantly
  harder for the language to be extended in the future.</p>

  <div class="example">

   <p>In the next example, there is a non-conforming attribute value
   ("carpet") and a non-conforming attribute ("texture"), which
   is not permitted by this specification:</p>

   <pre class="bad">&lt;label&gt;Carpet: &lt;input type="carpet" name="c" texture="deep pile"&gt;&lt;/label&gt;</pre>

   <p>Here would be an alternative and correct way to mark this up:</p>

   <pre>&lt;label&gt;Carpet: &lt;input type="text" class="carpet" name="c" data-texture="deep pile"&gt;&lt;/label&gt;</pre>

  </div>

  <p>Through scripting and using other mechanisms, the values of
  attributes, text, and indeed the entire structure of the document
  may change dynamically while a user agent is processing it. The
  semantics of a document at an instant in time are those represented
  by the state of the document at that instant in time, and the
  semantics of a document can therefore change over time. User agents
  <span class="impl">must</span> update their presentation of the
  document as this occurs.</p>

  <p class="example">HTML has a <code><a href="the-progress-element.html#the-progress-element">progress</a></code> element that
  describes a progress bar. If its "value" attribute is dynamically
  updated by a script, the UA would update the rendering to show the
  progress changing.</p>

  <h4 id="elements-in-the-dom"><span class="secno">3.2.2 </span>Elements in the DOM</h4>

  <p>The nodes representing <a href="infrastructure.html#html-elements">HTML elements</a> in the DOM
  <span class="impl">must</span> implement, and expose to scripts, the

  specification. This includes <a href="infrastructure.html#html-elements">HTML elements</a> in <a href="infrastructure.html#xml-documents">XML

  <p>In certain languages, superscripts are part of the typographical
  conventions for some abbreviations.</p>

  <div class="example">
   <pre>&lt;p&gt;The most beautiful women are
&lt;span lang="fr"&gt;&lt;abbr&gt;M&lt;sup&gt;lle&lt;/sup&gt;&lt;/abbr&gt; Gwendoline&lt;/span&gt; and
&lt;span lang="fr"&gt;&lt;abbr&gt;M&lt;sup&gt;me&lt;/sup&gt;&lt;/abbr&gt; Denise&lt;/span&gt;.&lt;/p&gt;</pre>
  </div>

  <p>The <code><a href="#the-sub-and-sup-elements">sub</a></code> element can be used inside a
  <code><a href="the-var-element.html#the-var-element">var</a></code> element, for variables that have subscripts.</p>

  <div class="example">

   <p>Here, the <code><a href="#the-sub-and-sup-elements">sub</a></code> element is used to represents the
   subscript that identifies the variable in a family of
   variables:</p>

   <pre>&lt;p&gt;The coordinate of the &lt;var&gt;i&lt;/var&gt;th point is
(&lt;var&gt;x&lt;sub&gt;&lt;var&gt;i&lt;/var&gt;&lt;/sub&gt;&lt;/var&gt;, &lt;var&gt;y&lt;sub&gt;&lt;var&gt;i&lt;/var&gt;&lt;/sub&gt;&lt;/var&gt;).
For example, the 10th point has coordinate
(&lt;var&gt;x&lt;sub&gt;10&lt;/sub&gt;&lt;/var&gt;, &lt;var&gt;y&lt;sub&gt;10&lt;/sub&gt;&lt;/var&gt;).&lt;/p&gt;</pre>
  </div>

  <p>Mathematical expressions often use subscripts and superscripts.
  Authors are encouraged to use MathML for marking up mathematics, but
  authors may opt to use <code><a href="#the-sub-and-sup-elements">sub</a></code> and <code><a href="#the-sub-and-sup-elements">sup</a></code> if
  detailed mathematical markup is not desired. <a href="references.html#refsMATHML">[MATHML]</a></p>

  <div class="example">
   <pre>&lt;var&gt;E&lt;/var&gt;=&lt;var&gt;m&lt;/var&gt;&lt;var&gt;c&lt;/var&gt;&lt;sup&gt;2&lt;/sup&gt;</pre>
   <pre>f(&lt;var&gt;x&lt;/var&gt;, &lt;var&gt;n&lt;/var&gt;) = log&lt;sub&gt;4&lt;/sub&gt;&lt;var&gt;x&lt;/var&gt;&lt;sup&gt;&lt;var&gt;n&lt;/var&gt;&lt;/sup&gt;</pre>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-i-element">i</a></code> element <a href="rendering.html#represents">represents</a> a span of text
  in an alternate voice or mood, or otherwise offset from the normal
  prose in a manner indicating a different quality of text, such as a
  taxonomic designation, a technical term, an idiomatic phrase from
  another language, a thought, or a ship name in Western texts.</p>

  <p>Terms in languages different from the main text should be
  annotated with <code title="attr-lang"><a href="global-attributes.html#attr-lang">lang</a></code> attributes (or,
  in XML, <a href="global-attributes.html#attr-xml-lang" title="attr-xml-lang"><code title="">lang</code>
  attributes in the <span>XML namespace</span></a>).</p>

  <div class="example">
   <p>The examples below show uses of the <code><a href="#the-i-element">i</a></code> element:</p>
   <pre>&lt;p&gt;The &lt;i class="taxonomy"&gt;Felis silvestris catus&lt;/i&gt; is cute.&lt;/p&gt;
&lt;p&gt;The term &lt;i&gt;prose content&lt;/i&gt; is defined above.&lt;/p&gt;
&lt;p&gt;There is a certain &lt;i lang="fr"&gt;je ne sais quoi&lt;/i&gt; in the air.&lt;/p&gt;</pre>
   <p>In the following example, a dream sequence is marked up using
   <code><a href="#the-i-element">i</a></code> elements.</p>
   <pre>&lt;p&gt;Raymond tried to sleep.&lt;/p&gt;
&lt;p&gt;&lt;i&gt;The ship sailed away on Thursday&lt;/i&gt;, he
dreamt. &lt;i&gt;The ship had many people aboard, including a beautiful
princess called Carey. He watched her, day-in, day-out, hoping she
would notice him, but she never did.&lt;/i&gt;&lt;/p&gt;
&lt;p&gt;&lt;i&gt;Finally one night he picked up the courage to speak with
her&#8212;&lt;/i&gt;&lt;/p&gt;
&lt;p&gt;Raymond woke with a start as the fire alarm rang out.&lt;/p&gt;</pre>
  </div>

  <p>Authors can use the <code title="attr-class"><a href="global-attributes.html#classes">class</a></code>
  attribute on the <code><a href="#the-i-element">i</a></code> element to identify why the element
  is being used, so that if the style of a particular use (e.g. dream
  sequences as opposed to taxonomic terms) is to be changed at a later
  date, the author doesn't have to go through the entire document (or
  series of related documents) annotating each use.</p>

  <p>Authors are encouraged to consider whether other elements might
  be more applicable than the <code><a href="#the-i-element">i</a></code> element, for instance the
  <code><a href="the-em-element.html#the-em-element">em</a></code> element for marking up stress emphasis, or the
  <code><a href="the-dfn-element.html#the-dfn-element">dfn</a></code> element to mark up the defining instance of a
  term.</p>

  <p class="note">Style sheets can be used to format <code><a href="#the-i-element">i</a></code>
  elements, just like any other element can be restyled. Thus, it is
  not the case that content in <code><a href="#the-i-element">i</a></code> elements will
  necessarily be italicized.</p>

  <h4 id="introduction-1"><span class="secno">4.10.1 </span>Introduction</h4>

  <p><i>This section is non-normative.</i></p>
  <p>A form is a component of a Web page that has form controls, such
  as text fields, buttons, checkboxes, range controls, or color
  pickers. A user can interact with such a form, providing data that
  can then be sent to the server for further processing (e.g.
  returning the results of a search or calculation). No client-side
  scripting is needed in many cases, though an API is available so
  that scripts can augment the user experience or use forms for
  purposes other than submitting data to a server.</p>

  <p>Writing a form consists of several steps, which can be performed
  in any order: writing the user interface, implementing the
  server-side processing, and configuring the user interface to
  communicate with the server.</p>


  <h5 id="writing-a-form's-user-interface"><span class="secno">4.10.1.1 </span>Writing a form's user interface</h5>

  <p><i>This section is non-normative.</i></p>
  <p>For the purposes of this brief introduction, we will create a
  pizza ordering form.</p>

  <p>Any form starts with a <code><a href="the-form-element.html#the-form-element">form</a></code> element, inside which
  are placed the controls. Most controls are represented by the
  <code><a href="the-input-element.html#the-input-element">input</a></code> element, which by default provides a one-line
  text field. To label a control, the <code><a href="the-label-element.html#the-label-element">label</a></code> element is
  used; the label text and the control itself go inside the
  <code><a href="the-label-element.html#the-label-element">label</a></code> element. Each part of a form is considered a
  <a href="content-models.html#paragraph">paragraph</a>, and is typically separated from other parts
  using <code><a href="the-p-element.html#the-p-element">p</a></code> elements. Putting this together, here is how
  one might ask for the customer's name:</p>

  <pre><strong>&lt;form&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input&gt;&lt;/label&gt;&lt;/p&gt;
&lt;/form&gt;</strong></pre>

  <p>To let the user select the size of the pizza, we can use a set of
  radio buttons. Radio buttons also use the <code><a href="the-input-element.html#the-input-element">input</a></code>
  element, this time with a <code title="attr-input-type"><a href="the-input-element.html#attr-input-type">type</a></code>
  attribute with the value <code title="attr-input-type-radio"><a href="states-of-the-type-attribute.html#radio-button-state-(type=radio)">radio</a></code>. To make the radio
  buttons work as a group, they are given a common name using the
  <code title="attr-fe-name"><a href="attributes-common-to-form-controls.html#attr-fe-name">name</a></code> attribute. To group a batch
  of controls together, such as, in this case, the radio buttons, one
  can use the <code><a href="the-fieldset-element.html#the-fieldset-element">fieldset</a></code> element. The title of such a group
  of controls is given by the first element in the
  <code><a href="the-fieldset-element.html#the-fieldset-element">fieldset</a></code>, which has to be a <code><a href="the-legend-element.html#the-legend-element">legend</a></code>
  element.</p>

  <pre>&lt;form&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input&gt;&lt;/label&gt;&lt;/p&gt;
<strong> &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;</strong>
&lt;/form&gt;</pre>

  <p class="note">Changes from the previous step are highlighted.</p>

  <p>To pick toppings, we can use checkboxes. These use the
  <code><a href="the-input-element.html#the-input-element">input</a></code> element with a <code title="attr-input-type"><a href="the-input-element.html#attr-input-type">type</a></code> attribute with the value <code title="attr-input-type-checkbox"><a href="states-of-the-type-attribute.html#checkbox-state-(type=checkbox)">checkbox</a></code>:</p>

  <pre>&lt;form&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
<strong> &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Bacon &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Extra Cheese &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Onion &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;</strong>
&lt;/form&gt;</pre>

  <p>The pizzeria for which this form is being written is always
  making mistakes, so it needs a way to contact the customer. For this
  purpose, we can use form controls specifically for telephone numbers
  (<code><a href="the-input-element.html#the-input-element">input</a></code> elements with their <code title="attr-input-type"><a href="the-input-element.html#attr-input-type">type</a></code> attribute set to <code title="attr-input-type-tel"><a href="states-of-the-type-attribute.html#telephone-state-(type=tel)">tel</a></code>) and e-mail addresses
  (<code><a href="the-input-element.html#the-input-element">input</a></code> elements with their <code title="attr-input-type"><a href="the-input-element.html#attr-input-type">type</a></code> attribute set to <code title="attr-input-type-email"><a href="states-of-the-type-attribute.html#e-mail-state-(type=email)">email</a></code>):</p>

  <pre>&lt;form&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input&gt;&lt;/label&gt;&lt;/p&gt;
<strong> &lt;p&gt;&lt;label&gt;Telephone: &lt;input type=tel&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;E-mail address: &lt;input type=email&gt;&lt;/label&gt;&lt;/p&gt;</strong>
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Bacon &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Extra Cheese &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Onion &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
&lt;/form&gt;</pre>

  <p>We can use an <code><a href="the-input-element.html#the-input-element">input</a></code> element with its <code title="attr-input-type"><a href="the-input-element.html#attr-input-type">type</a></code> attribute set to <code title="attr-input-type-time"><a href="states-of-the-type-attribute.html#time-state-(type=time)">time</a></code> to ask for a delivery
  time. Many of these form controls have attributes to control exactly
  what values can be specified; in this case, three attributes of
  particular interest are <code title="attr-input-min"><a href="common-input-element-attributes.html#attr-input-min">min</a></code>,
  <code title="attr-input-max"><a href="common-input-element-attributes.html#attr-input-max">max</a></code>, and <code title="attr-input-step"><a href="common-input-element-attributes.html#attr-input-step">step</a></code>. These set the minimum time, the
  maximum time, and the interval between allowed values (in
  seconds). This pizzeria only delivers between 11am and 9pm, and
  doesn't promise anything better than 15 minute increments, which we
  can mark up as follows:</p>

  <pre>&lt;form&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Telephone: &lt;input type=tel&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;E-mail address: &lt;input type=email&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Bacon &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Extra Cheese &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Onion &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
<strong> &lt;p&gt;&lt;label&gt;Preferred delivery time: &lt;input type=time min="11:00" max="21:00" step="900"&gt;&lt;/label&gt;&lt;/p&gt;</strong>
&lt;/form&gt;</pre>

  <p>The <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> element can be used to provide a
  free-form text field. In this instance, we are going to use it to
  provide a space for the customer to give delivery instructions:</p>

  <pre>&lt;form&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Telephone: &lt;input type=tel&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;E-mail address: &lt;input type=email&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Bacon &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Extra Cheese &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Onion &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;p&gt;&lt;label&gt;Preferred delivery time: &lt;input type=time min="11:00" max="21:00" step="900"&gt;&lt;/label&gt;&lt;/p&gt;
<strong> &lt;p&gt;&lt;label&gt;Delivery instructions: &lt;textarea&gt;&lt;/textarea&gt;&lt;/label&gt;&lt;/p&gt;</strong>
&lt;/form&gt;</pre>

  <p>Finally, to make the form submittable we use the
  <code><a href="the-button-element.html#the-button-element">button</a></code> element:</p>

  <pre>&lt;form&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Telephone: &lt;input type=tel&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;E-mail address: &lt;input type=email&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Bacon &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Extra Cheese &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Onion &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;p&gt;&lt;label&gt;Preferred delivery time: &lt;input type=time min="11:00" max="21:00" step="900"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Delivery instructions: &lt;textarea&gt;&lt;/textarea&gt;&lt;/label&gt;&lt;/p&gt;
<strong> &lt;p&gt;&lt;button&gt;Submit order&lt;/button&gt;&lt;/p&gt;</strong>
&lt;/form&gt;</pre>

  attribute is specified on the <code><a href="the-form-element.html#the-form-element">form</a></code> element. This
  doesn't specify how the form data is encoded, though; to specify
  that, you use the <code title="attr-fs-enctype"><a href="form-submission.html#attr-fs-enctype">enctype</a></code>
  attribute. You also have to specify the <a href="urls.html#url">URL</a> of the
  service that will handle the submitted data, using the <code title="attr-fs-action"><a href="form-submission.html#attr-fs-action">action</a></code> attribute.</p>

  <p>For each form control you want submitted, you then have to give a
  name that will be used to refer to the data in the submission. We
  already specified the name for the group of radio buttons; the same
  attribute (<code title="attr-fe-name"><a href="attributes-common-to-form-controls.html#attr-fe-name">name</a></code>) also specifies
  the submission name. Radio buttons can be distinguished from each
  other in the submission by giving them different values, using the
  <code title="attr-input-value"><a href="the-input-element.html#attr-input-value">value</a></code> attribute.</p>

  <p>Multiple controls can have the same name; for example, here we
  give all the checkboxes the same name, and the server distinguishes
  which checkbox was checked by seeing which values are submitted with
  that name &#8212; like the radio buttons, they are also given unique
  values with the <code title="attr-input-value"><a href="the-input-element.html#attr-input-value">value</a></code>
  attribute.</p>

  <p>Given the settings in the previous section, this all becomes:</p>

  <pre>&lt;form<strong> method="post"
      enctype="application/x-www-form-urlencoded"
      action="https://pizza.example.com/order.cgi"</strong>&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input<strong> name="custname"</strong>&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Telephone: &lt;input type=tel<strong> name="custtel"</strong>&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;E-mail address: &lt;input type=email<strong> name="custemail"</strong>&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size<strong> value="small"</strong>&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size<strong> value="medium"</strong>&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size<strong> value="large"</strong>&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox<strong> name="topping" value="bacon"</strong>&gt; Bacon &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox<strong> name="topping" value="cheese"</strong>&gt; Extra Cheese &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox<strong> name="topping" value="onion"</strong>&gt; Onion &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox<strong> name="topping" value="mushroom"</strong>&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;p&gt;&lt;label&gt;Preferred delivery time: &lt;input type=time min="11:00" max="21:00" step="900"<strong> name="delivery"</strong>&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Delivery instructions: &lt;textarea<strong> name="comments"</strong>&gt;&lt;/textarea&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;button&gt;Submit order&lt;/button&gt;&lt;/p&gt;
&lt;/form&gt;</pre>

  <p>For example, if the customer entered "Denise Lawrence" as their
  name, "555-321-8642" as their telephone number, did not specify an
  e-mail address, asked for a medium-sized pizza, selected the Extra
  Cheese and Mushroom toppings, entered a delivery time of 7pm, and
  left the delivery instructions text field blank, the user agent
  would submit the following to the online Web service:</p>

  <pre>custname=Denise+Lawrence&amp;custtel=555-321-8624&amp;custemail=&amp;size=medium&amp;topping=cheese&amp;topping=mushroom&amp;delivery=19%3A00&amp;comments=</pre>



  <h5 id="client-side-form-validation"><span class="secno">4.10.1.4 </span>Client-side form validation</h5>

  <p><i>This section is non-normative.</i></p>
  <p>Forms can be annotated in such a way that the user agent will
  check the user's input before the form is submitted. The server
  still has to verify the input is valid (since hostile users can
  easily bypass the form validation), but it allows the user to avoid
  the wait incurred by having the server be the sole checker of the
  user's input.</p>

  <p>The simplest annotation is the <code title="attr-input-required"><a href="common-input-element-attributes.html#attr-input-required">required</a></code> attribute, which can be
  specified on <code><a href="the-input-element.html#the-input-element">input</a></code> elements to indicate that the form
  is not to be submitted until a value is given. By adding this
  attribute to the customer name and delivery time fields, we allow
  the user agent to notify the user when the user submits the form
  without filling in those fields:</p>

  <pre>&lt;form method="post"
      enctype="application/x-www-form-urlencoded"
      action="https://pizza.example.com/order.cgi"&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input name="custname"<strong> required</strong>&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Telephone: &lt;input type=tel name="custtel"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;E-mail address: &lt;input type=email name="custemail"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size value="small"&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size value="medium"&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size value="large"&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox name="topping" value="bacon"&gt; Bacon &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox name="topping" value="cheese"&gt; Extra Cheese &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox name="topping" value="onion"&gt; Onion &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox name="topping" value="mushroom"&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;p&gt;&lt;label&gt;Preferred delivery time: &lt;input type=time min="11:00" max="21:00" step="900" name="delivery"<strong> required</strong>&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Delivery instructions: &lt;textarea name="comments"&gt;&lt;/textarea&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;button&gt;Submit order&lt;/button&gt;&lt;/p&gt;
&lt;/form&gt;</pre>

  <p>It is also possible to limit the length of the input, using the
  <code title="attr-fe-maxlength"><a href="attributes-common-to-form-controls.html#attr-fe-maxlength">maxlength</a></code> attribute. By
  adding this to the <code><a href="the-textarea-element.html#the-textarea-element">textarea</a></code> element, we can limit users
  to 1000 characters, preventing them from writing huge essays to the
  busy delivery drivers instead of staying focused and to the
  point:</p>

  <pre>&lt;form method="post"
      enctype="application/x-www-form-urlencoded"
      action="https://pizza.example.com/order.cgi"&gt;
 &lt;p&gt;&lt;label&gt;Customer name: &lt;input name="custname" required&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;Telephone: &lt;input type=tel name="custtel"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;p&gt;&lt;label&gt;E-mail address: &lt;input type=email name="custemail"&gt;&lt;/label&gt;&lt;/p&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Size &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size value="small"&gt; Small &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size value="medium"&gt; Medium &lt;/label&gt;&lt;/p&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=radio name=size value="large"&gt; Large &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;
 &lt;fieldset&gt;
  &lt;legend&gt; Pizza Toppings &lt;/legend&gt;
  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox name="topping" value="bacon"&gt; Bacon &lt;/label&gt;&lt;/p&gt;

  &lt;p&gt;&lt;label&gt; &lt;input type=checkbox name="topping" value="mushroom"&gt; Mushroom &lt;/label&gt;&lt;/p&gt;
 &lt;/fieldset&gt;

&lt;/form&gt;</pre>


  <h5 id="input-author-notes"><span class="secno">4.10.1.5 </span>Date, time, and number formats</h5>

  <p><i>This section is non-normative.</i></p>
  <p>In this pizza delivery example, the times are specified in the
  format "HH:MM": two digits for the hour, in 24-hour format, and two
  digits for the time. (Seconds could also be specified, though they
  are not necessary in this example.)</p>

  <p>In some locales, however, times are often expressed differently
  when presented to users. For example, in the United States, it is
  still common to use the 12-hour clock with an am/pm indicator, as in
  "2pm". In France, it is common to separate the hours from the
  minutes using an "h" character, as in "14h00".</p>

  <p>Similar issues exist with dates, with the added complication that
  even the order of the components is not always consistent &#8212;
  for example, in Cyprus the first of February 2003 would typically be
  written "1/2/03", while that same date in Japan would typically be
  written as "2003&#24180;02&#26376;01&#26085;" &#8212; and even with
  numbers, where locales differ, for example, in what punctuation is
  used as the decimal separator and the thousands separator.</p>

  <p>It therefore is important to distinguish the time, date, and
  number formats used in HTML and in form submissions, which are
  always the formats defined in this specification (and based on the
  well-established ISO 8601 standard for computer-readable date and
  time formats), from the time, date, and number formats presented to
  the user by the browser and accepted as input from the user by the
  browser.</p>

  <p>The format used "on the wire", i.e. in HTML markup and in form
  submissions, is intended to be computer-readable and consistent
  irrespective of the user's locale. Dates, for instance, are always
  written in the format "YYYY-MM-DD", as in "2003-02-01". Users are
  not expected to ever see this format.</p>

  <p>The time, date, or number given by the page in the wire format is
  then translated to the user's preferred presentation (based on user
  preferences or on the locale of the page itself), before being
  displayed to the user. Similarly, after the user inputs a time,
  date, or number using their preferred format, the user agent
  converts it back to the wire format before putting it in the DOM or
  submitting it.</p>

  <p>This allows scripts in pages and on servers to process times,
  dates, and numbers in a consistent manner without needing to support
  dozens of different formats, while still supporting the users'
  needs.</p>

  </dl><!--REMOVE-TOPIC:DOM APIs--><p>The <code><a href="#the-canvas-element">canvas</a></code> element provides scripts with a
  resolution-dependent bitmap canvas, which can be used for rendering
  graphs, game graphics, art, or other visual images on the fly.</p>

  <p>Authors should not use the <code><a href="#the-canvas-element">canvas</a></code> element in a
  document when a more suitable element is available. For example, it
  is inappropriate to use a <code><a href="#the-canvas-element">canvas</a></code> element to render a
  page heading: if the desired presentation of the heading is
  graphically intense, it should be marked up using appropriate
  elements (typically <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code>) and then styled using CSS and
  supporting technologies such as XBL.</p>

  <p>When authors use the <code><a href="#the-canvas-element">canvas</a></code> element, they must also
  provide content that, when presented to the user, conveys

  <p>The <code><a href="#the-canvas-element">canvas</a></code> element has two attributes to control the

  <p>The intrinsic dimensions of the <code><a href="#the-canvas-element">canvas</a></code> element equal

  <div class="impl">

  <p>The size of the coordinate space does not necessarily represent

  <h5 id="color-spaces-and-color-correction"><span class="secno">4.8.11.1 </span>Color spaces and color correction</h5>

  <p>The <code><a href="#the-canvas-element">canvas</a></code> APIs must perform color correction at
  only two points: when rendering images with their own gamma
  correction and color space information onto the canvas, to convert
  the image to the color space used by the canvas (e.g. using the 2D
  Context's <code title="dom-context-2d-drawImage">drawImage()</code>
  method with an <code><a href="the-img-element.html#htmlimageelement">HTMLImageElement</a></code> object), and when
  rendering the actual canvas bitmap to the output device.</p>

  <p class="note">Thus, in the 2D context, colors used to draw shapes
  onto the canvas will exactly match colors obtained through the <code title="dom-context-2d-getImageData">getImageData()</code>
  method.</p>

  <p>The <code title="dom-canvas-toDataURL"><a href="#dom-canvas-todataurl">toDataURL()</a></code> method
  must not include color space information in the resource
  returned. Where the output format allows it, the color of pixels in
  resources created by <code title="dom-canvas-toDataURL"><a href="#dom-canvas-todataurl">toDataURL()</a></code> must match those
  returned by the <code title="dom-context-2d-getImageData">getImageData()</code>
  method.</p>

  <p>In user agents that support CSS, the color space used by a
  <code><a href="#the-canvas-element">canvas</a></code> element must match the color space used for
  processing any colors for that element in CSS.</p>

  <p>The gamma correction and color space information of images must
  be handled in such a way that an image rendered directly using an
  <code><a href="the-img-element.html#the-img-element">img</a></code> element would use the same colors as one painted on
  a <code><a href="#the-canvas-element">canvas</a></code> element that is then itself
  rendered. Furthermore, the rendering of images that have no color
  correction information (such as those returned by the <code title="dom-canvas-toDataURL"><a href="#dom-canvas-todataurl">toDataURL()</a></code> method) must be
  rendered with no color correction.</p>

  <p class="note">Thus, in the 2D context, calling the <code title="dom-context-2d-drawImage">drawImage()</code> method to render
  the output of the <code title="dom-canvas-toDataURL"><a href="#dom-canvas-todataurl">toDataURL()</a></code> method to the
  canvas, given the appropriate dimensions, has no visible effect.</p>

  boxes are to be aligned.</p>

  <p>If the value is a &lt;position&gt;, the alignment point is the point
  given by the value, which must be interpreted relative to the
  element's first rendered box's margin box. Percentages must be
  calculated relative to the element's first rendered box's margin box
  (specifically, its width for the horizontal position and its height
  for the vertical position). <a href="references.html#refsCSSVALUES">[CSSVALUES]</a>
  <a href="references.html#refsCSS">[CSS]</a></p>

  <p>If the value is the keyword 'none', then no explicit alignment
  point is defined. The user agent will pick an alignment point
  automatically if necessary (as described in the definition of the
  <code title="dom-dialog-open"><a href="#dom-dialog-open">open()</a></code> method above).</p>

  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-u-element">u</a></code> element <a href="rendering.html#represents">represents</a> a span of text
  with an unarticulated, though explicitly rendered, non-textual
  annotation, such as labeling the text as being a proper name in
  Chinese text (a Chinese proper name mark), or labeling the text as
  being misspelt.</p>

  <p>In most cases, another element is likely to be more appropriate:
  for marking stress emphasis, the <code><a href="the-em-element.html#the-em-element">em</a></code> element should be
  used; for marking key words or phrases either the <code><a href="the-b-element.html#the-b-element">b</a></code>
  element or the <code><a href="the-mark-element.html#the-mark-element">mark</a></code> element should be used, depending
  on the context; for marking book titles, the <code><a href="the-cite-element.html#the-cite-element">cite</a></code>
  element should be used<!-- even for the Chinese wavy underline 'book
  title mark' -->; for labeling text with explicit textual
  annotations, the <code><a href="the-ruby-element.html#the-ruby-element">ruby</a></code> element should be used; for
  labeling ship names in Western texts, the <code><a href="the-i-element.html#the-i-element">i</a></code> element
  should be used.</p>

  <p class="note">The default rendering of the <code><a href="#the-u-element">u</a></code> element
  in visual presentations clashes with the conventional rendering of
  hyperlinks (underlining). Authors are encouraged to avoid using the
  <code><a href="#the-u-element">u</a></code> element where it could be confused for a
  hyperlink.</p>

  <p>The <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code>&#8211;<code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h6</a></code> elements and the
  <code><a href="the-hgroup-element.html#the-hgroup-element">hgroup</a></code> element are headings.</p>

  <p>The first element of <a href="content-models.html#heading-content-0">heading content</a> in an element
  of <a href="content-models.html#sectioning-content-0">sectioning content</a> <a href="rendering.html#represents">represents</a> the
  heading for that section. Subsequent headings of equal or higher
  <a href="the-aside-element.html#rank">rank</a> start new (implied) sections, headings of lower
  <a href="the-aside-element.html#rank">rank</a> start implied subsections that are part of the
  previous one. In both cases, the element <a href="rendering.html#represents">represents</a> the
  heading of the implied section.</p>

  <p>Certain elements are said to be <dfn id="sectioning-root" title="sectioning
  root">sectioning roots</dfn>, including <code><a href="the-blockquote-element.html#the-blockquote-element">blockquote</a></code> and
  <code><a href="the-td-element.html#the-td-element">td</a></code> elements. These elements can have their own
  outlines, but the sections and headings inside these elements do not
  contribute to the outlines of their ancestors.</p>

  </ul><!-- a root element isn't a sectioning root. This means, for
  instance, that you don't get an outline if you just have a random
  XML file with <html:h1> elements in it. Other vocabs need to define
  what their sectioning root is. --><p><a href="content-models.html#sectioning-content-0">Sectioning content</a> elements are always considered
  subsections of their nearest ancestor <a href="#sectioning-root">sectioning root</a>
  or their nearest ancestor element of <a href="content-models.html#sectioning-content-0">sectioning
  content</a>, whichever is nearest, regardless of what implied
  sections other headings may have created.</p>

  <div class="example">
   <p>For the following fragment:</p>
   <pre>&lt;body&gt;
 &lt;h1&gt;Foo&lt;/h1&gt;
 &lt;h2&gt;Bar&lt;/h2&gt;
 &lt;blockquote&gt;
  &lt;h3&gt;Bla&lt;/h3&gt;
 &lt;/blockquote&gt;
 &lt;p&gt;Baz&lt;/p&gt;
 &lt;h2&gt;Quux&lt;/h2&gt;
 &lt;section&gt;
  &lt;h3&gt;Thud&lt;/h3&gt;
 &lt;/section&gt;
 &lt;p&gt;Grunt&lt;/p&gt;
&lt;/body&gt;</pre>
   <p>...the structure would be:</p>
   <ol><li>
     Foo (heading of explicit <code><a href="the-body-element.html#the-body-element">body</a></code> section, containing the "Grunt" paragraph)
     <ol><li>
       Bar (heading starting implied section, containing a block quote and the "Baz" paragraph)
      </li>
      <li>
       Quux (heading starting implied section with no content other than the heading itself)
      </li>
      <li>
       Thud (heading of explicit <code><a href="the-section-element.html#the-section-element">section</a></code> section)
      </li>
     </ol></li>
   </ol><p>Notice how the <code><a href="the-section-element.html#the-section-element">section</a></code> ends the earlier implicit
   section so that a later paragraph ("Grunt") is back at the top
   level.</p>
  </div>

  <p>Sections may contain headings of any <a href="the-aside-element.html#rank">rank</a>, but
  authors are strongly encouraged to either use only <code><a href="the-aside-element.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements">h1</a></code>
  elements, or to use elements of the appropriate <a href="the-aside-element.html#rank">rank</a>
  for the section's nesting level.</p>

  <p>Authors are also encouraged to explicitly wrap sections in
  elements of <a href="content-models.html#sectioning-content-0">sectioning content</a>, instead of relying on
  the implicit sections generated by having multiple headings in one
  element of <a href="content-models.html#sectioning-content-0">sectioning content</a>.</p>

  <div class="example">
   <p>For example, the following is correct:</p>

   <pre>&lt;body&gt;
 &lt;h4&gt;Apples&lt;/h4&gt;
 &lt;p&gt;Apples are fruit.&lt;/p&gt;
 &lt;section&gt;
  &lt;h2&gt;Taste&lt;/h2&gt;
  &lt;p&gt;They taste lovely.&lt;/p&gt;
  &lt;h6&gt;Sweet&lt;/h6&gt;
  &lt;p&gt;Red apples are sweeter than green ones.&lt;/p&gt;
  &lt;h1&gt;Color&lt;/h1&gt;
  &lt;p&gt;Apples come in various colors.&lt;/p&gt;
 &lt;/section&gt;
&lt;/body&gt;</pre>

   <p>However, the same document would be more clearly expressed
   as:</p>

   <pre>&lt;body&gt;
 &lt;h1&gt;Apples&lt;/h1&gt;
 &lt;p&gt;Apples are fruit.&lt;/p&gt;
 &lt;section&gt;
  &lt;h2&gt;Taste&lt;/h2&gt;
  &lt;p&gt;They taste lovely.&lt;/p&gt;
  &lt;section&gt;
   &lt;h3&gt;Sweet&lt;/h3&gt;
   &lt;p&gt;Red apples are sweeter than green ones.&lt;/p&gt;
  &lt;/section&gt;
 &lt;/section&gt;
 &lt;section&gt;
  &lt;h2&gt;Color&lt;/h2&gt;
  &lt;p&gt;Apples come in various colors.&lt;/p&gt;
 &lt;/section&gt;
&lt;/body&gt;</pre>

   <p>Both of the documents above are semantically identical and would
   produce the same outline in compliant user agents.</p>

   <p>This third example is also semantically identical, and might be
   easier to maintain (e.g. if sections are often moved around in
   editing):</p>

   <pre>&lt;body&gt;
 &lt;h1&gt;Apples&lt;/h1&gt;
 &lt;p&gt;Apples are fruit.&lt;/p&gt;
 &lt;section&gt;
  &lt;h1&gt;Taste&lt;/h1&gt;
  &lt;p&gt;They taste lovely.&lt;/p&gt;
  &lt;section&gt;
   &lt;h1&gt;Sweet&lt;/h1&gt;
   &lt;p&gt;Red apples are sweeter than green ones.&lt;/p&gt;
  &lt;/section&gt;
 &lt;/section&gt;
 &lt;section&gt;
  &lt;h1&gt;Color&lt;/h1&gt;
  &lt;p&gt;Apples come in various colors.&lt;/p&gt;
 &lt;/section&gt;
&lt;/body&gt;</pre>

   <p>This final example would need explicit style rules to be
   rendered well in legacy browsers. Legacy browsers without CSS
   support would render all the headings as top-level headings.</p>

  <h5 id="outlines"><span class="secno">4.4.11.1 </span>Creating an outline</h5>

  <div class="impl">

  <!-- v2 idea: It would be nice if there was a way to use this to
  autogenerate a table of contents or some such -->

  <p>This section defines an algorithm for creating an outline for a
  <a href="content-models.html#sectioning-content-0">sectioning content</a> element or a <a href="#sectioning-root">sectioning
  root</a> element. It is defined in terms of a walk over the nodes
  of a DOM tree, in tree order, with each node being visited when it
  is <i>entered</i> and when it is <i>exited</i> during the walk.</p>

  </div>

  <p>The <dfn id="outline">outline</dfn> for a <a href="content-models.html#sectioning-content-0">sectioning content</a>
  element or a <a href="#sectioning-root">sectioning root</a> element consists of a list
  of one or more potentially nested <a href="#concept-section" title="concept-section">sections</a>. A <dfn id="concept-section" title="concept-section">section</dfn> is a container that
  corresponds to some nodes in the original DOM tree. Each section can
  have one heading associated with it, and can contain any number of
  further nested sections. <span class="impl">The algorithm for the
  outline also associates each node in the DOM tree with a particular
  section and potentially a heading.</span> (The sections in the
  outline aren't <code><a href="the-section-element.html#the-section-element">section</a></code> elements, though some may
  correspond to such elements &#8212; they are merely conceptual
  sections.)</p>

  <div class="example">

   <p>The following markup fragment:</p>

   <pre>&lt;body&gt;
 &lt;h1&gt;A&lt;/h1&gt;
 &lt;p&gt;B&lt;/p&gt;
 &lt;h2&gt;C&lt;/h2&gt;
 &lt;p&gt;D&lt;/p&gt;
 &lt;h2&gt;E&lt;/h2&gt;
 &lt;p&gt;F&lt;/p&gt;
&lt;/body&gt;</pre>

   <p>...results in the following outline being created for the
   <code><a href="the-body-element.html#the-body-element">body</a></code> node (and thus the entire document):</p>

   <ol class="brief"><li>
     <p>Section created for <code><a href="the-body-element.html#the-body-element">body</a></code> node.</p>

       <p>Also associated with paragraph "D".</p>
       <p>No nested sections.</p>

    </dl><p id="associatedSection">In addition, whenever the walk exits a
    node, after doing the steps above, if the node is not associated
    with a <a href="#concept-section" title="concept-section">section</a> yet, associate
    the node with the <a href="#concept-section" title="concept-section">section</a>

  </ol><p>The tree of sections created by the algorithm above, or a proper
  subset thereof, must be used when generating document outlines, for
  example when generating tables of contents.</p>

  <p>The outline created for <a href="dom.html#the-body-element-0">the body element</a> of a
  <code><a href="dom.html#document">Document</a></code> is the <a href="#outline">outline</a> of the entire
  document.</p>

  <p>When creating an interactive table of contents, entries should
  jump the user to the relevant <a href="content-models.html#sectioning-content-0">sectioning content</a>
  element, if the <a href="#concept-section" title="concept-section">section</a> was
  created for a real element in the original document, or to the
  relevant <a href="content-models.html#heading-content-0">heading content</a> element, if the <a href="#concept-section" title="concept-section">section</a> in the tree was generated for
  a heading in the above process.</p>

  <p class="note">Selecting the first <a href="#concept-section" title="concept-section">section</a> of the document therefore
  always takes the user to the top of the document, regardless of
  where the first heading in the <code><a href="the-body-element.html#the-body-element">body</a></code> is to be found.</p>

  <p>The <dfn id="outline-depth">outline depth</dfn> of a <a href="content-models.html#heading-content-0">heading content</a>
  element associated with a <a href="#concept-section" title="concept-section">section</a> <var title="">section</var>
  is the number of <a href="#concept-section" title="concept-section">sections</a> that
  are ancestors of <var title="">section</var> in the outermost
  <a href="#outline">outline</a> that <var title="">section</var> finds itself
  in when the <a href="#outline" title="outline">outlines</a> of its
  <code><a href="dom.html#document">Document</a></code>'s elements are created, plus 1. The
  <a href="#outline-depth">outline depth</a> of a <a href="content-models.html#heading-content-0">heading content</a> element
  not associated with a <a href="#concept-section" title="concept-section">section</a>
  is 1.</p>

  <p>User agents should provide default headings for sections that do
  not have explicit section headings.</p>

  <div class="example">

   <p>Consider the following snippet:</p>

   <pre>&lt;body&gt;
 &lt;nav&gt;
  &lt;p&gt;&lt;a href="/"&gt;Home&lt;/a&gt;&lt;/p&gt;
 &lt;/nav&gt;
 &lt;p&gt;Hello world.&lt;/p&gt;
 &lt;aside&gt;
  &lt;p&gt;My cat is cute.&lt;/p&gt;
 &lt;/aside&gt;
&lt;/body&gt;</pre>

   <p>Although it contains no headings, this snippet has three
   sections: a document (the <code><a href="the-body-element.html#the-body-element">body</a></code>) with two subsections
   (a <code><a href="the-nav-element.html#the-nav-element">nav</a></code> and an <code><a href="the-aside-element.html#the-aside-element">aside</a></code>). A user agent could
   present the outline as follows:</p>

   <ol class="brief"><li>Untitled document
     <ol><li>Navigation</li>
      <li>Sidebar</li>
     </ol></li>
   </ol><p>These default headings ("Untitled document", "Navigation",
   "Sidebar") are not specified by this specification, and might vary
   with the user's language, the page's language, the user's
   preferences, the user agent implementor's preferences, etc.</p>

  </div>

  <div class="note">

   <p>The following JavaScript function shows how the tree walk could
   be implemented. The <var title="">root</var> argument is the root
   of the tree to walk (either a <a href="content-models.html#sectioning-content-0">sectioning content</a>

  explicitly associate the <code><a href="#the-button-element">button</a></code> element with its
  <a href="association-of-controls-and-forms.html#form-owner">form owner</a>. The <code title="attr-fe-name"><a href="attributes-common-to-form-controls.html#attr-fe-name">name</a></code>
  attribute represents the element's name. The <code title="attr-fe-disabled"><a href="attributes-common-to-form-controls.html#attr-fe-disabled">disabled</a></code> attribute is used to make
  the control non-interactive and to prevent its value from being
  submitted. The <code title="attr-fe-autofocus"><a href="attributes-common-to-form-controls.html#attr-fe-autofocus">autofocus</a></code>
  attribute controls focus. The <code title="attr-fs-formaction"><a href="form-submission.html#attr-fs-formaction">formaction</a></code>, <code title="attr-fs-formenctype"><a href="form-submission.html#attr-fs-formenctype">formenctype</a></code>, <code title="attr-fs-formmethod"><a href="form-submission.html#attr-fs-formmethod">formmethod</a></code>, <code title="attr-fs-formnovalidate"><a href="form-submission.html#attr-fs-formnovalidate">formnovalidate</a></code>, and <code title="attr-fs-formtarget"><a href="form-submission.html#attr-fs-formtarget">formtarget</a></code> attributes are
  <a href="form-submission.html#attributes-for-form-submission">attributes for form submission</a>.</p>

  <p class="note">The <code title="attr-fs-formnovalidate"><a href="form-submission.html#attr-fs-formnovalidate">formnovalidate</a></code> attribute can
  be used to make submit buttons that do not trigger the constraint
  validation.</p>

  <p>The <code title="attr-fs-formaction"><a href="form-submission.html#attr-fs-formaction">formaction</a></code>, <code title="attr-fs-formenctype"><a href="form-submission.html#attr-fs-formenctype">formenctype</a></code>, <code title="attr-fs-formmethod"><a href="form-submission.html#attr-fs-formmethod">formmethod</a></code>, <code title="attr-fs-formnovalidate"><a href="form-submission.html#attr-fs-formnovalidate">formnovalidate</a></code>, and <code title="attr-fs-formtarget"><a href="form-submission.html#attr-fs-formtarget">formtarget</a></code> must not be specified
  if the element's <code title="attr-button-type"><a href="#attr-button-type">type</a></code>
  attribute is not in the <a href="#attr-button-type-submit-state" title="attr-button-type-submit-state">Submit Button</a>
  state.</p>

  <p>The <dfn id="attr-button-value" title="attr-button-value"><code>value</code></dfn>
  attribute gives the element's value for the purposes of form
  submission. The element's <a href="attributes-common-to-form-controls.html#concept-fe-value" title="concept-fe-value">value</a> is the value of the element's
  <code title="attr-button-value"><a href="#attr-button-value">value</a></code> attribute, if there is
  one, or the empty string otherwise.</p>

  <p class="note">A button (and its value) is only included in the
  form submission if the button itself was used to initiate the form
  submission.</p>

  <div class="impl">

  <p>The <dfn id="dom-button-value" title="dom-button-value"><code>value</code></dfn> IDL

   <dd>Uses <code><a href="elements.html#htmlelement">HTMLElement</a></code>.</dd>
  </dl><!--TOPIC:HTML--><p>The <code><a href="#the-cite-element">cite</a></code> element <a href="rendering.html#represents">represents</a> the title
  of a work (e.g.
  a book,
  a paper,
  an essay,
  a poem,
  a score,
  a song,
  a script,
  a film,
  a TV show,
  a game,
  a sculpture,
  a painting,
  a theatre production,
  a play,
  an opera,
  a musical,
  an exhibition,
  a legal case report,
  etc). This can be a work that is being quoted or
  referenced in detail (i.e. a citation), or it can just be a work
  that is mentioned in passing.</p>

  <p>A person's name is not the title of a work &#8212; even if people
  call that person a piece of work &#8212; and the element must
  therefore not be used to mark up people's names. (In some cases, the
  <code><a href="the-b-element.html#the-b-element">b</a></code> element might be appropriate for names; e.g. in a
  gossip article where the names of famous people are keywords
  rendered with a different style to draw attention to them. In other
  cases, if an element is <em>really</em> needed, the
  <code><a href="the-span-element.html#the-span-element">span</a></code> element can be used.)</p>

<!--(some people argue a ship is a work)
  <p>A ship is similarly not a work, and the element must not be used
  to mark up ship names (the <code>i</code> element can be used for
  that purpose).</p>
-->

  <div class="example">

   <p>This next example shows a typical use of the <code><a href="#the-cite-element">cite</a></code>
   element:</p>

   <pre>&lt;p&gt;My favorite book is &lt;cite&gt;The Reality Dysfunction&lt;/cite&gt; by
Peter F. Hamilton. My favorite comic is &lt;cite&gt;Pearls Before
Swine&lt;/cite&gt; by Stephan Pastis. My favorite track is &lt;cite&gt;Jive
Samba&lt;/cite&gt; by the Cannonball Adderley Sextet.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>This is correct usage:</p>

   <pre>&lt;p&gt;According to the Wikipedia article &lt;cite&gt;HTML&lt;/cite&gt;, as it
stood in mid-February 2008, leaving attribute values unquoted is
unsafe. This is obviously an over-simplification.&lt;/p&gt;</pre>

   <p>The following, however, is incorrect usage, as the
   <code><a href="#the-cite-element">cite</a></code> element here is containing far more than the
   title of the work:</p>

   <pre class="bad">&lt;!-- do not copy this example, it is an example of bad usage! --&gt;
&lt;p&gt;According to &lt;cite&gt;the Wikipedia article on HTML&lt;/cite&gt;, as it
stood in mid-February 2008, leaving attribute values unquoted is
unsafe. This is obviously an over-simplification.&lt;/p&gt;</pre>

  </div>

  <div class="example">

   <p>The <code><a href="#the-cite-element">cite</a></code> element is obviously a key part of any
   citation in a bibliography, but it is only used to mark the
   title:</p>

   <pre>&lt;p&gt;&lt;cite&gt;Universal Declaration of Human Rights&lt;/cite&gt;, United Nations,
December 1948. Adopted by General Assembly resolution 217 A (III).&lt;/p&gt;</pre>

  </div>

  <p class="note">A <em>citation</em> is not a <em>quote</em> (for
  which the <code><a href="the-q-element.html#the-q-element">q</a></code> element is appropriate).</p>

  <div class="example">

   <p>This is incorrect usage, because <code><a href="#the-cite-element">cite</a></code> is not for
   quotes:</p>

   <pre class="bad">&lt;p&gt;&lt;cite&gt;This is wrong!&lt;/cite&gt;, said Ian.&lt;/p&gt;</pre>

   <p>This is also incorrect usage, because a person is not a
   work:</p>

   <pre class="bad">&lt;p&gt;&lt;q&gt;This is still wrong!&lt;/q&gt;, said &lt;cite&gt;Ian&lt;/cite&gt;.&lt;/p&gt;</pre>

   <p>The correct usage does not use a <code><a href="#the-cite-element">cite</a></code> element:</p>

   <pre>&lt;p&gt;&lt;q&gt;This is correct&lt;/q&gt;, said Ian.&lt;/p&gt;</pre>

   <p>As mentioned above, the <code><a href="the-b-element.html#the-b-element">b</a></code> element might be relevant
   for marking names as being keywords in certain kinds of
   documents:</p>

   <pre>&lt;p&gt;And then &lt;b&gt;Ian&lt;/b&gt; said &lt;q&gt;this might be right, in a
gossip column, maybe!&lt;/q&gt;.&lt;/p&gt;</pre>

   <p>How a user agent exposes such multi-level headings in user
   interfaces (e.g. in tables of contents or search results) is left
   open to implementors, as it is a user interface issue. The first
   example above could be rendered as:</p>

   <pre>The reality dysfunction: Space is not the only void</pre>

   <p>Alternatively, it could look like this:

   </p><pre>The reality dysfunction (Space is not the only void)</pre>

   <p>In interfaces where a title can be rendered on multiple lines,
   it could be rendered as follows, maybe with the first line in a
   bigger font size:</p>

   <pre>The reality dysfunction
Space is not the only void</pre>

  <h5 id="common-event-behaviors"><span class="secno">4.10.7.5 </span>Common event behaviors</h5>

  <p>When the <dfn id="event-input-input" title="event-input-input"><code>input</code></dfn>
  event applies, any time the user causes the element's <a href="attributes-common-to-form-controls.html#concept-fe-value" title="concept-fe-value">value</a> to change, the user agent must
  <a href="webappapis.html#queue-a-task">queue a task</a> to <a href="webappapis.html#fire-a-simple-event">fire a simple event</a> that
  bubbles named <code title="event-input">input</code> at the
  <code><a href="the-input-element.html#the-input-element">input</a></code> element. User agents may wait for a suitable
  break in the user's interaction before queuing the task; for
  example, a user agent could wait for the user to have not hit a key
  for 100ms, so as to only fire the event when the user pauses,
  instead of continuously for each keystroke.</p> <!-- same text is
  present in the <textarea> section -->

  <p class="example">Examples of a user changing the element's <a href="attributes-common-to-form-controls.html#concept-fe-value" title="concept-fe-value">value</a> would include the user typing
  into a text field, pasting a new value into the field, or undoing an
  edit in that field. Some user interactions do not cause changes to
  the value, e.g. hitting the "delete" key in an empty text field, or
  replacing some text in the field with text from the clipboard that
  happens to be exactly the same text.</p>

  <p>When the <dfn id="event-input-change" title="event-input-change"><code>change</code></dfn> event applies,
  if the element does not have an <a href="content-models.html#activation-behavior">activation behavior</a>
  defined but uses a user interface that involves an explicit commit
  action, then any time the user commits a change to the element's
  <a href="attributes-common-to-form-controls.html#concept-fe-value" title="concept-fe-value">value</a> or list of <a href="states-of-the-type-attribute.html#concept-input-type-file-selected" title="concept-input-type-file-selected">selected files</a>, the
  user agent must <a href="webappapis.html#queue-a-task">queue a task</a> to <a href="webappapis.html#fire-a-simple-event">fire a simple
  event</a> that bubbles named <code title="event-change">change</code> at the <code><a href="the-input-element.html#the-input-element">input</a></code>
  element.</p>

  <p class="example">An example of a user interface with a commit
  action would be a <a href="states-of-the-type-attribute.html#file-upload-state-(type=file)" title="attr-input-type-file">File
  Upload</a> control that consists of a single button that brings
  up a file selection dialog: when the dialog is closed, if that the
  <a href="states-of-the-type-attribute.html#concept-input-type-file-selected" title="concept-input-type-file-selected">file selection</a>
  changed as a result, then the user has committed a new <a href="states-of-the-type-attribute.html#concept-input-type-file-selected" title="concept-input-type-file-selected">file selection</a>.</p>

  <p class="example">Another example of a user interface with a commit
  action would be a <a href="states-of-the-type-attribute.html#date-state-(type=date)" title="attr-input-type-date">Date</a>
  control that allows both text-based user input and user selection
  from a drop-down calendar: while text input might not have an
  explicit commit step, selecting a date from the drop down calendar
  and then dismissing the drop down would be a commit action.</p>

  <p>When the user agent changes the element's <a href="attributes-common-to-form-controls.html#concept-fe-value" title="concept-fe-value">value</a> on behalf of the user (e.g. as
  part of a form prefilling feature), the user agent must follow these
  steps:</p>

  <ol><li>If the <code title="event-input-input"><a href="#event-input-input">input</a></code> event
   applies, <a href="webappapis.html#queue-a-task">queue a task</a> to <a href="webappapis.html#fire-a-simple-event">fire a simple
   event</a> that bubbles named <code title="event-input">input</code> at the <code><a href="the-input-element.html#the-input-element">input</a></code>
   element.</li>

   <li>If the <code title="event-input-change"><a href="#event-input-change">change</a></code> event
   applies, <a href="webappapis.html#queue-a-task">queue a task</a> to <a href="webappapis.html#fire-a-simple-event">fire a simple
   event</a> that bubbles named <code title="event-change">change</code> at the <code><a href="the-input-element.html#the-input-element">input</a></code>
   element.</li>

  </ol><p class="note">In addition, when the <code title="event-input-change"><a href="#event-input-change">change</a></code> event applies, <code title="event-change">change</code> events can also be fired as part
  of the element's <a href="content-models.html#activation-behavior">activation behavior</a> and as part of the
  <a href="editing.html#unfocusing-steps">unfocusing steps</a>.</p>

  <p>The <a href="webappapis.html#task-source">task source</a> for these <a href="webappapis.html#concept-task" title="concept-task">tasks</a> is the <a href="webappapis.html#user-interaction-task-source">user interaction task

  parent element's <code title="">rows</code> collection (for tables,
  that's the <code title="dom-table-rows"><a href="the-table-element.html#dom-table-rows">HTMLTableElement.rows</a></code>

  collection). If there is no such parent element, then the attribute
  must return &#8722;1.</p>

  <p>The <dfn id="dom-tr-cells" title="dom-tr-cells"><code>cells</code></dfn> attribute

  <p>The <dfn id="dom-tr-insertcell" title="dom-tr-insertCell"><code>insertCell(<var title="">index</var>)</code></dfn> method must act as follows:</p>

  <p>If <var title="">index</var> is less than &#8722;1 or greater than the

  <p>If <var title="">index</var> is missing, equal to &#8722;1, or
  equal to the number of items in <code title="dom-tr-cells"><a href="#dom-tr-cells">cells</a></code> collection, the method must create
  a <code><a href="the-td-element.html#the-td-element">td</a></code> element, append it to the <code><a href="#the-tr-element">tr</a></code> element,
  and return the newly created <code><a href="the-td-element.html#the-td-element">td</a></code> element.</p>

  <p>Otherwise, the method must create a <code><a href="the-td-element.html#the-td-element">td</a></code> element,
  insert it as a child of the <code><a href="#the-tr-element">tr</a></code> element, immediately
  before the <var title="">index</var>th <code><a href="the-td-element.html#the-td-element">td</a></code> or
  <code><a href="the-th-element.html#the-th-element">th</a></code> element in the <code title="dom-tr-cells"><a href="#dom-tr-cells">cells</a></code> collection, and finally must
  return the newly created <code><a href="the-td-element.html#the-td-element">td</a></code> element.</p>

  <p>The <dfn id="dom-tr-deletecell" title="dom-tr-deleteCell"><code>deleteCell(<var title="">index</var>)</code></dfn> method must remove the <var title="">index</var>th element in the <code title="dom-tr-cells"><a href="#dom-tr-cells">cells</a></code> collection from its parent. If

  <hr><p>Data mining tools and other user agents that perform operations
  on content without running scripts, evaluating CSS or XPath
  expressions, or otherwise exposing the resulting DOM to arbitrary
  content, may "support namespaces" by just asserting that their DOM
  node analogues are in certain namespaces, without actually exposing
  the above strings.</p>

  <hr><p class="note">In <a href="syntax.html#syntax">the HTML syntax</a>, namespace prefixes
  and namespace declarations do not have the same effect as in XML.
  For instance, the colon has no special meaning in HTML element
  names.</p>
