  superscript and the <code><a href="#the-sub-and-sup-elements">sub</a></code> element <a href="rendering.html#represents">represents</a>
  a subscript.</p><p>These elements must be used only to mark up typographical
  conventions with specific meanings, not for typographical
  presentation for presentation's sake. For example, it would be
  inappropriate for the <code><a href="#the-sub-and-sup-elements">sub</a></code> and <code><a href="#the-sub-and-sup-elements">sup</a></code> elements
  to be used in the name of the LaTeX document preparation system. In
  general, authors should use these elements only if the
  <em>absence</em> of those elements would change the meaning of the
  content.</p><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">

  superscript and the <code><a href="#the-sub-and-sup-elements">sub</a></code> element <a href="rendering.html#represents">represents</a>
  a subscript.</p><p>These elements must be used only to mark up typographical
  conventions with specific meanings, not for typographical
  presentation for presentation's sake. For example, it would be
  inappropriate for the <code><a href="#the-sub-and-sup-elements">sub</a></code> and <code><a href="#the-sub-and-sup-elements">sup</a></code> elements
  to be used in the name of the LaTeX document preparation system. In
  general, authors should use these elements only if the
  <em>absence</em> of those elements would change the meaning of the
  content.</p><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">
