"If the property is specified for a block-level element, it affects all
inline-level descendants of the element. If it is specified for (or
affects) an inline-level element, it affects all boxes generated by the

In the case of a block-level element, all inline-level descendants are
affected. Nothing about the element's box itself, whereas for
inline-level elements, it affects _all_ boxes generated by the element,
explicitly including the element's box.

Is the block-level element's box then implicitly affected?

How does text-decoration affect a _block_ box?

<DIV style="text-decoration: underline">
<P> Some Text <SPAN>spanned text</SPAN> </P>

So, would the "spanned text" be underlined, even though "Some Text", as
you say, would not?

<DIV style="text-decoration: underline">
<P> And all of a sudden, the underline <em>*appeared*</em>! </P>

The spec also says that text-decoration is not inherited. If it is to be
inherited, the spec should say that text-decoration is inherited and
that the color is inherited with it, no?

Are you saying that the user agent determines a fixed position relative
to the baseline for all underlining, regardless of what font is used for
the underlined text?

Supposing I have a page demonstrating ancient Egyptian hieroglyphs. If I
represent these glyphs as Unicode text, how is anyone to see them? They
do not have a font with these glyphs on their system.

I ask the viewers to download such a font, the only one I have on hand.

But the font is seven megabytes because it is a general unicode font
including the Latin, Arabic, Cyrillic, Hangul, Hiragana, Katakana, and
CJK Ideograph sets, among others.

Nobody wants to download seven megabytes of font just to view a single

Therefore, in the name of semantics, I must learn to create my own font?
