The font-size rule sets the size of the fonts in the element. You can express the size using an absolute measurement or a relative measurement. For example, the following rule (in a STYLE tag or in a style sheet file) sets the font size of
<H2 ...>80 points:
H2 {font-size:80pt}
which gives us this <H2 ...>
Relative font sizes allow you to specify font size relative to the surrounding text. For example, this rule sets the font of
<EM>180% the size of the surrounding text, making
<EM>
EM {font-size:180%}
So this string that uses <EM>
That is a <EM>groovy</EM> idea!
looks like this:
That is a groovy idea!
Using relative font sizes when applied to headers has a special problem that is worth understanding. We'll discuss that in the next page.
