Technique C13:Using named font sizes

Applicability

CSS

This technique is not referenced from any Understanding document.

Description

The objective of this technique is to specify a named font size that expresses the relative font size desired. These values provide hints so that the user agent can choose a font-size relative to the inherited font-size.

Examples

Example 1: Named font sizes in CSS

This example selects a larger font size for strong elements so that their text will always be larger than the surrounding text, in whatever context they are used. Assuming that headings and paragraphs use different font sizes, the emphasized words in this example will each be larger than their surrounding text. 

<style>
  strong {font-size: larger}
</style>
...
<h1>Letting the <strong>user</strong> control text size</h1>
<p>Since only the user can know what size text works for them, 
 it is <strong>very</strong> important to let them configure the text size.
