Guideline 3. Use markup and style sheets and do so properly.

Checkpoint 3.4 - Use relative rather than absolute units in markup language attribute values and style sheet property values

How do I do it?

Use percentages or ems rather than pixels (see line-height below) and use relative font sizes such as small or large (see font-size below).

 p{

        font-family: 
        Verdana, Arial, Helvetica, sans-serif;

        line-height: 
        150%;

        color: 
        #666666;

        font-size: 
        small;

        }

How do I check that it meets the WCAG criteria?

WebXact claims to validate this checkpoint, however I believe it only checks the HTML and not the CSS stylesheet. To check your HTML, run your page through webXact's accessibility checker.
