Guideline 3. Use markup and style sheets and do so properly.
Checkpoint 3.3 - Use style sheets to control layout and presentation
Style sheets are promoted as they can be turned off by the user using the accessibility options available in many browsers, as follows:
- Internet Explorer: Tools > Internet Options > Accessibility options
- Netscape: View > Page Style > No Style
- Firefox: View > Page Style > No Style
This can be useful for some dyslexic individuals who find it easier to read using various colour schemes, and for colour blind individuals who may find it difficult to see page elements using the given colours.
How do I do it?
Use en embedded or external style sheet to control your page layout and presentation. Many css tutorial web sites are available to help you learn this skill.
How do I check that it meets the WCAG criteria?
This check is purely to ascertain whether style sheets were used, not whether they are grammatically correct. Pages which have neither a linked or embedded style sheet (as verified by testing in guideline 3.2) will fail the check. Sites using frames should have a style sheet on or linked from each framed page.
