Introduction to Techniques for WCAG 2.0

This Techniques for WCAG 2.0 document provides guidance for web content authors and evaluators on meeting Web Content Accessibility Guidelines (WCAG) 2.0 [WCAG20] success criteria. It is part of a series of documents published by the W3C Web Accessibility Initiative (WAI) to support WCAG 2.0. For an introduction to WCAG, supporting technical documents, and educational material, see Web Content Accessibility Guidelines (WCAG) Overview.

WCAG 2.0 itself is a stable document that does not change. This Techniques for WCAG 2.0 document is updated periodically, about once a year, to cover more current best practices and changes in technologies and tools.

Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques..

Note: W3C cautions against requiring W3C's sufficient techniques. The only thing that should be required is meeting the WCAG 2.0 success criteria. To learn more, see:

Techniques for WCAG 2.0 is not intended to be used as a stand-alone document.
