Abstract

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.

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. For important information about techniques, please see the Understanding Techniques for WCAG Success Criteria section of Understanding WCAG 2.0.

Techniques for WCAG 2.0 is not intended to be used as a stand-alone document. Instead, it is expected that content authors will usually use How to Meet WCAG 2.0: A customizable quick reference to read the WCAG success criteria, and follow links from there to specific topics in Understanding WCAG 2.0 and to specific techniques.

This is a Working Group Note "Techniques for WCAG 2.0". These techniques are produced by the Web Content Accessibility Guidelines Working Group to provide guidance about how to conform to the Web Content Accessibility Guidelines (WCAG) 2.0 Recommendation. Techniques are referenced from Understanding WCAG 2.0 and How to Meet WCAG 2.0. Please note that the contents of this document are informative (they provide guidance), and not normative (they do not set requirements for conforming to WCAG 2.0).

WCAG 2.0 Techniques was previously published on 11 December 2008 as a Working Group Note and updated 14 October 2010, 3 January 2012, 5 September 2013, 3 March 2014, 8 April 2014, 16 September 2014, 26 February 2015, and 17 March 2016. This new version updates the support information provided for WCAG 2.0. Note that WCAG 2.0 itself remains unchanged, only the informative support materials have been updated. Primary changes include clarifications based on input from the public and translators. Changes in this version include clarifications in techniques G136: Providing a link at the beginning of a nonconforming Web page that points to a conforming alternate version, ARIA2: Identifying a required field with the aria-required property (ARIA) , and F68: Failure of Success Criterion 4.1.2 due to a user interface control not having a programmatically determined name .

The changes are highlighted in the diff-marked version.
