This document provides information to Web content developers who wish to satisfy the success criteria of "Web Content Accessibility Guidelines 2.0" [WCAG20] (currently a W3C Working Draft). The techniques in this document can be applied to a wide range of Web technologies. Use of the illustrative techniques provided in this document may make it more likely for Web content to demonstrate conformance to WCAG 2.0 success criteria (by passing the relevant tests in the WCAG 2.0 test suite - to be developed) than if these illustrative techniques are not used.

There may be other techniques besides those provided in this document that may be used to demonstrate conformance to WCAG 2.0; in that case, it is encouraged to submit those techniques to the WCAG WG for consideration for inclusion in this document, so that the set of techniques maintained by the WCAG WG is as comprehensive as possible. Deprecated examples illustrate techniques that the Working Group no longer recommends, but may be applicable in some cases.

Note: WCAG 2.0 is a Working Draft and the cross-references between success criteria and techniques are not fully established.

This document is part of a series of documents published by the W3C Web Accessibility Initiative (WAI) to support WCAG 2.0.

Editorial Note: As work on the technology-specific techniques documents and checklists progresses, we expect to clearly distinguish between techniques required for conformance versus those that are optional. That distinction is not made in this Working Draft. The issue is captured as Issue #772 -"How do we make it clear that there are some techniques that are sufficient and some that are optional?"

This document is prepared by the Web Content Accessibility Guidelines Working Group (WCAG WG) to show the way a General Document for Techniques for WCAG 2.0 might read. This draft is not yet based on consensus of the WCAG Working Group nor has it gone through W3C process.

The primary purpose of this document is to show how success criteria and general techniques map to HTML and CSS Techniques. Only Guidelines 1.1 and 1.3 are covered in this draft. In the future, the rest of the guidelines will be incorporated as well as other technologies such as SVG and SMIL. Please refer to "General Techniques Issues" for a list of open issues related to this Working Draft. The WCAG WG intends to publish this as a Working Group Note at the same time or soon after WCAG 2.0 becomes a W3C Recommendation.
