    [Show Introduction]

    This document lists all of the requirements (called "success criteria") from Web Content Accessibility Guidelines (WCAG) 2.0. It also lists techniques to meet the requirements, which link to more details. The "Understanding" links go to descriptions, examples, and resources.

    You can customize the list by selecting the technologies that apply to your Web project, and the levels and techniques that you want included in the list.

    Technology-specific techniques do not supplant the general techniques: content developers should consider both general techniques and technology-specific techniques as they work toward conformance.

    Note: In some customized views, no techniques will be listed under some headings. This indicates that there are no documented techniques for the technologies chosen.

    See the WCAG Overview for an introduction to WCAG and supporting documents, including more information about this document.

    About the Techniques

    Note that all techniques are informative - you don't have to follow them. The "sufficient techniques" listed below are considered sufficient to meet the success criteria; however, it is not necessary to use these particular techniques. Anyone can submit new techniques at any time. If techniques are used other than those listed by the Working Group, then some other method for establishing the technique's ability to meet the success criteria would be needed.

    In addition to the 'sufficient techniques', there are also advisory techniques that go beyond WCAG 2.0's requirements. Authors are encouraged to apply all techniques that they are able to, including the advisory techniques, in order to best address the needs of the widest possible range of users.

    Note that even content that conforms at the highest level (AAA) will not be accessible to individuals with all types, degrees, or combinations of disability, particularly in the cognitive language and learning areas. Authors are encouraged to seek relevant advice about current best practice to ensure that Web content is accessible, as far as possible, to this community.
