What is "wcag"
Summary
The Web Content Accessibility Guidelines (WCAG) 2.0 cover a wide range of recommendations that aim to make web content more accessible. Compliance with these guidelines will make content accessible to a greater number of people with disabilities, including blindness and low vision, deafness and low hearing, learning difficulties, cognitive limitations, movement limitations, speech disability, photosensitivity as well as those that have a combination of these limitations. Following these guidelines will also make web content more usable to users in general.
The success criteria of WCAG 2.0 are written in the form of testable statements, which do not depend on a specific technology. Guidance on how to meet a specific success criterion for a particular technology, as well as general information on the interpretation of a particular success criterion, are available in separate documents. Consult the document An Overview of Web Content Accessibility Guidelines (in English) for background information and access to a set of links for WCAG technical and didactic documentation.
The WCAG 2.0 succeeds the Web Content Accessibility Guidelines 1.0 (in English) [WCAG10] published as a W3C Recommendation in May 1999. While content may comply with WCAG 1.0 or WCAG 2.0 (or both), the W3C recommends that new or updated content use WCAG 2.0. W3C also recommends that web accessibility policies refer to WCAG 2.0.
