Web Content Accessibility Guidelines 2.0 (WCAG 2.0) covers a wide range of issues and recommendations for making Web content more accessible. This document contains principles, guidelines, success criteria, benefits, and examples that define and explain the requirements for making Web-based information and applications accessible. "Accessible" means usable to a wide range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning difficulties, cognitive limitations, limited movement, speech difficulties, and others. Following these guidelines will also make your Web content more accessible to the vast majority of users, including older users. It will also enable people to access Web content using many different devices - including a wide variety of assistive technologies.

WCAG 2.0 success criteria are written as testable statements that are not technology-specific. Guidance about satisfying the success criteria in specific technologies as well as general information about interpreting the success criteria are provided in separate documents. An Overview of Web Content Accessibility Guidelines (WCAG) 2.0 Last Call Documents is also available.

Until WCAG 2.0 advances to W3C Recommendation, the current and referenceable document is Web Content Accessibility Guidelines 1.0 (WCAG 1.0), published as a W3C Recommendation May 1999.
