WCAG 2.0 is Finalized: W3C Web Standard Defines Accessibility for Next Generation Web

On 11 December 2008 W3C announced a new standard that will help Web designers and developers create sites that better meet the needs of users with disabilities and older users. Drawing on extensive experience and community feedback, Web Content Accessibility Guidelines (WCAG) 2.0 improves upon W3C's groundbreaking initial standard for accessible Web content, applies to more advanced technologies, and is more precisely testable.

Want to know how people with disabilities use your Web site? Ask.

Web accessibility guidelines, techniques, and tools provide the basis for Web accessibility. Including people with disabilities in the Web development process helps to understand the "why" behind accessibility. It leads to more effective accessibility solutions, developed more efficiently. See "Involving Users in Web Accessibility Evaluation".   (2005-11-02)

Blogs, Wikis, CMS... Got ATAG?

Web content is created by many different types of tools these days: Web log (blog) comment features, Wikis for editing Web pages, content management systems (CMS), e-mail archivers, word processors, and more.

All of these tool are covered by WAI's Authoring Tool Accessibility Guidelines (ATAG), which explain:

Does your tool know ATAG?    (2005-07-22)

Web Accessibility: The Fellowship of the Guidelines

Many people know about WAI's Web Content Accessibility Guidelines (WCAG) and the responsibilities of Web developers in making the Web accessible to people with disabilities. But Web developers alone cannot make the Web accessible.

Web browsers, assistive technologies, and authoring tools also have a vital role in Web accessibility. Essential Components of Web Accessibility describes these roles along with the WAI guidelines.    (2005-07-22)
