The World Wide Web Consortium (W3C) yesterday issued Web Content Accessibility Guidelines (WCAG) 2.1 as a Recommendation. WCAG 2.1 includes all the guidelines from WCAG 2.0, and adds 17 new criteria. Many of the new guidelines deal with accessibility on mobile devices, a topic which is not specifically addressed in WCAG 2.0. WCAG 2.1 also includes new guidelines addressing cognitive and learning disabilities, and low vision.
The W3C stated in their press release on the topic:
“WCAG 2.1 updates WCAG 2.0 and expands W3C’s accessibility guidance, while maintaining W3C’s standard of implementable, technology neutral, objectively testable and universally applicable accessibility guidance. All new provisions have been tested in implementations across different types of websites and web content. The Working Group has taken care to maintain backwards compatibility with the internationally-recognized WCAG 2.0, in that websites that conform to WCAG 2.1 will also conform to WCAG 2.0, which remains a W3C Recommendation.”
