Congrats to editors @awkawk (@Adobe), @joshueoconnor (#InvitedExpert), @alastc (@we_are_nomensa) (who are also chairs of the @w3c_wai Accessibility Guidelines #WorkingGroup - w3.org/WAI/about/groups/agwg…), @cooper_w3c (@w3c) and all #WorkingGroup participants: kwz.me/htk

The initial work dates back from 1997 with the release of WCAG1.0 and its popular WAI quick tips to make accessible #websites. WCAG2.0 was published in December 2008 and later became an #ISO standard (#ISO40500) in 2012.

#WCAG21 is backward compatible with WCAG 2.0, and the three levels of success criteria (A, AA, AAA) still apply.

#WCAG21 provides 17 additional success criteria to address mobile accessibility, people with low vision, people with cognitive and learning disabilities. Read more: w3.org/WAI/standards-guideli…

The success criteria were tested in implementations across different types of #websites and Web content. Check out the #WCAG21 implementation report: w3.org/WAI/WCAG21/implementa…

#developers and #authors are invited to use #WCAG21 to make the #Web accessible to EVERYONE! w3.org/WAI/standards-guideli… #MaketheWebBetter #WebForAll
