  • W3C Invites Implementations of Core Accessibility API Mappings 1.2

    <p>The <a href="https://www.w3.org/WAI/ARIA/">Accessible Rich Internet Applications Working Group</a> invites implementations of the Candidate Recommendation Snapshot of <a href="https://www.w3.org/TR/2022/CR-core-aam-1.2-20221122/">Core Accessibility API Mappings 1.2</a>.

  • Last Call for Review of Proposed Corrections: CSS Containment Module Level 1

    <p>The <a href="https://www.w3.org/groups/wg/css">CSS Working Group</a> has proposed corrections to the W3C Recommendation of <a href="https://www.w3.org/TR/2022/REC-css-contain-1-20221025/">CSS Containment Module Level 1</a>. This CSS module describes the <a href="https://www.w3.org/TR/2022/REC-css-contain-1-20221025/#propdef-contain">contain</a> property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.</p> <p>Proposed corrections are marked in the document. Comments, including implementation experience, are welcome via <a href="https://github.com/w3c/csswg-drafts/issues">GitHub</a> through <strong>10 January 2023</strong>.</p>
