aria-actions

A proposed ARIA attribute that lets an element — such as a composite-widget item or message card — reference related action buttons (for example, a tab's close button) so accessibility APIs can expose those actions without folding them into the host's accessible name. The ARIA change is proposed in the open, unmerged w3c/aria PR #1805, not current normative ARIA text. Chrome's implementation is recorded as Enabled by default on Windows/Mac/Linux desktop in Chrome 151 (v151 milestone listing; the feature detail still says In development, updated 2026-07-01; not yet on ChromeOS or Android). The demos separate author markup, DOM reflection, accessibility-platform mapping, and assistive-technology behavior rather than claiming that a headless page verifies all four.

concepts

  1. Action Card Grid

    A grid of cards, each with a primary label and secondary action buttons (edit, delete, share) linked via aria-actions. Click the actions, and probe what the browser actually reflects at the DOM level.

  2. Tree View Actions

    A file-tree widget with arrow-key focus navigation and secondary actions (rename, move, delete) on each node. aria-actions connects them — with an honest probe of this browser's DOM support rather than assumed accessibility-platform or AT exposure.
