HTML5 Accessibility

About HTML5 Accessibility

HTML5 Accessibility is a testing site that tracks the accessibility support status of newer HTML5 features across major browsers. It reports whether each feature is keyboard accessible, mapped to platform accessibility APIs, and whether related accessibility features are supported, covering elements such as article, section, nav, aside, header, footer, figure, main, time, mark, canvas, audio, video, track, form input types (search, tel, url, email, date, number, range, color, and others), datalist, output, progress, meter, details/summary, and dialog.

The site presents an overview of accessibility support percentages for specific browser versions (including Chrome, Edge, Firefox, Internet Explorer, and Safari on Windows and Mac OS), along with detailed per-feature tables breaking down implementation status, API mapping, name/description support, keyboard support, and error-state mapping. It also links to a blog and to further resources on how to interpret the test results.

It is intended for web developers and accessibility practitioners who need to know which HTML5 elements and input types can be used without requiring supplemental ARIA or other workarounds to remain accessible in a given browser.
