JavaScript Bookmarklets for Accessibility Testing


A “bookmarklet” is a piece of JavaScript that can be saved as a bookmark in your web browser. The bookmarklets in this post help web developers and designers see the “big picture” regarding web accessibility.

The bookmarklets do this by:

  • Making otherwise hidden accessibility features on web pages (like ARIA landmarks, roles, labels and descriptions and alternative text for non-text objects) more visible
  • Showing whether HTML markup (like lists, headings, label elements, and appropriate landmark roles) is used with proper semantics for accessibility
  • Flagging elements or regions on web pages where information that could improve accessibility (like elements not contained in landmarks, image alt text or long descriptions, list accessible names or descriptions, or form control labels) is missing
