The Accessibility module can check both content and themes for accessibility, and can check content while viewing or editing with a supported WYSIWYG editor. Below are demonstrations of the module at work:

  • Viewing content - The user is viewing content where the body field has accessibility checking turned on. Note that we enabled access to this for anonymous users, in the real world you probably want to tweak this to only be shown to authors.
  • Editing content - A demonstration form using CKEditor 4. Click the checkbox icon (the first in the editor toolbar) to highlight accessibility problems in the page.
