Accessibility Checker

Accessibility Checker is an innovative solution that lets you inspect the accessibility level of content created in CKEditor and immediately solve any accessibility issues that are found.

It is built upon three key elements:

  • User Interface optimized for quick problem solving.
  • Flexibility allowing you to use the accessibility checking engine of your choice.
  • Quick Fix feature letting you fix common problems fully automatically!

The default implementation uses Quail as its accessibility tests library, but you can integrate any other similar library to achieve comparable results.


  • CKEditor 4.3+.
  • Balloon Panel plugin.
  • jQuery 1.x or later to run Quail.
