a11y.css

This CSS file intends to warn developers about possible risks and mistakes that exist in HTML code. It can also be used to roughly evaluate a site's quality by simply including it as an external stylesheet. When activating the stylesheet, a tip should appear beside each incriminated elements, displaying what’s going on. This file is not a replacement to a complete tool such as aXe, Tanaguru or Tenon. It only intends to show possible weaknesses. You should obviously do some manual check by hand to know whether the code should or should not be fixed. You can also use the form on the left sidebar to define the minimum level and language, in order to generate a custom bookmarklet. Then simply drag the green button to your bookmarks, and you're done! You're now able to use a11y.css on every page you visit by simply clicking on this bookmark.
