About this extension
First a11y.css was a bookmarklet inserting a stylesheet into the page.

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.

This extension does the same, plus adds some tools:
  • Outline focus (keyboard navigation)
  • Show languages used (relies on lang attributes)
  • Check alt and title attributes on images

You can submit your bugs on github.

Original bookmarklet code: Gaël Poupard
Extension code: Stéphane Deschamps
Thanks to Anthony Ricaud and Mathieu Pillard for their help!
