拡張機能の使用方法

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
