Overview
Product summary
Review the store description, core capabilities, and common use cases.
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

Great, except with the extension you have to toggle it a few times depending on what state you last left it in or you won't see anything.
This is a great effort and it tackles a good amount of details that are commonly missed but it doesn't (from our testing) account for color contrast issues and other commonly found issues when doing audits.
Didn't work
