Accessibility and Contrast Bookmarklet

This is a bookmarklet to run on any page to analyse the contrast of the text on a page and highlight elements which may have readability issues.

This project was grew out of a piece of work I did for general page analysis but I thought this component was interesting enough to explore as a standalone tool as it doesn’t need to use any 3rd party service to perform the analysis.

The project page is hosted on GitHub pages: Contrast Widget.
