Hi

Thanks for creating and releasing this project!

About a year I ago I privately forked tota11y to form the basis of my Dissertation project. A few months ago I was able to publicly release my project as a WebExtension for Mozilla Firefox and release the code under the same MIT license.

https://github.com/Skeletonxf/totally-automated-a11y-scanner

My project changed focus slightly from tota11y as I was focusing more on automated testing and the WC3's WCAG guidelines rather than visualisation. Although the user interfaces and intended use cases are different, I was able to keep the same Plugin interface from /plugins/base.js intact.

This means plugins from the two projects can be shared with very minor changes needed.

I have written plugins/tests for the following and if possible would like to contribute them back to tota11y:

  • WCAG 1.4.4 Resize Text & WCAG 1.4.12 Text Spacing specifications for recommended maximum changes from user style sheets that websites should support (ie text doesn't get clipped if enlarged 200%)

  • WCAG 2.5.3 Label in name guideline for programmatically determined text and visible labels matching to support speech input users

  • Table markup problems

  • WCAG 1.4.2 autoplaying audio guidelines

  • Extensions to the Labels plugin to test progress and meter elements.

  • Extensions to the Image alt-text plugin to test video elements for captions and audio descriptions (WCAG 1.2.2 and WCAG 1.2.5 respectively)

  • Extension for the Image alt-text plugin to test for alt text on input elements of type image

In my Dissertation project I have included references to the WCAG guidelines for all plugins and tests, and more supporting information in each about page. The text for the plugins in tota11y are a lot more terse right now.

For this process should I be condensing down the supporting information in the plugins/tests I have written and pull requesting each plugin/test to this project one by one?

One additional concern is that the addition of 4+ plugins fills up the toolbar by quite a lot. This has not been a problem for me because my WebExtension uses a sidebar and the plugins in the toolbar scroll, but might pose a problem on small screens for tota11y.
