WCAG 2.2 Quick Reference
A single page reference covering all WCAG 2.0/2.1/2.2 success criteria.
I used the PHP library: simple_html_dom and created a script. Whilst WCAG 2.2 was being developed, this script queried nightly the WCAG 2.2 Editors Draft and the WCAG 2.2 quick ref guide to get all success criteria, associated techniques and failures listings for each success criteria. All of this is piped into a MySQL database, then displayed on my handy reference site.
Now WCAG 2.2 is published, this same script runs weekly, and just queries for updated sufficient techniques, advisory techniques, and failures.
The site is built progressively with PHP outputting valid HTML, CSS with plain JavaScript
