These are links to articles I've run across in various ways (initially, from channels in the a11y slack group). I'm saving them here to access them from anywhere and maybe others will find this list useful.
I could fill this list with dozens of articles from blogs of people I've already mentioned in accessibility resources. That might be overwhelming, too much to keep updating, and mostly duplicate their blog listings. Though realistically, I might add links here and later realize the author is a prolific accessibility blogger and add their blog link to the resources page. So don't be shocked to find links to blogs here that could easily be found by searching a bloggers list of articles.
- Accessibility APIs - Get deep into how accessibility works at the programming level. There are 3 parts to this post, follow the links in each part to go to the next one.
- What exactly is the accessibility API? - Pairs well with the Accessibility APIs article from Knowbility.
- Web Components Accessibility FAQ - Great article about Web Components and accessibility.
- These (still) aren't the SCs you're looking for - Great presentation by Patrick H. Lauke regarding pitfalls people run across while trying to determine correct Selection Criteria (SC) while performing accessibility audits.
