I’ve built a good handfull of accessible markup patterns and widgts at this point. Each is based on testing with users, UX and design needs of past projects, and from following W3C specifications & notes. I do enjoy making these :)
This is an on-going project, so expect to see more scripts (and non-JS markup & CSS patterns) as time permits.
If you end up using any of these components, please let me know!
Most importantly, if you ever come across a bug or awkward UX quirk with a component listed here, please file an issue in the that component’s GitHub repository.
