Credits & Inspiration

Kitty Giraudel

A heartfelt thank you to @KittyGiraudel for creating a11y-dialog which inspired me to create a kindred-spirited and comparable a11y-tabs. Specifically, I found a11y-dialog's small surface API, clear documentation and sandbox demo made ramping up quite efficient. As such, I followed the same patterns with a11y-tabs.

WAI-ARIA & MDN

I was also inspired by the WAI-ARIA practices resources, and MDN tab role documentation efforts. Both resources certainly provided helpful and prescriptive guidance for this project.
