Web Components Accessibility FAQ
When I first learned about web components, I had a lot of questions, especially regarding accessibility. While I found answers to many of them, I didn’t know everything I would’ve wanted to know. I wish I had a catalog of all the essential questions and answers when I started. That’s why I decided to design this post in a Q&A format. I’ll ask a question regarding the accessibility of web components, and then I’ll answer it.
