FAQ accordion - CSS only, semantic HTML, and keyboard accessibility

What are you most proud of, and what would you do differently next time?

This one was a ton of fun. After looking around a bit about how to implement a CSS only accordion, I finally stumbled across the element, which was perfect for the job. Semantically appropriate, accessible, and easy to implement.

What specific areas of your project would you like help with?

I am a little confused about why I'm getting some HTML validator errors by using the name attribute in the details elements. Can anyone help me figure out what I did wrong? Seems to me like I am using the name attribute in the appropriate way. But maybe I am missing something? 🤔
