Accordion using HTML+CSS+JS

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

I'm proud to have successfully built a page with a 100% accessibility score according to the Lighthouse test. What I would do differently is render the accordion items using a list's map function, instead of writing the HTML four times in the code.

What challenges did you encounter, and how did you overcome them?

The biggest challenge was creating the animation to hide the accordion items. For that, I used JavaScript.

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

I'd like to know if I should have used the <ul> component, with <li role='button'>, instead of buttons for the accordion headers. I was unsure which alternative is more correct.
