Accordion using nextElementSibling and classList.toggle

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

I'm starting to learn how to work with nextElementSibling, and I think it is a very useful tool for this kind of code.

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

I need more practice making animations in CSS. I was stuck on the height animation until I found that 'height' is not animable but 'max-height' is.
