Faq accordions with animation! (First Js challenge🎉🚀🎊).

My first Js challenge here!🚀🎊 Let me know what you think. What I found difficult here was implementing a logic that closes one when another one open but it doesn't work out. Another thing I found difficult was html and css and also how to structure and plan them, I've left them for a while now to learn js and they came back to hunt me.
