FAQ Accordion project using JS

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

I'm starting to learn Javascript and this project, being the first that I do in a while, helped me a lot to think about the logic, do QA and investigate to know how to do it. It was simple but useful.

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

I haven't code in a while in JS, so my first problem was a basic one, the "defer" attribute, I solved it. Then I had normal and expectable difficulties thinking about how to create the functionalities. I investigate, create my own logic (Step by step what I wanted) and use the tools that I know and discover new ones to create it.

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

I didn't really focus on the background, I just use 2 colors and that's it. How the fancy lines are supposed to be done? What of my solution can I improve? Thanks
