First JS project/ accordion

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

Well, that's my first project with JavaScript, I'm happy that I make this work and that's also good opportunity to write some code by my self, because I'm taking JS course right now. I know my code is not clean but my goal is to make this work.

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

I do not know how to make the border dissapear after clicking the button. I create the class in css and just toogle It after clicking button.

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

Any feedback is good. As I said that was my first JS code so I know there's a lot of misstakes
