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

Always proud to complete a challenge. If I had it any other way, I wouldn't do anything different. 1 year ago I had already completed this challenge without ever submitting it. In the meantime, I've moved on, and now that I'm back on Frontendmentor.io with the firm intention of completing every challenge, I realize that I'm moving in the right direction. The difference in code between what I'm delivering today, having reset the challenge from scratch, and the solution I'd coded a year earlier, which will remain well guarded, leads me to believe that I was right to take this break and come back even stronger.

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

This isn't really a problem, but being able to change the style of the HTML details element has been made much easier thanks to a perfect resource for this (link on the README.md of my repository).

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

Nothing in particular is always open to constructive criticism.
