Vanilla HTML CSS, if someone can check if semantic looks good or not ?

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

It been a while since I have practiced and I'm back at it !

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

Not much to be honest cause I've used a lot MDN.

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

I want to be sure about semantic, if there is something to do better, any advices are welcome.
