Using CSS Grid and FlexBox

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

My very first solution ladies and gentlemen. I hope I continue the same and solve more and more.

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

Overflow challenges and I learned how to prevent them.

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

I think I have dirty css and I would love you guys to give me some shortcuts that you as professionals use. On the other hand, if you don't mind tell whether I have used appropriate HTML tages or not.
