I've used css flexbox, im without practice, so its the best i could.

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

im not proud of it, im just practicing.

in the next time i will do the "mobile first" thing.

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

didnt have like a "challenge", im just without practice...

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

the mobile first thing and how to change the heights without crashing the flexbox.
