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

That was my very first HTML/CSS project. I did complete and it looks like the example, but it's not in the same size and may lack of semantics.

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

I guess, understanding the tags and making the divs was my first challenge. Then, position it accordingly in the CSS was my second challenge.

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

Definetly JS, i know nothing about it.
