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

I am proud of completing first challenge only by using my own knowledge.

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

There a some challenges regarding size of the component. I still find it hard to decide which size to use. Normally, as in this project, I would use max-width for the components. But I am still sure if this is the best option.

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

Centering the component. I still have no clear picture of what is the best way to center a component.
