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

It takes me less and less time to research each time I work on something new, although am still a newbie, it shows am learning. Working towards understanding these concept without the need to search.. If that makes sense

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

Trying to set the container to the mid of the screen without margin. Had to research a bit to understand the value of height and width(min and max).

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

How else can I center the container on the screen? What else can improve the page?
