React.js Intro section with dropdown navigation solution

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

What I was proud of was being able to create a dropdown menu from scratch, and being able to style it to my liking as well as conforming it to the required style of the challenge.

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

Being able to correctly lock in place the navigation elements when it came to opening the menu on a mobile viewport.
