Mobile-first responsive menu using HTML & CSS

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

I tried to remember as much of the syntax as possible, before having to refer to MDN or other resources.

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

I had trouble articulating my issues, so it took me several Google searches to get to the right solution for me.

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

I'd like more help in consolidating my CSS classes. I feel like all of my classes are broken out when some could probably be combined.
