Tip Calculator with Semantic HTML, Flexbox, Javascript

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

The responsiveness, while not 100% perfect, came out pretty good I feel.

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

Took me a bit to work through the logic of calculating the totals without affecting other inputs. I made sure to organize my js and keep functions separate so event listeners didn't get to cluttered.

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

any and all feedback welcome. If there is ways I can refactor or cut down code and combine things, will still maintaining readability, I am open to suggestions!
