Responsive website with max-width using flexbox

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

Nice project all around. HTML was done pretty quick and I am getting familiar with FlexBox. CSS still took most of the time. I tried using % for responsiveness but it messed up my layout on desktop. I guess it was not the goal of this challenge

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

Still having some little issues with FlexBox align-items and justify-content with row and column display.

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

I feel like I called out 'display:flex;' too many times. Can you have a look ?
