Mobile and desktop QR code using media query and CSS Flexbox

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

I'm proud i was able to finish it in a short amount of time, next time i will be taking a mobile-first approach!

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

i was having some trouble when doing the media query because I use width instead of max-width in body, after an easy fix my media query was working fine.
