QR Code Challenge Using CSS Flexbox

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

I was able to make the QR Code look as close to the design as possible.

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

There were problems with padding on smaller screen sizes. I used a media query to resolve that issue.

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

Does the structure I provided for my code make sense? Additionally, I used rem instead of px for all font sizes and line spacing, but used px for padding, border radius, width, etc. Is that correct?
