QR code component challenge - HTML/CSS & Flexbox

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

I'm not particularly proud of my work on this project, but the result is quite close I think.

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

I tried several times to get the paddings for the text that it was be the same as the design. I had to go over it again and again, even though I could see which ones to work on.

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

1. Is the CSS properly organized?
2. And have I correctly broken down my HTML code (div, class, ...)?
3. Thank you!
