QR code component using HTML and CSS

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

I thought this was a simple, straightforward project, ideal for beginners. If I had to do things differently, I would try to organize my CSS better.

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

The challenge was making sure it was responsive. I was able to achieve this by making the width of the card a percentage and by using rem units.

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

I'd appreciate any feedback on how I could improve and advice on using best practices.
