QR Code component with HTML/CSS

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

I actually completed this challenge a long time ago, but I didn't upload the solution. Looking back, I'm proud that I completed the challenge and going forward, I will upload my solutions when completing. I also would like to pay closer attention to the amount of CSS I write.

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

I would like feedback on accessibility, thank you!
