Working QR-Code using HTML and CSS

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

I'm proud of how the design looks overall. I think I would adjust the div settings to make a smaller size and to experiment with the image size.

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

I had an issue with placing the image properly and I put it inside of the div which made sizing the image a bit easier since I didn't have to worry too much about it being significantly affected every time I would change the size of the div.
