QR code component using CSS variables

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

I'm proud of how close to the design I could get my implementation. Next time I will start with a CSS reset.

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

I had issues with spacing due to not having box-sizing: border-box; universally. I also initially had trouble centering the card vertically because my page wasn't taking up the entire space available. I fixed that by setting the html and body's height to be 100vh.

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

On better code quality including better semantic HTML usage and what I could have done more efficiently in my CSS.
