QR Code entry project using Flexbox and SASS

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

This was the first thing I've made on my own not following a tutorial. It took a lot longer than I thought but I'm generally happy with it. It was also good practice with SASS. I'm most proud about remembering that there's a difference between and * when styling (yes, that was an issue).

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

The margins were consistently the biggest issue for me. A lot of it for quite a while was me forgetting to add a box-sizing element to my reset and putting all of the body styling in the * tag. Google University didn't help there.
