Qr Code using css variables

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

I'm proud that I was able center it both directions, and what I would like to do differently next time is to adjust the size since I ended up making it a little bit bigger on the layout.

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

I was really struggling centering layouts and finally, I found out that you need to put a height first before you can center with flex, just a personal experience though and I'm sure there's lots of better way to do this.

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

I think it would be screen dimensions, wanting to know more about the best practices for it on all screen sizes, and advanced techniques for centering like other methods and RWD tips.
