Responsive QR code landing page using HTML and CSS

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

Firstly, I am most proud of my ability to pull it off. Lol, thinking about where I started a few weeks ago with zero knowledge of anything concerning frontend development, I must say that I am proud of myself.

Secondly, I would try the mobile first approach next time and wouldn't beat myself up too hard when I can't seem to get something working.

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

I encountered a challenge of moving the QR code component to the center of the screen for the mobile viewport, but I overcame it when I referred back to previous tutorials I had taken on the flexbox technique I used.

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

Basically, just making the codes a bit shorter and more pro-like, if that makes sense, lol.
