QR Code page with CSS and HTML

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

I'm new to this frontend development thing, so I'm proud that I was able to solve the problem with little online consultation.

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

No really challenging problems were encountered in this project, just some questions about syntax, so a brief search resolved them.

It became clear to me that I needed more practice! XD

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

I would like to know if the organization of the code was adequate.
