responsive qr-code-challenge with html and css flex-box

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

This one was my first one, I very good one to start to get some practice, I really enjoyed it! Next time I'll try to write less and get a good result.

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

The main challenge for me was to centralize everything. To overcome I learned about flexbox and put on my code.
