Responsive QR Code component using custom CSS

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

I'm proud that I was able to finish the project using my knowledge of html and css.

Next time, I'll learn sass and improve the solution using sass.

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

The most challenge is mainly centering the section and the responsive part.

I re-read the css and change little by little to see the change.

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

In the css, I would like to know if there is a way to shorten it,
