QR Component using Sass

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

This is my first project where I delve deeper into CSS3 and HTML5, experimenting with these technologies. I finally completed the challenge, but creating this simple page took a long time. I hope to become faster at this in the future.

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

My initial approach involved trying to position elements using 'margin: auto', but I then switched to using flexbox, which made things much easier.

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

Though this is my first deeper dive into the world of CSS3 and HTML5, I may encounter some pitfalls that I'm not yet aware of. I would really appreciate it if someone could review my CSS styling. Criticism is welcome!:)
