QR code component solution using HTML and CSS only

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

Maybe the thing I like is the use of bem which makes the code clean and neat. In the future, I will try a slightly more difficult challenge.

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

The problem I faced was a little confused to understand the instructions from the README.md file. Because my native language is not English.

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

I'm still new to using BEM. And I really appreciate the feedback regarding the use of BEM.
