QR code component

Thank you for reviewing my project! This time, I tried to write a cleaner, more understandable code which will be hopefully more maintainable. I also used more semantic html elements than in my last projects.

I have been struggling with the positioning of the main wrapper element. I'd like to hear what your approaches are in terms of centering it. I noticed that all my solutions are quite a bit off.

Please let me know, if you have any suggestions on how to improve.

Cheers
