QR Code using basic HTML & CSS

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

Kept it simple with basic HTML and CSS. I'd probably try using viewport units next time for better responsiveness if I did this again.

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

I didn't quite figure out the text break on the third line. Mine is 4 words long, the example is only three. I also had a really hard time figuring out GitHub. I've never worked with it before. Hopefully it displays correctly.

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

Could I have simplified the code any further? Is there anything redundant or otherwise unnecessarily declared that could have saved me time and the overall amount of code?
