QR-code component

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

I have a decently solid understanding of html and css, I mainly use typescript and wanted to come back to pure CSS and get some practice in!

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

Regarding the height of the html img tag. Deciding whether to size directly in the html or css style sheet. I ended up sizing in the html after some research as it would make the most since if I had more resolutions to add and a picture tag.

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

I am fairly confident that my solution is sufficient, but I would like input on the html/css img sizing debate.
