Responsive QR Card Component

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

I think this was a fairly basic one but it feels nice to be able to know the bare minimum that I do and replicate it

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

I still struggle with aspects of width and height / length, it's hard to understand what takes up what space

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

Is my project responsive? Does it match the mobile layout?

I would also like assistance in the height x width/length topic
