Responsive Card With QR Code

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

I'm proud of making card responsive only using true units of measurement like vh. And I would like to do more useful css element layers.

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

That was easy for me. But I had little problems with text wrapping.

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

I want help about units of meausurement. Especially I want to know more about responsive sizing.
