Responsive QR code component

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

I've been proud of myself after the challenge because I'm learning how to create a website from a design and make it responsive to mobile.

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

My challenges that I've encountered so far is how I center elements within the page. I overcome it by learning flexbox and grid. My other challenge is how can I change my style on a mobile to make the website responsive. I overcome it by using media queries.

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

Please let me know how I can improve my work in this challenge. Thank you
