QR Code Component with HTML5 & CSS3

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

I'm most proud of getting my project deployed successfully and ensuring that it looks good on different screen sizes. I noticed that my approach to responsiveness differs from some other implementations, and I'd like to experiment more with different techniques to achieve smoother scaling. Additionally, I'll focus on refining my CSS structure to make it more maintainable.

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

As a beginner, my biggest challenge was turning scattered knowledge into a functional project. Without experience in the full process, I studied how others approached similar tasks and combined their insights with what I had learned. This helped me gradually piece everything together and improve my problem-solving skills.

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

Currently, I’ve used px for sizing, but I’ve seen other approaches using rem. Should I switch to rem/vw for better responsiveness, or is using px still acceptable? I’d love some feedback on how to improve my approach!
