A Simple QR Code Project using only HTML and CSS

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

I am proud because I have successfully completed a project of a renowned website. I want to learn further about frontend development from this website.

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

I am basically very weak in responsive web designs. So I encountered a challenge for making this project responsive. But I overcame them with very simple codes.

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

I would like to know about placing an object to the center of a website. I think there is a better way to place the QR code in the center.

If you know, please tell me.
