QR Code Page with CSS

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

I have forgotten after not studying for a while, but after some time I understand what to do and which part to manipulate. Then I have revised the code but sometimes I had to ask to ChatGPT which is I am not proud of. I will try to check less ChatGPT and check the Internet more by manually in the next time.

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

I didnt understand this display:flex display: float etc. when learning for the first time and still dont understand fully, that is why I used ChatGPT at some point.

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

Did I use divs correctly? Did I use CSS codes next to the body directly correctly? Should I have used these CSS codes by opening style?
