QR Code using flex model

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

Was able to come up with an idea to link my github page to the qrcode.

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

Was confused on how to center the card in the display. I tried to position it and failed, later realised flex makes it easier.

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

Need help in reducing the amount of css code i am using. I am not sure if all are really useful. I am always checking twice for unwanted piece of code.
