QR code component using HTML & CSS

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

Simply just proud that I went ahead and started this journey. Will be looking into doing more programming instead of watching tutorials all the time.

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

A few challenges I came across:

1. Centering an element in the middle of the screen. Overcame this by searching for flexbox tricks.

2. Using a custom font. Never actually looked into this surprisingly and there seem to be several ways of doing this. Read somewhere online that @font-face is the way to go.

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

All css values have been used with pixels. Would it be possible to use rem instead? From what I learned you preferably want to use em or rem. Using pixel values would only be useful for border width and other small elements.

Why is @font-face the way to go opposed to for example embedding it as a link in the html?

Curious about other possibilities of centering an element in the middle of the page.
