I found this article to be very helpful on centering: https://css-tricks.com/centering-css-complete-guide/ For my solution, I followed the guideline under centering vertically & horizontally, with the element of being a fixed width and height.
I'd extend the width of your qr component card so that the text flows better. I do like how the color of the footer complements the color scheme. Great job overall!
