QR Layout Using Plain CSS and HTML

The challenging part was vertically centering the card. I ended up using 'vh' and 'vw' to size the card. I noticed that when I specified height to 100% on card to get to center vertically it didn't work, however, after I had changed from percentage to 'vh' it seemed to work. Other than that I couldn't get it an exact match with the specified font size on the paragraph element (Ended up making it a bit bigger). I do notice that it does not respond to smaller sizes, but the challenge didn't require a responsive design. Hopefully, the solution I chose is NOT terribly done.
