Good job on completing the challenge, @slasher314 !
I have a few suggestions that I hope will be useful to you based on your final solution:
background-repeat: no-repeatto your body so the background image doesn't repeat itself
Try vertically centering your design https://www.youtube.com/watch?v=njdJeu95p6s&ab_channel=Fireship
Add some more vertical padding to the "Proceed to payment" button
Adjust the box-shadow for the "Proceed to payment" button. The x and y offset are too high and the blur value should be higher
On smaller screen sizes, you should reduce the card's dimension a bit. Also, at around 390px resolution, you can see the card isn't horizontally centered so try to fix that as well
Hope this helps. Keep up the great work!
