QR code HTML CSS Bootstrap

Hello to everybody, this is my first challenge here, I hope not the last one) As for hardships, for me it was quite tricky to center the content on the page, first of all vertically. In order to do so I used stretching the outer block to 100% (height: vh-100) from Bootstrap classes + margin 0 auto for inner class. I think there are more ways to do so and I would appreciate if you share your solutions. Thanks!
