  mobile (375px), desktop (1440px) = use of media query; there is no such thing as margin: center; You might have confused it with margin : auto; But margin: auto; will only work for centering horizontal space on block level element.

  My advice: Look at

  1. Box Modal and
  2. media Query

  "I thought if I put margin: center, the whole white layout together with the QR code will move to the middle " If you mean centering the div then look at:

  1. Flex-centering
  2. Grid-centering
  3. position-Absolute.
