Targeting the Samsung Galaxy S25 Ultra in CSS

Device-specific media queries are brittle — a new model with the same width will not match. Use them for genuine per-device fixes only, and prefer width buckets for layout.

CSS media query
/* Target Samsung Galaxy S25 Ultra specifically */
@media only screen
  and (device-width: 480px)
  and (device-height: 1040px)
  and (-webkit-device-pixel-ratio: 3) {
  /* … */
}

/* More useful in practice — the width bucket it falls into */
@media (min-width: 480px) { /* … */ }
