Targeting the Samsung Galaxy S8 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.
/* Target Samsung Galaxy S8 specifically */
@media only screen
and (device-width: 360px)
and (device-height: 740px)
and (-webkit-device-pixel-ratio: 4) {
/* … */
}
/* More useful in practice — the width bucket it falls into */
@media (min-width: 360px) { /* … */ }Compare with other Android Phones models
