Targeting the iPad Pro 12.9″ (3rd) 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 iPad Pro 12.9″ (3rd) specifically */
@media only screen
  and (device-width: 1024px)
  and (device-height: 1366px)
  and (-webkit-device-pixel-ratio: 2) {
  /* … */
}

/* More useful in practice — the width bucket it falls into */
@media (min-width: 1024px) { /* … */ }

Safe area on the iPad Pro 12.9″ (3rd)

iPad 13″, home indicator. Content placed inside the top 24 px or the bottom 20 px will sit under system UI unless you inset it.

Safe area insets
/* iPad Pro 12.9″ (3rd) safe area — requires viewport-fit=cover */
<meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover">

.app {
  padding-top:    env(safe-area-inset-top);    /* 24px */
  padding-bottom: env(safe-area-inset-bottom); /* 20px */
  padding-left:   env(safe-area-inset-left);
  padding-right:  env(safe-area-inset-right);
