Test it in CSS
Prefer breakpoints based on your content over device-specific rules. If you need to reproduce this exact size, for example to debug a layout, this media query matches it in portrait:
@media (width: 420px) and (height: 912px) {
/* iPhone Air, portrait */
}The Dynamic Island cuts into the top of the screen in full-screen layouts. Add viewport-fit=cover to your viewport meta tag, then pad fixed headers with env(safe-area-inset-top) so nothing hides behind it.
