CSS for the iPhone 17 Pro Max

Media query by width

Breakpoints are written in CSS pixels, never in physical resolution.

/* iPhone 17 Pro Max: 440 CSS px in portrait, 956 in landscape */
@media (max-width: 440px) {
  /* … */
}

/* screens with a DPR of 3 or more */
@media (min-resolution: 3dppx) {
  /* 3x images */
}

Safe areas with env()

With viewport-fit=cover, the page runs to the edge and the system hands over the safe areas through env(). In the installed app, the top only becomes an inset with the black-translucent status bar; in Safari, the browser bars cover those strips.

<meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover">
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">

/* iPhone 17 Pro Max, portrait: 62 px at the top and 34 px at the bottom */
.header { padding-top: env(safe-area-inset-top); }
.bottom-bar { padding-bottom: env(safe-area-inset-bottom); }

/* landscape: 62 px on the sides and 21 px at the bottom */
.page {
  padding-left: max(16px, env(safe-area-inset-left));
  padding-right: max(16px, env(safe-area-inset-right));
}

How Breakpane emulates the iPhone 17 Pro Max

Breakpane doesn't run iOS. It's Chromium with the iPhone 17 Pro Max's viewport (440×956), density (3), user agent, touch, safe areas and display-mode, inside a frame with the real dimensions, floating in front of your editor with your dev server live.

It covers layout, safe areas and the installed PWA. WebKit rendering or API bugs only show up on a real device or in the Xcode Simulator.
