For web developers
CSS viewport: 320 × 480 CSS pixels in portrait, devicePixelRatio 1. CSS pixels equal points.
/* iPhone (1st generation), portrait */
@media (device-width: 320px) and (device-height: 480px) and (-webkit-device-pixel-ratio: 1) {
/* styles for this screen size */
}/* needs <meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover"> */
.page { padding: env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left); }
/* this device's insets aren't measured yet */Safari's visible viewport is smaller than the screen because of the browser bars, so window.innerHeight is less than the height above until the bars collapse.
For iOS developers
- A 1 pt line is 1 pixel thick.
- A 44 pt tap target is 44 × 44 pixels.
- Assets: @1x.
UIScreen.main.bounds: 320 × 480 points (portrait).UIScreen.main.scale: 1.
