The iPhone X (2018) boasts a pixel density of 3, which translates to a Retina display. This high pixel density results in sharp, clear images and text, enhancing the overall visual experience. Web developers can target devices with this pixel density using CSS media queries:
@media only screen and (-webkit-min-device-pixel-ratio: 3) {
/* CSS rules for devices with a pixel density of 3 or higher */
}
This media query allows developers to apply specific styles to ensure that images and other visual elements look their best on high-resolution displays like the iPhone X. In JavaScript, the pixel density can be retrieved using the `window.devicePixelRatio` property.
Manufacturer’s Resolution
Given the iPhone X’s pixel density of 3, the manufacturer’s resolution is 1125 pixels in width and 2436 pixels in height. This higher resolution is what the device’s hardware actually renders, which is then scaled down to fit the viewport. Understanding both the viewport resolution and the manufacturer’s resolution is crucial for optimizing websites and applications for the iPhone X. This is similar to how Huawei P30 Pro features were designed to take advantage of its display capabilities.
