This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes.

The device-width CSS media feature can be used to test the width of an output device's rendering surface.

Syntax

The device-width feature is specified as a <length> value. It is a range feature, meaning that you can also use the prefixed min-device-width and max-device-width variants to query minimum and maximum values, respectively.

Examples

Applying a special stylesheet for devices that are narrower than 800 pixels

<link rel="stylesheet" media="screen and (max-device-width: 799px)" href="http://foo.bar.com/narrow-styles.css" />
