The device-width CSS @media media feature can be used to apply styles based on the width of the rendering surface of the output device.
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.
This HTML applies 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" />
