device-width
CSS
media feature
can be used to test the width of an output device's rendering surface.
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.
<link rel="stylesheet" media="screen and (max-device-width: 799px)" href="http://foo.bar.com/narrow-styles.css" />
