width
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The width
CSS media feature can be used to test the width of the viewport (or the page box, for paged media).
Syntax
The width
feature is specified as a <length>
value representing the viewport width. It is a range feature, meaning that you can also use the prefixed min-width
and max-width
variants to query minimum and maximum values, respectively.
Examples
HTML
html
<div>Watch this element as you resize your viewport's width.</div>
CSS
css
/* Exact width */
@media (width: 360px) {
div {
color: red;
}
}
/* Minimum width */
@media (min-width: 35rem) {
div {
background: yellow;
}
}
/* Maximum width */
@media (max-width: 50rem) {
div {
border: 2px solid blue;
}
}
