The resolution CSS media feature can be used to test the pixel density of the output device.
The resolution feature is specified as a {{cssxref("resolution")}} value representing the pixel density of the output device. It is a range feature, meaning that you can also use the prefixed min-resolution and max-resolution variants to query minimum and maximum values, respectively.
<p>This is a test of your device's pixel density.</p>
/* Exact resolution with unit `dpi` */
@media (resolution: 150dpi) {
p {
color: red;
}
}
/* Minimum resolution synonym units: `dppx` and `x` */
@media (min-resolution: 2dppx) {
p {
text-decoration: underline;
}
}
@media (min-resolution: 2x) {
p {
text-decoration: underline;
}
}
/* Maximum resolution with unit `dpcm` */
@media (max-resolution: 2dpcm) {
p {
background: yellow;
}
}
