`resolution` CSS media feature

The resolution CSS media feature can be used to test the pixel density of the output device.

Syntax

The resolution feature is specified as a 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.

Examples

HTML

<p>This is a test of your device's pixel density.</p>

CSS

/* 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;
  }
}
