monochrome

The monochrome CSS media feature can be used to test the number of bits per pixel in the monochrome frame buffer of the output device.

Syntax

The monochrome feature is specified as an <integer> representing the number of bits per pixel in the monochrome frame buffer. If the device is not a monochrome device, the value is zero. It is a range feature, meaning that you can also use the prefixed min-monochrome and max-monochrome variants to query minimum and maximum values, respectively.

Example

HTML

<p class="mono">Your device supports monochrome pixels!</p>
<p class="no-mono">Your device doesn't support monochrome pixels.</p>

CSS

p {
  display: none;
}

/* Any monochrome device */
@media (monochrome) {
  p.mono {
    display: block;
    color: #333;
  }
}

/* Any non-monochrome device */
@media (monochrome: 0) {
  p.no-mono {
    display: block;
    color: #ee3636;
  }
}
