monochrome

The monochrome CSS @media media feature can be used to apply styles based on 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>How many bits does your device support for monochrome pixels?</p>

CSS

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

/* Any non-monochrome device */
@media (monochrome: 0) {
  p {
    color: #ee3636;
  }
}
