StyleSheet: media property

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 read-only media property of the StyleSheet interface contains a MediaList object representing the intended destination media for style information.

Value

A MediaList object. Its value is set by the media attribute on the corresponding <link> or <style> element. If the media attribute is not set or empty, it returns an empty MediaList, i.e., a MediaList with the length property equal to 0.

Although the media property itself is read-only in the sense that you can't replace the MediaList object, you can still assign to the media property directly, which is equivalent to assigning to its mediaText property. You can also modify the MediaList object using the appendMedium() and deleteMedium() methods.

Examples

Assume the <head> contains the following:

html
<link rel="stylesheet" href="document.css" media="screen" />
<style rel="stylesheet" media="screen, print">
  body {
    background-color: snow;
  }
</style>

Then:

js
for (let i = 0; i < document.styleSheets.length; i++) {
  console.log(
    `document.styleSheets[${i}].media: ${JSON.stringify(
      document.styleSheets[i].media,
    )}`,
  );
  if (i === 0) document.styleSheets[i].media.appendMedium("handheld");
  if (i === 1) document.styleSheets[i].media.deleteMedium("print");
  console.log(
    `document.styleSheets[${i}].media: ${JSON.stringify(
      document.styleSheets[i].media,
    )}`,
  );
}
// This will log:
// document.styleSheets[0].media: {"0":"screen"}
// document.styleSheets[0].media: {"0":"screen","1":"handheld"}
// document.styleSheets[1].media: {"0":"screen","1":"print"}
// document.styleSheets[1].media: {"0":"screen"}
