Instance properties

CSSMediaRule.media Read only

Returns a MediaList representing the intended destination medium for style information.

Instance methods

No specific methods; inherits methods from its ancestors CSSConditionRule, CSSGroupingRule, and CSSRule.

Examples

The CSS below includes a media query with one style rule. As this rule lives in the last stylesheet added to the document, it will be the first CSSRule returned by the last stylesheet in the document (document.styleSheets[document.styleSheets.length-1].cssRules). myRules[0] returns a CSSMediaRule object, from which we can get the mediaText.

html
<p id="log"></p>
css
@media (min-width: 500px) {
  body {
    color: blue;
  }
}
js
const log = document.getElementById("log");
const myRules = document.styleSheets[document.styleSheets.length - 1].cssRules;
const mediaList = myRules[0]; // a CSSMediaRule representing the media query.
log.textContent += ` ${mediaList.media.mediaText}`;
