The read-only media property of the CSSMediaRule interface MediaList represents the intended destination medium for style information.


var media = CSSMediaRule.media;


a MediaList


The CSS includes a media query with one style rule. This will be the first CSSRule returned by document.styleSheets[0].cssRules. Calling myRules[0].media therefore returns a MediaList object representing the media query.

@media (min-width: 500px) {
  body {
    color: blue;
let myRules = document.styleSheets[0].cssRules;
console.log(myRules[0].media); // a MediaList
