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 CSSMediaRule interface returns a MediaList representing the intended destination medium for style information.
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 (width >= 500px) {
body {
color: blue;
}
}
let myRules = document.styleSheets[0].cssRules; console.log(myRules[0].media); // a MediaList
