rule.

, and CSSRule
.
CSSMediaRule.media
Read only
Returns a MediaList
representing the intended destination medium for style information.
No specific methods; inherits methods from its ancestors CSSConditionRule
, CSSGroupingRule
, and CSSRule
.
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
.
@media (width >= 500px) {
body {
color: blue;
}
}
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}`;
