Examples
The CSS below includes a media query with one style rule.

).
myRules[0]

<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}`;
