The media read-only property of the MediaQueryList interface is a DOMString representing a serialized media query.


var media =;


A DOMString representing a serialized media query.


This example runs the media query (max-width: 600px) and  displays the value of the resulting MediaQueryList's media property in a <span>.


let mql = window.matchMedia('(max-width: 600px)');

document.querySelector(".mq-value").innerText =;

The JavaScript code simply passes the media query to match into matchMedia() to compile it, then sets the <span>'s innerText to the value of the results' media property.


<span class="mq-value"></span>

A simple <span> to receive the output.
