Value

A MediaList object.

Although the media property itself is read-only in the sense that you can't replace the MediaList object, you can still assign to the media property directly, which is equivalent to assigning to its mediaText property. You can also modify the MediaList object using the appendMedium() and deleteMedium() methods.

Examples

Getting the media property

The following stylesheet includes a single @import rule. Therefore the first item in the list of CSS rules will be a CSSImportRule. The media property returns a MediaList object. This includes the mediaText property with a value of screen.

@import "style.css" screen;

const myRules = document.styleSheets[0].cssRules;
console.log(myRules[0].media); // A MediaList

Setting the media property

To change the media attribute of the associated stylesheet, set the value of media to a string containing the new value.

const myRules = document.styleSheets[0].cssRules;
myRules[0].media = "print";
