The media property of the StyleSheet interface specifies the intended destination media for style information. It is a read-only, array-like MediaList object and can be removed with deleteMedium() and added with appendMedium().
A read-only array-like MediaList object.
Assume the <head> contains the following:
<link rel="stylesheet" href="document.css" media="screen" />
<style rel="stylesheet" media="screen, print">
body {
background-color: snow;
}
</style>
Then:
for (let i = 0; i < document.styleSheets.length; i++) {
console.log(
`document.styleSheets[${i}].media: ${JSON.stringify(
document.styleSheets[i].media,
)}`,
);
if (i === 0) document.styleSheets[i].media.appendMedium("handheld");
if (i === 1) document.styleSheets[i].media.deleteMedium("print");
console.log(
`document.styleSheets[${i}].media: ${JSON.stringify(
document.styleSheets[i].media,
)}`,
);
}
// This will log:
// document.styleSheets[0].media: {"0":"screen"}
// document.styleSheets[0].media: {"0":"screen","1":"handheld"}
// document.styleSheets[1].media: {"0":"screen","1":"print"}
// document.styleSheets[1].media: {"0":"screen"}
