Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The preferredStyleSheetSet
property returns the preferred style sheet set as set by the page
author.
Value
The author's preferred style sheet set. This is determined from the order of style sheet declarations and the
Default-Style
HTTP header.
If there isn't a preferred style sheet set defined by the author, the empty string (""
) is returned.
Examples
js
if (document.preferredStyleSheetSet) {
console.log(
`The preferred style sheet set is: ${document.preferredStyleSheetSet}`
);
} else {
console.log("There is no preferred style sheet.");
}
