Document: preferredStyleSheetSet property

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

if (document.preferredStyleSheetSet) {
  console.log(
    `The preferred style sheet set is: ${document.preferredStyleSheetSet}`,
  );
} else {
  console.log("There is no preferred style sheet.");
}
