The preferredStyleSheetSet
property returns the preferred style sheet set as set by the page author.
Syntax
preferredStyleSheetSet = document.preferredStyleSheetSet
On return, preferredStyleSheetSet
indicates 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.
Example
if (document.preferredStyleSheetSet) { console.log("The preferred style sheet set is: " + document.preferredStyleSheetSet); } else { console.log("There is no preferred style sheet."); }
