Document: styleSheetSets property

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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 styleSheetSets read-only property returns a live list of all of the currently-available style sheet sets.


A list of style sheet sets that are available.


Given an <ul> (list) element with the ID "sheetList", you can populate it with the names of all the available style sheet sets with code like this:

const list = document.getElementById("sheetList");
const sheets = document.styleSheetSets;

list.textContent = "";

for (const sheet of sheets) {
  const item = document.createElement("li");
  item.textContent = sheet;


The list of available style sheet sets is constructed by enumerating all the style sheets available for the document, in the order in which they're listed in the Document.styleSheets attribute, adding the title of each style sheet that has a title to the list. Duplicates are dropped from the list (using a case-sensitive comparison).
