Document.styleSheetSets

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

Syntax

var sets = document.styleSheetSets;

On return, sets is a list of style sheet sets that are available.

Example

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:

let list = document.getElementById('sheetList');
let sheets = document.styleSheetSets;

list.innerHTML = '';

for (let i = 0; i < sheets.length; i++) {
  let item = document.createElement('li');

  item.innerHTML = sheets[i];
  list.appendChild(item);
}

Notes

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).
