The styleSheetSets read-only property returns a live list of all of the currently-available style sheet sets.
Value
A list of style sheet sets that are available.
Examples
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;
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).
