Document: lastStyleSheetSet property

The Document.lastStyleSheetSet property returns the last enabled style sheet set. This property’s value changes whenever the selectedStyleSheetSet property is changed.

Value

The style sheet set that was most recently set. If the current style sheet set has not been changed by setting selectedStyleSheetSet, the returned value is null.

[!NOTE] This value doesn’t change when enableStyleSheetsForSet() is called.

Examples

let lastSheetSet = document.lastStyleSheetSet;

if (!lastSheetSet) {
  lastSheetSet = "Style sheet not yet changed";
} else {
  console.log(`The last style sheet set is: ${lastSheetSet}`);
}
