Document: lastStyleSheetSet property

{{APIRef("DOM")}}{{deprecated_header}}{{Non-standard_header}}

The Document.lastStyleSheetSet property returns the last enabled style sheet set. This property's value changes whenever the {{domxref("document.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 {{domxref("document.selectedStyleSheetSet")}}, the returned value is null.

[!NOTE] This value doesn't change when {{domxref("document.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}`);
}
