Document.lastStyleSheetSet

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 Document.lastStyleSheetSet property returns the last enabled style sheet set. This property's value changes whenever the 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 document.selectedStyleSheetSet, the returned value is null.

Note: This value doesn't change when 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}`);
}
