The parentStyleSheet property of the StyleSheet interface returns the style sheet, if any, that is including the given style sheet.


objRef = stylesheet.parentStyleSheet 


// Find the top level stylesheet
if (stylesheet.parentStyleSheet) {
  sheet = stylesheet.parentStyleSheet;
} else {
  sheet = stylesheet;


This property returns null if the current stylesheet is a top-level stylesheet or if stylesheet inclusion is not supported.
