The StyleSheetList interface represents a list of StyleSheet.

It is an array-like object but can't be iterated over using Array methods. However It can be iterated over in a standard for loop over its indices, or converted to an Array.

Examples

Get document styleSheet objects with for loop

for (var i=0; i < document.styleSheets.length; i++){
  var styleSheet = document.styleSheets[i];
}

Get all CSS rules for the document using Array methods

var allCSS = 
    [].slice.call(document.styleSheets)
        .reduce(function (prev, styleSheet) {
            if (styleSheet.cssRules) {
                return prev +
                    [].slice.call(styleSheet.cssRules)
                        .reduce(function (prev, cssRule) {
                            return prev + cssRule.cssText;
                        }, '');
            } else {
                return prev;
            }
        }, '');
