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; } }, '');
