The CSSStyleDeclaration.parentRule read-only property returns a CSSRule that is the parent of this style block, e.g. a CSSStyleRule representing the style for a CSS selector.


var rule = styles.parentRule;


The CSS rule that contains this declaration block or null if this CSSStyleDeclaration is not attached to a CSSRule.


The following JavaScript code gets the parent CSS style rule from a CSSStyleDeclaration:

var declaration = document.styleSheets[0].rules[0].style;
var rule = declaration.parentRule;
