  • property is a DOMString representing the property name to be checked.

Return value

  • priority is a DOMString that represents the priority (e.g. "important") if one exists. If none exists, returns the empty string.


The following JavaScript code checks whether margin is marked as important in a CSS selector rule:

var declaration = document.styleSheets[0].cssRules[0].style;
var isImportant = declaration.getPropertyPriority('margin') === 'important';
