The Node.parentElement read-only property returns the DOM node's parent Element, or null if the node either has no parent, or its parent isn't a DOM Element.
parentElement = node.parentElement
parentElement is the parent element of the current node. This is always a DOM Element object, or null.
if (node.parentElement) {
node.parentElement.style.color = "red";
} On some browsers, the parentElement property is only defined on nodes that are themselves an Element. In particular, it is not defined on text nodes.
