The parentElement property returns the parent element of the specified element.

The parentElement returns null if the parent node is not an element node: 

document.body.parentNode; // Returns the <html> element 
document.body.parentElement; // Returns the <html> element 
document.documentElement.parentNode; // Returns the Document node document.documentElement.parentElement; // Returns null (<html> does not have a parent ELEMENT node)

This property is read-only.

The parentElement property returns an Element object representing the parent element node of a node, or null if the node has no parent.
