The ParentNode mixin contains methods and properties that are common to all types of Node objects that can have children. It's implemented by Element, Document, and DocumentFragment objects.
See Locating DOM elements using selectors to learn how to use CSS selectors to find nodes or elements of interest.

|---|---|---|
| DOM The definition of 'ParentNode' in that specification. | Living Standard | Split the ElementTraversal interface into ChildNode and ParentNode. The ParentNode.firstElementChild, ParentNode.lastElementChild, and ParentNode.childElementCount properties are now defined on the latter. Added the ParentNode.children property, and the ParentNode.querySelector(), ParentNode.querySelectorAll(), ParentNode.append(), and ParentNode.prepend() methods. |
| Element Traversal Specification The definition of 'ElementTraversal' in that specification. | Obsolete | Added the initial definition of its properties to the ElementTraversal pure interface and used it on Element. |
