Properties

XMLNS attribute
:

childElementCount: Returns the number of direct children of this node that are elements. Read-only.
children: Retrieves a live collection of child elements of an element.
classList: Reflects the class attribute as an ordered list of the whitespace separated class names and has convenience methods for add, remove, contains and more.

internalSubset
:

lastElementChild: Retrieves the last child of this node that is an element, if there are any element children, or null otherwise. Read-only.

nextElementSibling: Retrieves the element node that is a sibling to this element node (a direct child of the same parent) and is immediately after it in the DOM tree, ignoring text nodes, comment nodes and any other non-element nodes. If there is no next element sibling, the property value is null. Read-only.

parentElement: Retrieves the parent node of this DOM node, if the parent is an element node; null if the parent is not an element or if there is no parent. Read-only.
