DOM Document Object

Definition and Usage

The Document object is the root of a document tree.

The Document object gives us access to the document's data.

Since element nodes, text nodes, attributes, comments, etc. cannot exist outside the document, the Document object contains methods to create these objects. All Node objects have a ownerDocument property which associates them with the Document where they were created.

Note: The Document object can also use the properties and methods of the Node object.

Browser Support

The Document object is supported in all major browsers.
