Element

A interface Element representa um objeto de um Document. Esta interface descreve métodos e propriedades comuns a todos os tipos de elementos. Specific behaviors are described in interfaces which inherit from Element but add additional functionality. For example, the HTMLElement interface is the base interface for HTML elements, while the SVGElement interface is the basis for all SVG elements.

Languages outside the realm of the Web platform, like XUL through the XULElement interface, also implement it.

Specifications

Browser compatibility

[1] Internet Explorer 7 and 8 incorrectly return the comments as part of the children of an Element. This is fixed in Internet Explorer 9 and later.

[2] Chrome 16 allowed webkitRequestPointerLock() only in fullscreen; Chrome 21 for trusted web site (permission asked);  Chrome 22 allowed it by default for all same-origin document; Chrome 23 allowed it in sandboxed <iframe> if the non-standard value webkit-allow-pointer-lock is set to the sandbox attribute.
