HTML Interface

HTML DOM API interfaces

The majority of the interfaces that comprise the HTML DOM API map almost one-to-one to individual HTML elements, or to a small group of elements with similar functionality. In addition, the HTML DOM API includes a few interfaces and types to support the HTML element interfaces.
