HTMLFrameSetElement
The interface for <frameset>. Extends HTMLElement → Element.
Deprecated. HTMLFrameSetElement covers an obsolete element (WHATWG HTML §16.3 "Other elements, attributes and APIs"); it exists only for instanceof / constructor.name fidelity and content-attribute reflection, not for use in new content.
