An HTML element is any entity enclosed in angle brackets (< and >) interpreted as HTML, for example a, img, html, and body.
This class is an abstract base class that defines the interface for all HTMLElement subclasses.

An HTMLElement is either atomic, meaning it has no corresponding closing tag (elements such as hr and br are atomic) or boolean (elements such as a and ol are boolean)
