What is HTML?
Web document markup. User files are shown as source text and never executed.
Technical details
HTML uses elements and attributes in a document tree; parsing follows HTML tokenization and tree-construction rules rather than XML well-formedness rules. [1]
Background and compatibility
The WHATWG Living Standard is the browser-oriented HTML specification; .htm is a common extension alias for the same language. [1]
