Document Type Declaration

Test Weight: normal
HTML is only one of a series of markup languages, though it is the best known one. HTML is relatively old and has seen various, rather different variations. The Document Type Declaration indicates which markup language and which version of it has been used. A sorting software, e.g. a web browser, can understand this indication.
