Official HTML standards and internet drafts.
- Machine-readable (DTDs)
- A Document Type Definition (DTD) is a formal way of specifying the valid tags, attributes,
entities, and relationships for a markup language in SGML syntax. DTDs can be used with
validators and SGML-aware editors to create documents which conform to the HTML
specifications. Below are links to all of the current DTDs for HTML. The ``strict'' versions of
DTDs can be used to create documents which avoid the elements of a previous version of HTML
that have since been deprecated.
