HTML Specification

An SGML Application Conforming to International Standard ISO 8879 -- Standard Generalized Markup Language

This specification describes the current standards of HyperText Markup Language (HTML). It is a draft of a standard for interchange of information on the network which is proposed to be registered as a MIME (RFC1521) content type.

HTML Document Type Definitions, including the SGML Declaration for HTML, are provided at the end of this specification. This documentation also includes the HTML DTD Reference (Level 2) and the HTML DTD Reference (Level 0).

This version of the HTML specification (Version 2.0, released July 31, 1994) introduces forms for user input of information, and adds a distinction between levels of conformance:

Level 0

Indicates the minimum conformance level. When writing documents at Level 0, authors can have a high level of confidence that the rendering at different sites will reflect their intent.

Level 1

Includes Level 0 features plus features such as highlighting and images.

Level 2

Includes all Level 0 and Level 1 features, plus forms. Features of higher levels which are under discussion, (such as tables, figures, and mathematical formulae) where mentioned are described as proposed.
