<h2>Abstract</h2>
<p>This specification defines the HyperText Markup Language (HTML),
version 4.0, the publishing language of the World Wide Web. In addition
to the text, multimedia, and hyperlink features of the previous versions
of HTML, HTML 4.0 supports more multimedia options, scripting languages,
style sheets, better printing facilities, and documents that are more
accessible to users with disabilities. HTML 4.0 also takes great strides
towards the internationalization of documents, with the goal of making
the Web truly World Wide.
<p>HTML 4.0 is an SGML application conforming to International
Standard ISO 8879 -- Standard Generalized Markup Language <a
rel="biblioentry" href="./references.html#ref-ISO8879"
class="normref">[ISO8879]</a>.</p>
<h2>Status of this document</h2>
<P>This document has been reviewed by W3C Members and other interested
parties and has been endorsed by the Director as a W3C
Recommendation. It is a stable document and may be used as reference
material or cited as a normative reference from another
document. W3C's role in making the Recommendation is to draw attention
to the specification and to promote its widespread deployment. This
enhances the functionality and interoperability of the Web.
<P>W3C recommends that user agents and authors (and in particular,
authoring tools) produce HTML 4.0 documents rather than HTML 3.2
documents (see <a rel="biblioentry"
href="./references.html#ref-HTML32" class="informref">[HTML32]</a>).
For reasons of backwards compatibility, W3C also recommends that tools
interpreting HTML 4.0 continue to support HTML 3.2 and HTML 2.0 as
well.
<P>A list of current W3C Recommendations and other technical documents
can be found at <a href="http://www.w3.org/TR">http://www.w3.org/TR</a>.
<P>Public discussion on HTML features takes place on <a
href="http://www.w3.org/MarkUp/Forums#www-html">www-html@w3.org</a>.
