HTML and XHTML
- HTML
- (Hypertext Markup Language) - HTML is the lingua franca for publishing hypertext on
the World Wide Web. It is a non-proprietary format based upon
SGML, and
can be created and processed by a wide range of tools, from simple plain
text editors - you type it in from scratch- to sophisticated WYSIWYG authoring tools.
HTML uses tags such as
<h1>and</h1>to structure text into headings, paragraphs, lists, hypertext links etc. Here is a 10-minute guide for newcomers to HTML. W3C's statement of direction for HTML is given on the HTML Activity Statement. See also the page on our work on the next generation of Web forms, and the section on Web history.

- XHTML
- The Extensible HyperText Markup Language (XHTML™) is a family
of current and future document types and modules that reproduce, subset, and
extend HTML, reformulated in XML.
XHTML Family document types are all XML-based, and ultimately
are designed to work in conjunction with XML-based user agents.
XHTML is the successor of HTML, and a series
of specifications has been developed for XHTML.
