This appendix is a reference to the HTML tags you can use in your documents, according to the HTML 2.0 Specification. In addition, tags defined in both the HTML 3.2 and Netscape Navigator 2 specification are listed. Tag supported by HTML 3.2 and Navigator 2 are listed as (HTML 3.2), while tags that are currently only available in Navigator 2 are listed as (NHTML). There are also several of tags listed that Navigator 2.0 does not yet support. These are listed as (HTML 3.2 only).
Note:
If you are new to HTML and Web publishing, you should obtain a copy of my book Teach Yourself Netscape 2 Web Publishing in a Week for a more detailed coverage of Web publishing techniques.
This section covers all of the major tags relating to publishing text on a Web page. This includes all the document formatting tags, character formatting tags, and paragraph formatting tags.
Comments tags are special tags that have no effect on the appearance or content of a Web page. They exist entirely for descriptive or informative purposes.
Any text enclosed within a comment tag is completely ignored by the Web browser. This includes tags, elements, and entities.
Used with HTML document validation systems such as Halsoft at http://www.halsoft.com/html-val-svc/ to indicate the level of HTML support included in a document. If included in a document, this tag must be placed on the very first line, before the <HTML> tag.
Used to indicate a more strict set of compliance tests for validation systems such as Halsoft. For more information, visit the Halsoft site listed previously. This site contains both the document validation system and a range of files covering document type definitions (DTD) and HTML standards.
The structure tags do not affect the actual appearance of a Web page, but are instead used to define separate section of the HTML code used when writing a Web page.
