-- THE BARE BONES GUIDE TO HTML --

Version 4.0 Formatted -- February 1999

The latest version of this document is available at http://werbach.com/barebones/, where you will also find the text version, translations, and background materials.

The Bare Bones Guide to HTML lists all the tags that current browsers are likely to recognize. I have included all the elements in the official HTML 4.0 recommendation with common attributes, as well as Netscape and Microsoft extensions. This document is a quick reference, not a complete specification; for official information about HTML and its development, see the World Wide Web Consortium site at http://www.w3.org/MarkUp/.

The Guide is designed to be as concise as possible, and therefore it doesn't go into any detail about how to use the various tags. A few tags link to notes that address frequently-asked questions. If you're looking for more detailed step-by-step information, see my WWW Help Page.

Table of Contents

  1. INTRODUCTORY MATERIAL
  2. HTML TAGS

    Important: If you are not clear about the differences between the various versions of HTML, I suggest that you read my discussion of the development of HTML, or the World Wide Web Consortium HTML activity statement.
