About the HTML 4.0 Specification

1 About the HTML 4.0 Specification

Contents

  1. How to read the specification
  2. How the specification is organized
  3. Acknowledgments

This document has been written with two types of readers in mind: HTML authors and HTML implementors. We hope the specification will provide authors with the tools they need to write efficient, attractive, and accessible documents, without over-exposing them to HTML's implementation details. Implementors, however, should find all they need to build user agents that interpret HTML correctly.

The specification has been written with two modes of presentation in mind: electronic and printed. Although the two presentations will no doubt be similar, readers will find some differences. For example, links will not work in the printed version (obviously), and page numbers will not appear in the electronic version. In case of a discrepancy, the electronic version is considered the authoritative version of the document.

1.1 How to read the specification

The specification may be approached in several ways:

1.2 How the specification is organized

This specification includes the following sections:

Sections 2-3: Introduction to HTML 4.0
The introduction gives an overview of what can be done with HTML 4.0 and provides some design tips for developing good HTML habits.

The brief SGML tutorial gives readers some understanding of HTML's relationship to SGML and gives summary information on how to read the HTML Document Type Definition (DTD).

Sections 4 - 25: HTML 4.0 reference manual
The bulk of the reference manual consists of the HTML language reference, which defines all elements and attributes of the language.

This document has been organized by topic rather than by the grammar of HTML. Topics are grouped into three categories: structure, presentation, and interactivity. Although it is not easy to divide HTML constructs perfectly into these three categories, the model reflects the designers' experience that separating a document's structure from its presentation produces more effective and maintainable documents.

The language reference consists of the following information:

Appendixes
The appendix contains information about changes from HTML 3.2 and performance and implementation notes.
References
Indexes
Two indexes give readers rapid access to the definition of all elements and attributes The indexes also summarize some key characteristics of each element and attribute.
