XHTML

A.XHTML Reference

XHTML uses the tags and attributes of HTMLalong with

the syntax of XML. For the most part, you will use the same tags and attri-

butes in HTML and XHTML; the major change is the syntax and additional

restrictions in XHTML. This section provides an introduction to XML syntax

and a detailed list of XHTML tags and attributes.

You will notice that a number of XHTML elements and attributes are depre-

cated, which means that they are currently supported but will be removed from

the language in the future. Most of the deprecated elements relate to presenta-

tion features such as alignment text configuration. The W3C recommends using

CSS to replace the functionality of the deprecated components. This section will

be helpful as a reference as you design Web pages. It contains five major areas:

●XML Syntax

●General XHTML 1.0 Syntax Guidelines

●Basic Tags

●Header Section Tags

●Body Section Tags

A.1 XML Syntax

An XML document must be well formed. A well-formed document is a docu-

ment that adheres to the syntax rules of the language. Here are the key syntax

rules of XML:

●XML is case-sensitive.

●An XML document must contain one or more elements.

●All XML elements must have an opening tag and a closing tag. All tags

are enclosed in angle brackets.
