XHTML (EXtensible HyperText Markup Language):

Introduction:

XHTML is almost identical to HTML 4.01. XHTML is a stricter and cleaner version of HTML. XHTML is a combination of HTML and XML (EXtensible Markup Language). XHTML consists of all the elements in HTML 4.01 combined with the syntax of XML. XML is a markup language where everything has to be marked up correctly, which results in "well-formed" documents. XML was designed to describe data and HTML was designed to display data. All new browsers have support for XHTML.

The Most Important Differences:

* XHTML elements must be properly nested

* XHTML elements must always be closed

* XHTML elements must be in lowercase

* XHTML documents must have one root element

The basic document structure is:

<html>

<head> ... </head>

<body> ... </body>

</html>

Some More XHTML Syntax Rules:

* Attribute names must be in lowercase

* Attribute values must be quoted

* Attribute minimization is forbidden

* The id attribute replaces the name attribute

Tags: <!--...--> - Defines a comment

<html> - Defines an html document

<head> - Defines information about the document

<title> - Defines the document title

<body> - Defines the body element

<p> - Defines a paragraph

<h1>..<h6> - Defines header 1 to header 6

<font> - Defines text font, size, and color

<a> - Defines an anchor

<b> - Defines bold text

<big> - Defines big text

<br> - Inserts a single line break

<div> - Defines a section in a document

<hr> - Defines a horizontal rule

<i> - Defines italic text

<img> - Defines an image

<ol> - Defines an ordered list

<ul> - Defines an unordered list

<li> - Defines a list item

<span> - Defines a section in a document

<table> - Defines a table

<th> - Defines a table header

<td> - Defines a table cell

<u> - Defines underlined text

<input> - Defines an input field

CSS (Cascading Style Sheets):

Styles define how to display HTML elements

Styles are normally stored in Style Sheets

Styles were added to HTML 4.0 to solve a problem

External Style Sheets can save you a lot of work

External Style Sheets are stored in CSS files as ".css"

Multiple style definitions will cascade into one

XHTML with Javascript:

JavaScript is used in millions of Web pages to improve the design, validate forms, detect browsers, create cookies, and much more. JavaScript is the most popular scripting language on the internet, and works in all major browsers, such as Internet Explorer, Firefox, and Opera. A scripting language is a lightweight programming language. JavaScript is usually embedded directly into HTML pages. JavaScript is an interpreted language (means that scripts execute without preliminary compilation)

JavaScript gives HTML designers a programming tool - HTML authors are normally not programmers, but JavaScript is a scripting language with a very simple syntax! Almost anyone can put small "snippets" of code into their HTML pages

JavaScript can put dynamic text into an HTML page - A JavaScript statement like this : document.write("<h1>" + name + "</h1>") can write a variable text into an HTML page

JavaScript can react to events - A JavaScript can be set to execute when something happens, like when a page has finished loading or when a user clicks on an HTML element

JavaScript can read and write HTML elements - A JavaScript can read and change the content of an HTML element

JavaScript can be used to validate data - A JavaScript can be used to validate form data before it is submitted to a server. This saves the server from extra processing

JavaScript can be used to detect the visitor's browser - A JavaScript can be used to detect the visitor's browser, and - depending on the browser - load another page specifically designed for that browser

JavaScript can be used to create cookies - A JavaScript can be used to store and retrieve information on the visitor's computer.
