Although you can create and edit HTML/XHTML documents with a text editor, such as vi or Notepad, most HTML authors use an application that is designed for creating web pages—several are free of charge, many offer a free evaluation period, and most are available for download over the Web. Be forewarned, though; in our experience, you will rarely (if ever) be able to create a web document from one of these editors without having to inspect, add to, edit, and sometimes even repair the source HTML that the editor generates. The following sections discuss a few things that you should know about and watch out for.

<html> <head> <title>My first HTML document</title> </head> <body> <h2>My first HTML document</h2> Hello, <i>World Wide Web!</i> <!-- No "Hello, World" for us --> <p> Greetings from<br> <a href="http://www.ora.com">O'Reilly Media</a> <p> Composed with care by: <cite>(insert your name here)</cite> <br>©2000 and beyond </body> </html>
