Have a look at this thread:

You have made some very similar mistakes.
As for your 'tutorial':
Your comments are wrong. What you need is:
<!--This is the beginning of a comment
Any text or code in between the two comments is not looked at when you run the page.
this is the end of a comment-->
As for the rest - where's the doctype? The XML namespace? The
<head></head> tags? The content-tpe META? etc.
As the others have said, it is not a good idea to be teaching HTML
4 to people. There is no good reason why any new document you
create should be anything other than XHTML 1.0 Strict. Here's a
template to get you started.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<style type="text/css">
/*<![CDATA[*/
/*]]>*/
</style>
<script type="text/JavaScript">
/*<![CDATA[*/
/*]]>*/
</script>
</head>
<body>
</body>
</html>
