DHTML ,DHTML is NOT a language, DHTML is a TERM describing the art of making dynamic and interactive web pages,DHTML combines HTML, JavaScript, the HTML DOM, and CSS.
web page using DHTML is set up the following way:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>DHTML example</title>
<script type="text/javascript">
function init() {
myObj = document.getElementById("navigation");
// .... more code
}
window.onload=init;
</script>
</head>
<body>
<div id="navigation"></div>
<pre>
Often the code is stored in an external file; this is done by linking the file that contains the JavaScript.
This is helpful when several pages use the same script:
</pre>
<script type="text/javascript" src="myjavascript.js"></script>
</body>
</html>
