What Is a SCRIPT Tag/Element? - XHTML 1.0 Tutorials - Understanding In-line Elements and Tags

A "script" element is both an inline element and a block element that you can use to specify a script code to be executed by browsers. Here are basic rules about "script" elements:

• "script" elements are inline elements.
• "script" elements are also block elements.
• Most browsers will executed contents of "script" elements as script code.

Below is a good tutorial example of using "script" elements:

<?xml version="1.0" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
 <head>
  <title>SCRIPT Elements</title>
 </head>
 <body>
  <p>Let's ask the browser to calculate: <br/>
  sqrt(2.0) = <script type="text/javascript">
  document.write(Math.sqrt(2.0))
  </script></p>
 </body>
</html>

If you save the above document as inline_script.html, and view it with Internet Explorer, you will see that the browser calculates sqrt(2.0) correctly and displays the result as shown below:
