<script> ... </script>

The script tag is used to place script code inside the head and body elements of an HTML code document. For all practical purposes, this tag is primarily used to allow the execution of JavaScript code inside HTML code (and, to a lesser extent, VBScript).

The separate closing tag is mandatory.
