A special tag that allows browsers that don't support scripting to display alternative content.
JScript - 3.0
Internet Explorer - 4.0
Netscape - 3.0
Browsers that support the <SCRIPT> tag should also support the <NOSCRIPT> tag. However, their support for the <NOSCRIPT> tag should be to hide or ignore anything between the <NOSCRIPT> tag and its corresponding </NOSCRIPT> closure.
