The HTML <noscript> tag is used for providing alternative content for browsers that don't support javascript or other scripting languages.
The <noscript> tag is used in conjunction with the <script> tag.
Defines content to be used when a script can not be used (either because a browser does not support it or a user has switched off that functionality).
<script type="text/javascript"> [some JavaScript here] </script> <noscript> <p>You browser don't support JavaScript</p> </noscript>
