HTML 5 <noscript> tag
Definition and Usage
The <noscript> element is used to define an alternate content (text) if a script is
NOT executed.
The <noscript> element does not do anything, but is used for browsers that recognizes the <script> tag, but
does not support the script in it.
Differences Between HTML 4.01 and HTML 5

Tips and Notes
Note: If a browser supports scripting, it will not display the text
in the noscript element.
Note: Browsers that do not recognize the <script> tag will display the
tag's content as text on the page. To prevent the browser from doing this, you
should hide the script in comment tags. An old browser (one that does not
recognize the <script> tag) will ignore the comment and will not write the tag's
content on the page, while a new browser will understand that the script should
be executed, even if it is surrounded by comment tags!
