More reference

If your browser does not support scripting (mainly JavaScript) or if JavaScript is disabled, the text inside the <noscript> and </noscript> tags will be displayed in the active web browser. If the browser supports scripting, the <noscript> content will not be shown.

In HTML 4.01, there was a strict rule that the position of the <noscript> element must be inside the <head> element only. In HTML5, this rule changed. This tag can now be placed in either the <head> section or the <body> section (with content restrictions in <head>).

In XHTML, the <noscript> element is not supported.
