<noframes>: the "Frame Fallback" element

Deprecated: This feature is no longer recommended. While some browsers may still support it, it may have already been removed from relevant web standards, may be in the process of being phased out, or may be retained only for compatibility reasons. Avoid using it and, if possible, update existing code. Please note that this feature may stop working at any time.

The HTML <noframes> element provides content to be presented in browsers that do not support (or have disabled support for) the <frame> element. While the most commonly used browsers support frames, exceptions exist, including some special-purpose browsers, including some mobile browsers, as well as text-mode browsers.

A <noframes> element can contain any HTML element allowed within the body of an HTML document, except for the <frameset> and <frame> elements, since using frames when they are not supported makes no sense.

<noframes> can be used to present a message explaining that the user's browser does not support frames, but ideally should be used to present an alternative form of the site that does not use frames but still offers the same or similar functionality.

Note: This element is deprecated and should not be used, as the <frame> and <frameset> elements are also deprecated. When frames are necessary, they should be presented using the <iframe> element.
