noframes

Noframes is an HTML element used in conjunction with frameset documents to provide fallback content for browsers that do not support frames or have them disabled. Within a frameset-based page, the frameset element defines multiple subwindows called frames. The content placed inside the noframes element is displayed only when the user agent cannot render frames—for example, when frames are disabled in settings or when the browser lacks frame support.

Noframes can include ordinary HTML content such as text, links, images, and a basic navigation interface. It serves to provide access to information and navigation for users who do not view the page in a frameset layout.

Frames and framesets were common in early web design but have become obsolete in modern HTML. In HTML5, the frameset and its noframes element are deprecated, and most browsers no longer use frameworks-based layouts. Modern development favors responsive designs, single-document layouts, and progressive enhancement, with alternative navigation and content provided without frames.

Legacy pages that use noframes may still rely on it for compatibility, but new work should avoid frames altogether. If present, the noframes content should be reviewed and replaced with accessible, framework-free equivalents; in practice, this often means providing a single-page layout and server-side redirects to a non-frames version when needed.
