Noframes

The HTML   element is part of the  syntax. As created by Netscape and implemented by other browsers, it is used to allow a regular HTML  structure to be nested in the   structure. To older browsers that do not support the  syntax, it appears that the document only contains the usual   and   structure (standard HTML behavior is to ignore tags that are not understood). Frames capable browsers will ignore  content. This element has become obsolete since HTML4.
