Layers were not part of any established web based standard, and hence are not supported by Mozilla.

Thus, such a script would test whether the browser supports W3c.org standards, or whether it supports proprietary methods (document.all and document.layers) and thus work very well with new standards-compliant browsers, and acceptably with older non-standard compliant ones. An example of such a JavaScript navigation menu can be found at Peter-Paul Koch’s JavaScript menu website. It is also possible to use JavaScript to detect which browser is accessing a page, and thus direct the browser to the appropriate page. Thus, standards compliant content can be served to Mozilla (and other standards compliant browsers), w
