Switch off CSS. this will then display the layers in the order they appear
in the source. If you mean "visually" switching layers on/off, that's either
a full CSS implementation (using some nifty :hover definitions), or a
Javascript solution that sets the visibility attribute of the layer's style
definition, or switches the layer's CSS class from a visible to an hidden
one.

A classic example would be a page's navigation sidebar. Visually, you may
want it to appear on the left-hand side of the page, but it could make sense
in the source code to have the <div> after the page's main content (so that
users with text browsers, for instance, get the content first, and the
navigation later).

More and more sites are now starting to go for xhtml+css only layouts,
abandoning "visual" support for older, non-compliant browsers
(*cough*Netscape 4.x*cough*). I couldn't think of a clear leader in the
field, but http://devedge.netscape.com does a good job (although they don't
actually re-order the layers as explained above).
Hope this helps,
Patrick
