Layers
a
,
b
, and
c
are at the same level, with layers
a1
and
a2
nested
within
a
and
b1
,
b2
, and
b3
nested within
b
. Although the
z-index
num-
bers might, at first glance, appear to cause Netscape 4 to interleave the
various nested layers, the actual ordering of the layers, from bottom to
top, is
c
,
a
,
a1
,
a2
,
b
,
b1
,
b3
, and
b2
.
If two layers are nested within the same layer and they have the same
z-index
value, the layer defined later in the document is placed on top
of the previously defined layer.

This, of course, applies to layers inside the same containing nest only.
H.3.1.4. The background and bgcolor attributes
As with the corresponding attributes for the
<body>
tag, you can define
the background color and an image for a Netscape 4 layer with the
bg-

Note that you can control the background color (as well as many other display features) of not just
a single tag but all
<DEFANGED_layer>
tags within your document using stylesheets. See section
The
bgcolor
attribute accepts a color name or RGB triple as its value,
as defined in
Appendix G
.
If specified, Netscape sets the entire back-
ground of the layer to this color, rendering the layer opaque. This attrib-
