above - This attribute specifies the
name of the layer that will occur directly above the current layer
in the layer stacking order (z-order.) It overrides the default
behavior of placing new layers on top of all existing layers. Only
one of the Z-INDEX, ABOVE, or BELOW attributes can be used for a
given layer. References to layers not yet defined result in default
layer creation behavior - i.e. the new layer will be placed on top
of all existing layers.
background - This specifies a
background image to be tiled on a layer. Default behavior for a
layer is to be transparent.
below - This attribute specifies the
name of the layer that will occur directly below the current layer
in the layer stacking order (z-order.) It overrides the default
behavior of placing new layers on top of all existing layers. Only
one of the Z-INDEX, ABOVE, or BELOW attributes can be used for a
given layer. References to layers not yet defined result in default
layer creation behavior - i.e. the new layer will be placed on top
of all existing layers.
bgcolor - This specifies the
background color of the layer. Default behavior for a layer is to be
transparent.
clip - This parameter specifies the
clipping rectangle (viewable area) of the layer, which can be less
than the width and height of the content of the layer. If the CLIP
attribute is omitted, the clipping rectangle of a layer is the same
size as the HTML content of the layer. A layer will expand to
contain all of its content by default.
height - This parameters specifies
the height of the layer's content and serves as a reference
dimension for child layers.
left - This specifies the coordinate
position of the left side boundary position of the current layer in
relation to a parent layer if present. if no parent layer exists,
the value is relative to the main document window.
name - This attribute specifies the
name of the layer in order to identify or reference it from other
layers or scripting languages. Layers are unnamed by default.
onblur - A blur Event Handler
executes Script code when a layer loses keyboard focus.
onfocus - A focus Event Handler
executes Script code when a layer receives input focus by tabbing
with the keyboard or clicking with the mouse.
onload - This attribute executes
Script code with the completion of loading of the layer.
onMouseOver - A mouseOver Event
Handler executes Script code once each time the mouse pointer moves
over a layer from outside the layer.
onMouseOut - A mouseOut Event
Handler executes Script code once each time the mouse pointer exits
from the bounds of a layer from inside the layer.
pagex - specifies the absolute
horizontal (X) coordinate position of the left boundary position of
the current layer in relation to the document window (this differs
slightly in definition from the LEFT attribute.)
pagey - This specifies the absolute
vertical (Y) coordinate position of the top boundary position of the
current layer in relation to the document window (this differs
slightly in definition from the TOP attribute.)
src - This attribute specifies the
URL of an HTML 'sub-document' to be inserted in to the layer. The
effect is similar to the IFRAME element implemented by Internet
Explorer.
top - This specifies the coordinate
position of the top boundary position of the current layer in
relation to a parent layer if present. if no parent layer exists,
the value is relative to the main document window.
visibility - specifies whether the
layer is visible or not. A layer will have the same visibility as
its parent layer by default. Even if the visibility of a layer is
set to SHOW, a layer can only be seen if there are no other visible,
solid layers stacked on top of it. For top level layers that are not
nested inside other layers, a value of INHERIT has the same effect
as SHOW since the body document is always visible.
width - This parameters specifies
the width of the layer's content. Specifically, it controls the
right margin of the layer for wrapping purposes. Some elements may
not be 'wrappable' (like images) and extend beyond the width
specified. Layer contents wrap at the right boundary of the
enclosing block by default.
z-index - This attribute allows a
layer's stacking order (z-order) to be specified in terms of an
integer. Layers with higher numbered Z-INDEX values are stacked
above those with lower ones. Positive Z-INDEX values cause the layer
to be stacked above its parent while negative values will cause the
layer to be stacked below its parent. This attribute overrides the
default behavior of placing new layers on top of all existing
layers. Only one of the Z-INDEX, ABOVE, or BELOW attributes can be
used for any given layer.
