HTML and CSS Reference
In-Depth Information
clip
This attribute clips a layer's content to a specified rectangle. All layer content outside
that rectangle will be rendered transparent. The
clip
rectangle is defined by two
x,y
pairs
that correspond to the top
x
, left
y
, and bottom
x
, right
y
coordinate of the rectangle. The
coordinates are relative to the layer's origin point, 0,0, in its top-left corner, and might have
nothing to do with the pixel coordinates of the screen.
height
This attribute is used to set the height of the layer, either in pixels or as a percentage
of the screen or region the layer is contained within.
left
This attribute specifies, in pixels, the left offset of the layer. The offset is relative to its
parent layer, if it has one, or to the left browser margin if it does not.
name
This attribute assigns to the layer a name that can be referenced by programs in a
client-side scripting language. The
id
attribute also can be used.
overflow
This attribute specifies what should happen when the layer's content exceeds its
rendering box and clipping area. A value of
none
does not clip the content, while
clip
clips
the content to its dimensions or defined clipping area.
pagex
This attribute is used to set the horizontal pixel position of the layer relative to the
document window rather than any enclosing layer.
pagey
This attribute is used to set the vertical pixel position of the layer relative to the
document window rather than any enclosing layer.
src
This attribute specifies the URL that contains the content to be included in the layer.
Using this attribute with an empty element is a good way to preserve layouts under older
browsers.
top
This attribute specifies, in pixels, the top offset of the layer. The offset is relative to its
parent layer, if it has one, or to the top browser margin if it is not enclosed in another layer.
visibility
This attribute specifies whether a layer is hidden (
hidden
), shown (
show
), or
inherits (
inherits
) its visibility from the layer enclosing it.
width
This attribute specifies a layer's width, in pixels or as a percentage value of the
enclosing layer or browser width.
z-index
This attribute specifies a layer's stacking order relative to other layers. Position is
specified with positive integers, with
1
indicating the bottommost layer.
