DHTML可能的值

sClip String that specifies or receives one of the following values.
auto Default. Clip to expose entire object.
rect(top right bottom left) Top, right, bottom, and left specify length values, any of which can be replaced by auto, leaving that side not clipped. The value of top specifies that everything above this value on the Y axis (with 0 at the top) is clipped. The value of right specifies that everything above this value on the X axis (with 0 at the left) is clipped. The value of bottom specifies that everything below this value on the Y axis (with 0 at the top) is clipped. The value of left specifies that everything to the left of this value on the X axis (with 0 at the left) is clipped.
The property is read/write. The property has a default value of auto. The Cascading Style Sheets (CSS) attribute is not inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see about dynamic properties.

remarks

this property defines the shape and size of the positioned object that is visible. the position must be set to absolute. any part of the object that is outside the clipping region is transparent. any coordinate can be replaced by the value auto, which exposes the respective side (that is, the side is not clipped).
the order of the values clip:rect(0 0 50 50) renders the object invisible because it sets the top and right positions of the clipping region to 0. to achieve a 50-by-50 view port, use clip:rect(0 50 50 0).
the clip attribute and the clip property are available on the macintosh platform, as of microsoft® internet explorer 5.
