dhtml可能的值

iOffset

Integer that specifies or receives the direction of the offset, in degrees. This can be one of the following values. 0 Top 45 Top right 90 Right 135 Bottom right 180 Bottom 225 Bottom left 270 Default. Left 315 Top left

The property is read/write. The property has a default value of 270 for all objects with the exception of shadow which has a default value of 225.

remarks

values less than 0 or greater than 360 automatically convert to values between 0 and 360. for example, a value of -45 degrees is equivalent to a value of 315 degrees.
