In-Depth Information
where the direction parameter measures the angle of shadow in degrees clockwise
from 0° (directly above the object), the strength parameter indicates the extent of the
shadow blurring, and the color parameter specifies the hexadecimal color value of the
shadow. For example, the style
filter: progid:DXImageTransform.Microsoft.Shadow(direction=135,
strength=10, color=#7F7F7F);
creates a gray shadow with a strength of 10 units located at a direction of 135°.
The DropShadow filter creates a solid shadow with no blurring and has the syntax
Use a direction value of 45
for shadows located in the
upper-right corner, 135 for
lower-right shadows, 225
for lower-left shadows, and
315 for upper-left shadows.
DropShadow(color= color , offX= value , offY= value )
where color once again is a hexadecimal color value, and offX and offY specify the
offset of the shadow from the object in the horizontal and vertical directions, respec-
tively. For example, the filter style
filter: progid:DXImageTransform.Microsoft.DropShadow(color=#FF0000,
offX=5, offY=10);
places a red drop shadow 5 pixels to the right and 10 pixels down from the element.
