drop shadow only bottom css3

Is there a way to drop the shadow only on the bottom?. I have a menu with 2 images next to eachother. I don't want a right shadow because it overlaps the right image. I don't like to use images for this so is there a way to drop it only on the bottom like:

box-shadow-bottom: 10px #FFF; or similar?

-moz-box-shadow: 0px 3px 3px #000;
-webkit-box-shadow: 0px 3px 3px #000;
box-shadow-bottom: 5px #000;
/* For IE 8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=180, Color='#000000')";
/* For IE 5.5 - 7 */
filter: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=180, Color='#000000');

UPDATE 4

Same like update 3 but with modern css (=less rules) so that no special positioning on the pseudo element is required.

#box {
    background-color: #3D6AA2;
    width: 160px;
    height: 90px;
    position: absolute;
    top: calc(10% - 10px);
    left: calc(50% - 80px);
}

.box-shadow:after {
    content:"";
    position:absolute;
    width:100%;
    bottom:1px;
    z-index:-1;
    transform:scale(.9);
    box-shadow: 0px 0px 8px 2px #000000;
}

<div id="box" class="box-shadow"></div>

只需使用spread参数来减小阴影：

.shadow {
  -webkit-box-shadow: 0 6px 4px -4px black;
  -moz-box-shadow: 0 6px 4px -4px black;
  box-shadow: 0 6px 4px -4px black;
}

<div class="shadow">Some content</div>

If you have a fixed color on the background, you can hide the side-shadow effect with two masking shadows having the same color of the background and blur = 0, example:

box-shadow: 
    -6px 0 white,         /*Left masking shadow*/
    6px 0 white,          /*Right masking shadow*/
    0 7px 4px -3px black; /*The real (slim) shadow*/

Note that the black shadow must be the last, and has a negative spread (-3px) in order to prevent it from extendig beyond the corners.

Here the fiddle (change the color of the masking shadows to see how it really works).
