I have the following box shadow css on my site. It looks great in Chrome, but Firefox and IE do not recreate the effect I'm looking for. I want a white solid shadow only on the bottom of a box. How do I make this work for all browsers?

```
box-shadow: 0px 10px -14px 14px #FFF;
-webkit-box-shadow: 0px 10px -14px 14px #FFF;
-moz-box-shadow: 0px 10px -14px 14px rgb(255, 255, 255);

```
