Have an issue with box-shadow Inset bottom only

I am using box-shadow to create an inner shadow...

box-shadow: inset 0 0 10px #000000;
-moz-box-shadow:    inset 0 0 10px #000000;
-webkit-box-shadow: inset 0 0 10px #000000;

...but would like the inner shadow to come in from the bottom only. I have tried several ways of trying to make this work but can't... How would I do this with box-shadow?

Use a negative value for the fourth length which defines the spread distance. This is often overlooked, but supported by all major browsers. See this Fiddle for the result.

div {
  background: red;
  height: 100px;
  width: 200px;
  -moz-box-shadow: inset 0 -10px 10px -10px #000000;
  -webkit-box-shadow: inset 0 -10px 10px -10px #000000;
  box-shadow: inset 0 -10px 10px -10px #000000;
}
<div></div>

On top only:

-moz-box-shadow:    inset  0  10px 10px -10px grey;
-webkit-box-shadow: inset  0  10px 10px -10px grey;
 box-shadow:        inset  0  10px 10px -10px grey;

On bottom only:

-moz-box-shadow:    inset  0 -10px 10px -10px grey;
-webkit-box-shadow: inset  0 -10px 10px -10px grey;
 box-shadow:        inset  0 -10px 10px -10px grey;

On top and bottom only:

-moz-box-shadow:    inset  0  10px 10px -10px grey, 
                    inset  0 -10px 10px -10px grey;
-webkit-box-shadow: inset  0  10px 10px -10px grey, 
                    inset  0 -10px 10px -10px grey;
 box-shadow:        inset  0  10px 10px -10px grey, 
                    inset  0 -10px 10px -10px grey;

.shadow-top {
    -moz-box-shadow:    inset  0  10px 10px -10px grey;
