Use absolute positioning. Set the bottom: property instead of top:

Have you parent div be position: relative and the child div be position: absolute. From there, it's pretty simple.

.parent
{
    position: relative;
}

.child
{
    position: absolute;
    bottom: 0px;
    left: 0px;
    right: 0px;
    height: 20px; /*or whatever you want the height to be*/
    display: block;
}
