I want the east and west divs to extend down to match the height of the center div... possible?

Thanks so much.

.con{
padding-left: 22px;
padding-right: 22px;
overflow: hidden;
}

.col{
position: relative;
float: left;
}

.west{
width: 7px;
right: 22px; 
margin-left: -100%;
background: url(http://www.example.com/west.png) repeat-y;
padding: 0 0 0 15;
}

.east{
width: 7px;
margin-right: -22px;
background: url(http://www.example.com/east.png) repeat-y;
padding: 0 15 0 0;
}

.center{
width: 100%;
}
