<style type="text/css">
#dhtmltooltip{

width: 450px;
border: 1px solid black;
padding: 2px;
background-color: lightblue;
visibility: hidden;
z-index: 300;
/*Remove below line to remove shadow. Below line should always appear last within this CSS*/
filter: progidXImageTransform.Microsoft.Shadow(color=black,direction=135);
}
#dhtmlpointer{
position:absolute;
