Do not use position absolute in Fluid Grid Layouts. It does not work in Responsive Web Design because APDivs are removed form the normal content flow and thus don't respond to other elements on the page.
Use default CSS positioning (static or none) along with margins, padding & floats.
/**side by side**/
#stage2 {
margin-top: 120px;
width: 50%; /**adjust width as required**/
float:left;
}
#stage3 {
margin-top: 120px;
width:50%;
float:left;
}
