I am new to web design and and tackling this webpage layout. I have re-created this layout with photoshop and starting to style it with dreamweaver using pure css. However, I am stuck on how to give apply the appropriate div boxes without it collapsing, shifting to one side, etc.
Can someone give me some ideas on how I should stack the div and what div I should apply the absolute, relative position?

It might help to actually see the layout.
