My approach was to use float left and right to orient the div's. It was order specific so I ordered them 1,3,2 to make them appear in the same order as the comp. I used in-line block to make the elements stack next to each other, and then adjusted the padding,height and width to match the comp.//

My approach was to make the header block elements so they would stack next to each other. I gave them a bit of margin on the left for breathing room.
