auctionsHomeIntro currently has a video playing on the left and an image (home_sub_your_dream_house.gif). Where that item is i wish to have another div which contains a form.
At present when im adding a new div it appears only above or below, i want it inside and to the right.
Sounds like you need to play with positioning maybe. For example, you could add a <div> below the rest of your code (but still within auctionsHomeIntro), add a position: relative (and probably overflow: hidden) to auctionsHomeIntro, then add position: absolute to your new div, and position it bottom/right of the container.
