How to change a style on drag?

How to change a style on drag?


Inside the drag: section I have tried every which way to refer to the
item being dragged, but have not been able to get it to work.
I have tried:
$(this).css
this.
this.element
I can seem to find the next() or parent() items, but not the item
being dragged.
Reason:
I am floating a bunch of divs, and I have clear:left on all the divs
floated to the far left. Ondrag I want to change that style to
clear:none, and then on 'stop' I want to change it back to clear:left
only if it is lined up to the far left(based on X pos).
Any help would be appreciated!
