resizeable UI

resizeable UI

ive been trying to get the resizable plugin working but cant seem to work it out. i have both the dimension and mouse plugins that are required. running the resizeable() function works as i see in the markup the divs added by the plugin but i dont see anything on the element to indicate the elemet is resizeable and also hovering over the element or clicking around to try to resize the element does nothing. do i need to have any css for it too work? it only says it needs the dimension and mouse plugins in the documentation.
