I was trying to run the Connected List example on this page: jQuery UI #Connected Lists
But when I copy the html and the style.css file into a local directory and open up the html, I don't get the highlight color and border as seen in the picture
In the html code, the first column has the class "ui-state-default" and the second column is "ui-state-highlight"
The drag-and-drop functionality is still all there, just not the styling.
Is there some initialization of the demo environment that isn't included in the supplied code?
