@OSUblake Thanks for the revision!
The deltaX and deltaY properties definitely simplified things a bit. I like your code, as it does use the actual handles in the div and can easily apply bounds. Wish I would have come across your version first. I ended up sticking with Sahil's code however, as I had already built out a complex application with it.
So did not use the Draggable bounds and just put in some math in the update function to calculate when the sides hit the edges of my container. Thanks!
