I have managed to create an overlay container that is instantiated off of a button press.
The overlay container's contents are another XML view.
This works pretty well but I would like to make the overlay container's background be transparent.
I set the surrounding DIV in the view to
background-color:rgba(211,211,211,0.5);
but that is not working. Anyone had any luck making an OverlayContainer with a transparent background?
