How can I handle fading the background for modal dialog?
At
http://jqueryui.com/demos/dialog/#modal-form, there is a sample modal dialog; when you click on "Create new user", it displays a modal dialog and fades everything but the dialog.
On my work based on that, I've specified "modal: true," and the modal dialog appears and disappears appropriately, but nothing else is greyed out; the rest of the screen looks as it looked before.
Do I need to apply additional CSS or serve up an image? A brief look at the sample source code didn't make it clear what I need to be adding so that it greys out the background.
