// | #myDialog_underlay { background-color:red; }

// In the case of `dijit.Dialog`, this id is based on the id of the Dialog,
// suffixed with _underlay.
// Template has two divs; outer div is used for fade-in/fade-out, and also to hold background iframe.
// Inner div has opacity specified in CSS file.
