How to set transition background in jQuery Mobile?

Question

During some of the page transitions (for example during the turn and flow transitions) in jQuery Mobile a blank background/page is shown during the transitions.

For reference see: http://jquerymobile.com/demos/1.1.0/docs/pages/page-transitions.html

How does one change that blank background?

EDIT: Here's a JSfiddle to illustrate what I mean: http://jsfiddle.net/4ayER/

Answer 1

I believe you can just set CSS for the body element:

body {
 background-color: blue !important;
}

EDIT: turns out it needs the !important part.
