Here's some information from the Opera Forums [my.opera.com]

Q.When I used Opera's 'fullscreen' mode (F11), all styles seem to be stripped or disregarded. Is this a mis-implementation? A. In full screen mode Opera uses stylesheets that refer to media "projection"

And an Opera 7 reference [designdetector.com] I found:

On some pages, pressing F11 to move to full-screen mode loses styles, including the background! This is because Opera treats fullscreen mode as having a media type "projection" not "screen". To solve the problem, make your code similar to this: <link rel="stylesheet" href="styles.css" type="text/css" media="screen, projection" />
