Thank you for your quick reply. The only problem is that I cannot find the solution for my problem in your reply. The google window which opens in your example is stil just a window with it's own top border. It is also draggable and resizeble, which is not necessary for me. It should just be filling my screen entirely. If I make it full screen then it fills the parent window, not my entire screen. This means I have not less but even more border around my content. Or am I using your script in the wrong way?
