The minimum inner height of the browser window for the correct display of the website is 640 pixels.
Toolbar height and surround of the browser window are about 140 pixels.
Consequently, the minimum "availHeight" of the screen must be 780 pixels.
A minimum "availHeight" of the screen of NS=748 pixels, IE=741 (12 inch TFT-Display height: 768 pixel) can be tolerated.
