function toggleFullScreen() {
 if ((document.fullScreenElement && document.fullScreenElement !== null) || 
 (!document.mozFullScreen && !document.webkitIsFullScreen)) {
 if (document.documentElement.requestFullScreen) { 
 document.documentElement.requestFullScreen(); 
 } else if (document.documentElement.mozRequestFullScreen) { 
 document.documentElement.mozRequestFullScreen(); 
 } else if (document.documentElement.webkitRequestFullScreen) { 
 document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT); 
 } 
 } else { 
 if (document.cancelFullScreen) { 
 document.cancelFullScreen();
