var h = getClientSize().height - 97;

function getClientSize() { 
var a = h = 0; 
if (window.innerHeight) { 
a = window.innerWidth; 
h = window.innerHeight 
} else { 
if (document.documentElement && document.documentElement.clientHeight) { 
a = document.documentElement.clientWidth; 
h = document.documentElement.clientHeight 
} else { 
a = document.body.clientWidth; 
h = document.body.clientHeight 
} 
}
