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 {
