screenheight

Hello All,

I am working on a page with a panel that moves down to become the footer when a tab or any of the menu tabs are clicked and returns to the 'header' when the same tab or the portfolio tab is clicked. My problem is: I don't know how to make this jquery function dynamic based on the size of the users screen.  I currently have static values for testing purposes.  Any help would be appreciated. Thank you for your time.  I have included the code below.  

$(function() {
    var open = false;
    $("#footerSlideButton").click(function() {
        if(open === false) {
            $('#footerSlideContent').animate({ height: '50px' });
            $(this).css('backgroundPosition', 'bottom left');
$('#gallery').css('display','none');
            open = true;
        } else {
            $("#footerSlideContent").animate({ height: '632px' });
            $(this).css('backgroundPosition', 'top left');
$('#gallery').css('display','inline');

            open = false;
        }

    });
    $("#1,#2,#3").click(function() {
        if(open === false) {
            $('#footerSlideContent').animate({ height: '50px' });
            $(this).css('backgroundPosition', 'bottom left');
$('#gallery').css('display','none');
            open = true;
        } else {

            open = false;
        }
    });
   $("#portfolio").click(function() {
        if(open === true) {
            $('#footerSlideContent').animate({ height: '632px' });
            $(this).css('backgroundPosition', 'bottom left');
$('#gallery').css('display','inline');
            open = false;
        } else {

            open = true;
        }
    });

});
