I'm able to fade in content fine with this
Code JavaScript:
$('#burrito').animate({'opacity' : 0}, 0);
   fadeInDivs(['#burrito']);
 
 
function fadeInDivs(els) {
    e = els.pop();
    $(e).delay(750).animate({'opacity' : 1}, 1000, function(){
        if (els.length) fadeInDivs(els);
    })
}

but how do I fade out the #burrito div before the page changes?
