I wish to create a sticky header. Everytime that the user scrolls down AND the original header goes away, then the "sticky" header should kick in. 

I currently use this:

```
$(function(){
    // Check the initial Poistion of the Sticky Header
    var stickyHeaderTop = $('#sticky').offset().top;
    $(window).scroll(function(){
        if( $(window).scrollTop() > stickyHeaderTop ) {
            //$('#sticky').css({position: 'fixed', top: '0px', float: 'right'});
            $('#sticky').addClass("sticky");
        } else {
            $('#sticky').removeClass("sticky");
        }
    });
});

```

Although, the current one add the class "sticky" whenever a user just does a scroll, and not when the original header should be gone.

Regards
