below is our code for the scroll to top:

$(document).ready(function(){
	var offset = 220;
    $(window).scroll(function() {
        if ($(this).scrollTop() > offset) {
            $('a#backtop').show();
        } else {
            $('a#backtop').hide();
        }
    });
	
	$('a#backtop').click(function(event) {
        event.preventDefault();
        $('html, body').animate({scrollTop: 0}, 500);
        return false;
    });
});
