Set a div to be fixed from the top for the rest of the scroll.

var fixed = false;

        $(document).scroll(function() {

            if ($(this).scrollTop() >= 220) {

                if (!fixed) {

                    fixed = true;

        $('div').css({ position: 'fixed', top: 20 });                }

            } else {

                if (fixed) {

                    fixed = false;

                    $('div').css({ position: 'static' });

                }

            }

        });
