Add sliding animation to jquery insertafter and insertbefore

How to add animation moving effect to up and down sort movement.

You can check the movement by clicking on the UP and DOWN text links.

Here is my code

$(document).ready(function(){
    $('.move-up').click(function(){
        if ($(this).prev())
            $(this).parent().insertBefore($(this).parent().prev());
    });
    $('.move-down').click(function(){
        if ($(this).next())
            $(this).parent().insertAfter($(this).parent().next());
    });
});

DEMO

Maybe something like this could help you : http://jsfiddle.net/eJk3R/38/

$(document).ready(function(){
    $('.move-up').click(function(){
        if ($(this).prev()){
            var t = $(this);
            t.parent().animate({top: '-20px'}, 500, function(){
                t.parent().prev().animate({top: '20px'}, 500, function(){
                    t.parent().css('top', '0px');
                    t.parent().prev().css('top', '0px');
                    t.parent().insertBefore(t.parent().prev());
                });
            });
        }
    });
    $('.move-down').click(function(){
        if ($(this).next()){
            var t = $(this);
            t.parent().animate({top: '20px'}, 500, function(){
                t.parent().next().animate({top: '-20px'}, 500, function(){
                    t.parent().css('top', '0px');
                    t.parent().next().css('top', '0px');
                    t.parent().insertAfter(t.parent().next());
                });
            });
        }
    });
});

It's far from perfect, you'll need to clean up the code a little bit and test the presence of an element before and after a little better before fireing the animation.

I also added position: relative; to the span style.
