$(document).ready(function(){
    all = $("#all > *");
        all.mouseover (
            function() {
                $(".curent").animate({height:'100px'});
                $(this).animate({height:'200px'});
                all.not(this).attr("class","cel");
                $(this).attr("class","curent");
            }
        );
});
</script>
<style>
    .cel {
        background:#7D7D7D;
        height:100px;
        width:100px;
        border:1px solid black;
