Css和Jquery动画

我想要实现的是这个动画

我缺少什么？如果不使用position：absolute,我怎样才能达到上述结果

到目前为止我做了什么

HTML：

@H_301_14@

CSS

#product_list {
    right: 0;
    left: 0;
    text-align: center;
}
.product-list .item {
    display: inline-block;
    position: relative;
    border-radius: 3px;
    margin: 4px;
    overflow: hidden;
    text-align: start;
    background-color: #fff;
    box-shadow: 0 2px 10px 0 rgba(0,0.16);
    -webkit-transition: border-radius 500ms cubic-bezier(0.4,0.2,1),width 500ms cubic-bezier(0.4,height 500ms cubic-bezier(0.4,-webkit-transform 500ms cubic-bezier(0.4,1);
}
.item-top {
    width: 200px;
    height: 200px;
}
.item-bottom {
    padding: 8px;
    line-height: 1.5;
}

使用Javascript

$('.item').on('click','a',function(e){
    e.preventDefault();
    var target=$(e.currentTarget);
    var par=target.parent();
    par.css({width:par.width()+'px',height:par.height()+'px'});
    //par.css({height:'300px',width:'500px'});
    par.animate({height:'300px'},{"queue": false,"duration":500}).animate({width:'500px'},500,'linear'); par.css({transform:'translate('+0+'px,'+50+'px)scale(1.1,1.1)'});
    par.css({'transform-origin':'0,0',zIndex:'9999'});
});

    } else if (chosen == this) {

    var ph = $('.place'); var pht = ph.offset().top - margin - scroll; var phl = ph.offset().left - margin; var phw = ph.width(); var phh = ph.height();
