jquery - Css 和 Jquery 动画

Question

我要实现的是这个动画

动画链接是Material Design

我错过了什么？如何在不对元素使用 position:absolute 的情况下实现上述结果

到目前为止我做了什么

HTML:

<div class="product-list  " id="product_list">  
    <div class="item ">
        <a href="#" data-id="228">
            <div class="item-top">
                <img width="211" height="165" src="" class="et-portfolio-thumbnail img-responsive wp-post-image" alt="product66_26">                    
            </div>
            <div class="item-bottom">
                <div class="item-product-title">Unicity Activate</div>
            </div>
        </a>
    </div>

    <div class="item ">
        <a href="#" data-id="227">
            <div class="item-top">
                <img width="165" height="193" src="" class="et-portfolio-thumbnail img-responsive wp-post-image" alt="product55_24">                    
            </div>
            <div class="item-bottom">
                <div class="item-product-title">Lean Complete</div>
            </div>
        </a>
    </div>

    <div class="item ">
        <a href="#" data-id="223">
            <div class="item-top">
                <img width="245" height="215" src="" class="et-portfolio-thumbnail img-responsive wp-post-image" alt="product44_21">                    
            </div>
            <div class="item-bottom">
                <div class="item-product-title">Bios Life D</div>
            </div>
        </a>
    </div>

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, 0, 0.16);
    -webkit-transition: border-radius 500ms cubic-bezier(0.4, 0, 0.2, 1), width 500ms cubic-bezier(0.4, 0, 0.2, 1), height 500ms cubic-bezier(0.4, 0, 0.2, 1), -webkit-transform 500ms cubic-bezier(0.4, 0, 0.2, 1);
}
.item-top {
    width: 200px;
    height: 200px;
}
.item-bottom {
    padding: 8px;
    line-height: 1.5;
}

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'});
});
