[code=css][/  a{
            text-decoration: none;
            color: #333333;
        }
        .bar{
            list-style: none;
            width:150px;
            height:40px;
            line-height: 40px;
            font: "Microsoft YaHei",tahoma,arial,Hiragino Sans GB,\5b8b\4f53;
            transition:all .5s cubic-bezier(0.68, -0.55, 0.265, 1.55);
            border-bottom-left-radius: 8%;
            /*border-bottom-right-radius: 5%;*/
            top:40px;
            display: none;
            position: absolute;
        }

        .bar:hover {
            height:60px;
            /*line-height: 60px;*/

        }
        #bar1{

            background: rgba(255, 106 ,106,0.5);
        }

        }

            height:40px;
            position: absolute;
            display: block;
            top:-40px;
            color:#ffffff;

.test{

手中没有easing.js，，，运行不了楼主的代码，，，不过可以给楼主一点提示。。。
jquery的动画，，，，怎么动出来，，，，就可以怎么动回去。。。。
e.g.:
拉宽：$("id").animate({width:'51px'});
缩回：$(“id”).animate({width:'0px'});
