html代码：

css代码：

body{background-color: #d4d4d4; height: 100%; overflow: hidden;}
    .box{ width: 600px; height: auto; margin:50px auto; position: relative;
        -webkit-transform:rotate(-34deg);
        -moz-transform:rotate(-34deg);
        -0-transform:rotate(-34deg);
        transform:rotate(-34deg);
        /*transition: all 2s linear;*/
    }
    .box >div{ width: 300px; height: 300px; border-radius: 0 300px;  position: absolute; margin-top:100px; left: -38%;opacity: 0.5;/*background: #f36486;border:1px solid orange;*/
        filter:alpha(opacity=50);
        /*IE渐变设置样式*/ 
        /* 第一个参数：渐变起始位置的颜色
        第二个参数：渐变终止位置的颜色
        第三个参数：渐变的类型
        0 代表竖向渐变        1  代表横向渐变   
        filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#00ffff,endColorstr=#9fffff,grandientType=1);
