                padding: 0;
                margin: 0;
            }
            .tubiao,.jihua,.shiji,.riqi{
                width: 100%;
                overflow: hidden;
                margin-top: 10px;
            }
            .left{
                width: 10%;
                float: left;

                height: 25px;
                line-height: 25px;
            }
            .right{
                width: 90%;
                float: right;
