用css美化select框

先上代码：

.selectData{
        height: 0.42rem;

        position: absolute;
        right:.28rem;
        top:.30rem;
        //去边框
        border: none;
        outline: none;
        //圆角
        -moz-border-radius:0.5rem;
        -webkit-border-radius:0.5rem;
        border-radius:0.5rem;

        background-color: #003366;
        select{
          border: none;
          outline: none;
          line-height: 0.40rem;
          //通过padding-left的值让文字居中
          padding-left:0.1rem;
          background: none;
          color: #ffffff;
         
          font-style: normal;
          font-weight:bold;
        }
        option{
          border: none;
          outline: none;
          background-color: #003366;
          color: #ffffff;
          font-weight:bold;
        }
      }
