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;
         }
       }
