纯css为select添加样式(无脚本)实现

<div class="select_style">
<select name="select">
<option>AAAAAAAAAAA</option>
<option>BBBBBBBBBBB</option>
<option selected>CCCCCCCCCCC</option>
<option>DDDDDDDDDDD</option>
</select>
</div>

.select_style {width:240px; height:30px; overflow:hidden; background:url(../images/arrow.png) no-repeat 215px;
border:1px solid #ccc;
-moz-border-radius: 5px; /* Gecko browsers */
-webkit-border-radius: 5px; /* Webkit browsers */
border-radius:5px;
}
.select_style select { padding:5px; background:transparent; width:268px; font-size: 16px; border:none; height:30px;
-webkit-appearance: none; /*for Webkit browsers*/
}
