解决在IE6、7中用height来设定SELECT标签高度无效的兼容性问题

<div class="standard_select">
    <!--边框-->
    <div class="select_shelter">
        <!--遮挡默认边框-->
        <select>
            <option selected="selected">水果</option>
            <option>苹果</option>
            <option>橘子</option>
            <option>葡萄</option>
            <option>桃子</option>
        </select>
    </div>
</div>

 .standard_select{ /*边框*/
            display:inline-block;
            *display:inline;
            zoom:1;
            border:solid 1px black;
            padding:5px; /*调整此处改变select高度*/
            *padding:7px;
        }
        .select_shelter{ /*遮挡默认边框*/
            display:inline-block;
            *display:inline;
            zoom:1;
            width:100px;
            *width:98px;
            height:20px;
            overflow:hidden;
        }
        select{
            *margin:-1px;
            padding:3px;
            border:0px;/*遮挡现代浏览器的select边框*/
            width:100px;
        }
