• JSP页面引入此CSS

•    <link href="${pageContext.request.contextpath}/style/css/style.css" type="text/css" rel="stylesheet">

• CSS代码：

.selectrJob{font:18px/29px "微软雅黑","宋体",Arial;color:#777;text-align:left;height:45px;border:2px solid #f1f1f1 !important;

    /* 清除默认的箭头样式 */
    appearance: none;
    -moz-appearance: none;
    -webkit-appearance: none;
    background:#fff url(img/select_r.png) right top no-repeat;padding:6px 70px 6px 10px}

.selectrFocus{border:2px solid #c8e6de !important;background-position:right -45px}
