pc端页面，要做兼容。新建pc端模板时，先要初始化浏览器的样式，我命名为reset.css
@charset "utf-8";
/* 取消链接高亮 */
body,div,ul,li,ol,h1,h2,h3,h4,h5,h6,input,textarea,select,p,dl,dt,dd,a,img,button,form,table,th,tr,td,tbody,article,
aside, details,figcaption,figure,footer,header,hgroup, menu,nav,section{ -webkit-tap-highlight-color:rgba(0, 0, 0, 0); }
/* 设置HTML5元素为块 */
article, aside, details,figcaption,figure,footer,header,hgroup, menu,nav,section {display: block;}
/* 图片自适应 */
img {
max- 100%;
height: auto;
auto9; /* ie8 */
-ms-interpolation-mode:bicubic;/*为了照顾ie图片缩放失真*/
}
/* 初始化 */
body,div,ul,li,ol,h1,h2,h3,h4,h5,h6,input,textarea,select,p,dl,dt,dd,a,img,button,form,table,th,tr,td,tbody,article,
aside, details,figcaption,figure,footer,header,hgroup, menu,nav,section{margin:0; padding:0; border:none;}
*{padding: 0;margin: 0;}
body{font-family: Microsoft YaHei,Tahoma,Arial,sans-serif; color:#525252; background-color:#fff;font-size: 18px;}
em,i{font-style:normal;}
strong{font-weight: normal;}
a{text-decoration:none; color:#676767; font-family: Microsoft YaHei,Tahoma,Arial,sans-serif;}
ul,ol{list-style:none;}
h1, h2, h3, h4, h5, h6{ font-size:100%; font-family: Microsoft YaHei,Tahoma,Arial,sans-serif;;}
img{ border:none; display:block;/*img底部空白*/}
textarea{ resize:none;}
input,area{ outline:none;border:0 none; font-family: Microsoft YaHei,Tahoma,Arial,sans-serif;}/* 谷歌浏览器表单元素外框 */
table{border-collapse: collapse;}/*table的重叠边框合并*/
然后新建html页面，这里须引入jquery，其版本建议越新越好 (ps:这里是最低兼容至ie9，若想兼容更低版本，可参考我其他随笔)
<!DOCTYPE html>
<html >
<head>
<meta charset="UTF-8"/>
<title>检测IE浏览器版本是否过低</title>
<link rel="stylesheet" type="text/css" href="css/reset.css"/>
<script type="text/javascript" src="jquery-1.11.0.js"></script>
<script type="text/javascript">
/*判断浏览器版本是否过低*/
$(document).ready(function() {
var b_name = navigator.appName;
var b_version = navigator.appVersion;
var version = b_version.split(";");
var trim_version = version[1].replace(/[ ]/g, "");
if(b_name == "Microsoft Internet Explorer") {
/*如果是IE6或者IE7或者IE8*/
if(trim_version == "MSIE7.0" || trim_version == "MSIE6.0" || trim_version == "MSIE8.0") {
alert("IE浏览器版本过低，请到指定网站去下载相关版本");
//然后跳到需要连接的下载网站
//window.location.href="http://jiaoxueyun.com/download.jsp";
}
}
});
</script>
</head>
<body>
</body>
</html>
好了，基本就是这样了。
ps：欢迎拍砖
