自从响应式设计的理念提出以来，越来越大的网站采用这种思想。各类大型网站也如雨后春笋般的涌了出来。如：小米商城，天猫等。 
至于响应式设计的概念等大家可以去百度百度，我这里就不相信讲解了。直接为大家带来源码，用Html5实现响应式的九宫格。代码如下：

 <html> <head> <title>html5响应式九宫格title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="viewport" content="width=device-width,height=device-height,inital-scale=1.0,maximum-scale=1.0,user-scalable=no;" /> <meta name="apple-mobile-web-app-capable" content="yes" /> <meta name="apple-mobile-web-app-status-bar-style" content="black" /> <meta name="format-detection" content="telephone=no" /> <meta charset="utf-8" /> <style type="text/css"> html, body { color:#222; font-family:Microsoft YaHei, Helvitica, Verdana, Tohoma, Arial, san-serif; margin:0; padding: 0; text-decoration: none; } img { border:0; } ul { list-style: none outside none; margin:0; padding: 0; } body { background-color:#eee; } body .mainmenu:after { clear: both; content: " "; display: block; } body .mainmenu li{ float:left; margin-left: 2.5%; margin-top: 2.5%; width: 30%; border-radius:3px; overflow:hidden; } body .mainmenu li a{ display:block; color:#FFF; text-align:center } body .mainmenu li a b{ display:block; height:80px; } body .mainmenu li a img{ margin: 15px auto 15px; width: 50px; height: 50px; } body .mainmenu li a span{ display:block; height:30px; line-height:30px;background-color:#FFF; color: #999; font-size:14px; } body .mainmenu li:nth-child(8n+1) {background-color:#36A1DB} body .mainmenu li:nth-child(8n+2) {background-color:#678ce1} body .mainmenu li:nth-child(8n+3) {background-color:#8c67df} body .mainmenu li:nth-child(8n+4) {background-color:#84d018} body .mainmenu li:nth-child(8n+5) {background-color:#14c760} body .mainmenu li:nth-child(8n+6) {background-color:#f3b613} body .mainmenu li:nth-child(8n+7) {background-color:#ff8a4a} body .mainmenu li:nth-child(8n+8) {background-color:#fc5366} style> head> <body> <ul class="mainmenu"> <li><a href="/" ><b><img src="images/tb01.png" />b><span>关于我们span>a>li> <li><a href="/" ><b><img src="images/tb02.png" />b><span>新闻中心span>a>li> <li><a href="/" ><b><img src="images/tb03.png" />b><span>产品展示span>a>li> <li><a href="/" ><b><img src="images/tb04.png" />b><span>成功案例span>a>li> <li><a href="/" ><b><img src="images/tb05.png" />b><span>下载中心span>a>li> <li><a href="/" ><b><img src="images/tb06.png" />b><span>团队介绍span>a>li> <li><a href="/" ><b><img src="images/tb06.png" />b><span>人才招聘span>a>li> <li><a href="/" ><b><img src="images/tb07.png" />b><span>联系我们span>a>li> <li><a href="/" ><b><img src="images/tb08.png" />b><span>在线留言span>a>li> ul> <!-- 欢迎大家关注我的博客！如有疑问,请加QQ群：135430763共同学习！ --> body> html>
