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：
<!DOCTYPE html><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">
