As for the concept of responsive design, you can go to Baidu and Baidu. I don’t believe in the explanation here. I will directly bring you the source code and use Html5 to implement the responsive nine-square grid. The code is as follows:
<!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"> 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="/static/imghwm/default1.png" data-src="images/tb01.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>关于我们</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb02.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>新闻中心</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb03.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>产品展示</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb04.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>成功案例</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb05.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>下载中心</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb06.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>团队介绍</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb06.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>人才招聘</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb07.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></b><span>联系我们</span></a></li> <li><a href="/" ><b><img src="/static/imghwm/default1.png" data-src="images/tb08.png" class="lazy" / alt="Detailed introduction to the sample code for implementing Jiugongge in Html5 responsive design (picture)" ></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>
