响应式布局感觉很高大上,很难,但实际上只用CSS也能实现响应式布局
要用的就是CSS中的没接查询,下面就介绍一下怎么运用:
@media 类型 and (条件1) and (条件二){ css样式 } @media screen and (max-width:1024px) { body{ background-color: red; } }
@import url("css/moxie.css") all and (max-width:980px);
<link rel="stylesheet" type="text/css" href="css/moxie.css" media=“all and (max-width=980px)”/>
下面是一个简单的响应式的布局HTMl代码:
<!doctype html> <html> <head> <meta charset="utf-8"/> <title>响应式</title> <link rel="stylesheet" type="text/css" href="index.css"/> <link rel="stylesheet" type="text/css" href="index01.css" media="screen and (max-width:1024px) and (min-width:720px)"/> <link rel="stylesheet" type="text/css" href="index02.css" media="screen and (max-width:720px)"/> </head> <body> <p class="header">头部</p> <p class="main clearfix"> <p class="left">左边</p> <p class="center">中间</p> <p class="right">右边</p> </p> <p class="footer">底部</p> </body> </html>
下面是CSS样式:
*{ margin:0; padding:0; text-align:center; color:yellow; } .header{ width:100%; height:100px; background:#ccc; line-height:100px; } .main{ background:green; width:100%; } .clearfix:after{ display:block; height:0; content:""; visibility:hidden; clear:both; } .left,.center,.right{ float:left; } .left{ width:20%; background:#112993; height:300px; font-size:50px; line-height:300px; } .center{ width:60%; background:#ff0; height:400px; color:#fff; font-size:50px; line-height:400px; } .right{ width:20%; background:#f0f; height:300px; font-size:50px; line-height:300px; } .footer{ width:100%; height:50px; background:#000; line-height:50px; }
<link rel="stylesheet" type="text/css" href="index01.css" media="screen and (max-width:1024px) and (min-width:720px)"/>样式代码
.right{ float:none; width:100%; background:#f0f; clear:both; } .left{ width:30%; } .center{ width:70%; } .main{ height:800px; }
<link rel="stylesheet" type="text/css" href="index02.css" media="screen and (max-width:720px)"/>样式代码
.left,.center,.right{ float:none; width:100%; }
好了,布局就这么简单,细节的把握还靠不断地练习。
