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。
