一.单列布局
[cce]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>一列布局</title>
<style type="text/css">
body {
margin: 0;
padding: 0;
font-size: 30px
}
div {
text-align: center;
font-weight: bold
}
.main,
.footer {
width: 960px;
}
.head {
width: 100%;
height: 100px;
background: #ccc
}
.main {
height: 600px;
background: #FCC;
margin:0 auto;
}
.footer {
height: 50px;a
background: #9CF;
margin:0 auto;
}
</style>
</head>
<body>
<div class="head">head</div>
<div class="main">main</div>
<div class="footer">footer</div>
</body>
</html>
[/cce]
二.双列布局
[cce]
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<style>
body {
margin: 0;
padding: 0;
}
.main {
width: 800px;
margin: 0 auto;
background: green;
}
.left {
width: 220px;
background: #ccc;
float: left;
height: 500px;
}
.right {
width: 580px;
background: blue;
float: right;
height: 500px;
}
</style>
<body>
<div class="main">
<div class="left"></div>
<div class="right"></div>
</div>
</body>
</html>
[/cce]
三.三列布局
1.使用float
[cce]
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<style>
body {
margin: 0;
padding: 0;
}
.left {
width: 33.33%;
height: 500px;
float: left;
background: red;
}
.middle {
width: 33.33%;
height: 500px;
float: left;
background: blue;
}
.right {
width: 33.33%;
height: 500px;
float: left;
background: green;
}
</style>
<body>
<div class="left"></div>
<div class="middle"></div>
<div class="right"></div>
</body>
</html>
[/cce]
2.使用绝对定位:
[cce]
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<style>
body {
margin: 0;
padding: 0;
}
.left {
width: 200px;
height: 500px;
background: red;
position: absolute;/*绝对定位*/
left: 0;
top: 0;
}
.middle {
height: 500px;
background: blue;
margin: 0 310px 0 210px;
}
.right {
width: 300px;
height: 500px;
background: green;
position: absolute;
right: 0;
top: 0;
}
</style>
<body>
<div class="left">200px</div>
<div class="middle">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Error quisquam incidunt excepturi. Reiciendis cumque architecto, cum explicabo illum quod tenetur aliquid facilis quibusdam mollitia eligendi. A pariatur deleniti eaque, iste.</div>
<div class="right">300px</div>
</body>
</html>
[/cce]
四.混合布局
[cce]
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<style>
body {
margin: 0;
padding: 0;
}
.top {
width: 100%;
height: 100px;
background: blue;
}
.main {
width: 800px;
height: 500px;
background: red;
margin: 0 auto;
}
.foot {
width: 800px;
height: 100px;
background: green;
margin: 0 auto;
}
.left {
width: 300px;
height: 500px;
float: left;
background: black;
}
.right {
width: 500px;
height: 500px;
float: right;
background: yellow;
}
.head {
width: 800px;
margin: 0 auto;
height: 100px;
background: red;
}
</style>
<body>
<div class="top">
<div class="head"></div>
</div>
<div class="main">
<div class="left"></div>
<div class="right"></div>
</div>
<div class="foot"></div>
</body>
</html>
[/cce]
使用相对和绝对定位混合布局:

[cce]
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
body {
margin: 0;
padding: 0;
}
.top {
width: 100%;
background: #ccc;
height: 100px;
}
.foot {
width: 100%;
background: #ff6634;
height: 50px;
}
.main {
width: 100%;
height: 500px;
background: red;
}
.left {
width: 200px;
height: 500px;
background: #0000fe;
position: absolute;
top: 100px;
left: 0;
}
.right {
height: 500px;
background: #9acc99;
position: relative;
top: 0;
right: 0;
margin-left: 210px;
}
</style>
</head>
<body>
<div class="top">top</div>
<div class="main">
<div class="right">left</div>
<div class="left">right</div>
</div>
<div class="foot">foot</div>
</body>
</html>
