常规布局结构
1.一列固定宽度且居中
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
.top,
.banner,
.main,
.footer {
width: 980px;
background-color: pink;
border: 1px solid #888;
text-align: center;
margin: 0 auto;
}
.top {
height: 80px;
}
.banner {
height: 60px;
margin: 5px auto;
}
.main {
height: 400px;
}
.footer {
height: 100px;
margin: 5px auto 0;
}
</style>
</head>
<body>
<div class="top">top</div>
<div class="banner">banner</div>
<div class="main">main</div>
<div class="footer">footer</div>
</body>
</html>
2.两列左窄右宽型
左右型布局时要注意两盒子之间的浮动,盒子的宽度设置
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
.top {
width: 900px;
height: 100px;
background-color: pink;
margin: 0 auto;
}
.banner {
width: 900px;
height: 150px;
background-color: purple;
margin: 0 auto;
}
.main {
width: 900px;
height: 500px;
background-color: blue;
margin: 0 auto;
}
.left {
width: 288px;
height: 500px;
background-color: yellow;
float: left;
border: 1px solid #333;
}
.right {
width: 600px;
height: 500px;
background-color: skyblue;
float: right;
}
.footer {
width: 900px;
height: 120px;
background-color: red;
margin: 0 auto;
}
</style>
</head>
<body>
<div class="top">top</div>
<div class="banner">banner</div>
<div class="main">
<div class="left">left</div>
<div class="right">right</div>
</div>
<div class="footer">footer</div>
</body>
</html>
3.通栏平均分布型
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
* {
margin: 0;
padding: 0;
}
.top {
width: 900px;

margin: 0 auto;
}
.banner {

background-color: pink;
border: 1px solid #333;
margin: 0 auto;
}
</style>
</head>
<body>
<div class="top">top</div>
<div class="banner">
<ul>
<li class="one">1</li>
<li class="two">2</li>
<li class="three">3</li>
<li class="four">4</li>
</ul>
</div>
<div class="main">main</div>
<div class="footer">footer</div>
