DIV+CSS常用的Html网页布局代码
在HTML和CSS中，`DIV` 和 `CSS` 是构建网页布局的基础。通过使用 `div` 元素和 CSS 样式，可以实现各种复杂的网页布局。以下是一些常见的 HTML 网页布局代码示例：
### 1. 基本的两列布局
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Two Column Layout</title>
<style>
body {
margin: 0;
padding: 0;
font-family: Arial, sans-serif;
}
.container {
display: flex;
}
.sidebar {
width: 250px;
background-color: #f4f4f4;
padding: 20px;
}
.content {
flex: 1;
padding: 20px;
background-color: #fff;
}
</style>
</head>
<body>
<div class="container">
<div class="sidebar">
Sidebar Content
</div>
<div class="content">
Main Content Area
</div>
</div>
</body>
</html>
```
### 2. 响应式三列布局
```html
<!DOCTYPE html>
<html lang="en">

<style>
body {
margin: 0;
padding: 0;
font-family: Arial, sans-serif;
}
.container {
display: flex;
flex-wrap: wrap;
}
.column {
padding: 20px;
box-sizing: border-box;
}
.left, .right {
width: 20%;
background-color: #f4f4f4;
}
.center {
width: 60%;
background-color: #fff;
padding: 20px;
}
@media (max-width: 768px) {

width: 100%;
}
}
</style>
</head>
<body>
<div class="container">

</div>
<div class="column center">

### 3. 固定宽度的单列布局

text-align: center;
padding: 10px;
background-color: #f4f4f4;
}
main {
padding: 20px;
}
</style>
</head>
<body>
<header>
Header
</header>
<div class="container">
<main>
Main Content Area
</main>
</div>
<footer>

</footer>
</body>
</html>
```
### 4. 单列居中布局
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Single Column Centered Layout</title>
<style>
body {
margin: 0;
padding: 0;
font-family: Arial, sans-serif;
display: flex;
justify-content: center;

height: 100vh;
background-color: #f0f0f0;

.container {
background-color: #fff;
padding: 20px;
border-radius: 8px;
