1.两列布局，左侧宽度固定，右侧宽度自适应
1.1.左侧进行浮动，右侧设置margin-left
/ 1.利用浮动进行布局/
.left {
float: left;
width: 200px;
height: 200px;
background-color: cornflowerblue;
}
.right {
margin-left: 200px;
height: 200px;
background-color: bisque;
}
[/span>div class="left"
[/span>div class="right"
1.2.利用绝对定位来代替浮动
/ 2.利用绝对定位进行布局/
.wrap {
position: relative;
}
.left {
position: absolute;
top: 0;
left: 0;
width: 200px;
height: 200px;
background-color: cornflowerblue;
}
.right {
margin-left: 200px;
height: 200px;
background-color: bisque;
}
[/span>div class="wrap"
[/span>div class="left"
[/span>div class="right"
2.两列布局，右侧宽度固定，左侧宽度自适应
2.1.利用浮动进行布局
/ 1.利用浮动进行布局/
.left {
margin-right: 200px;
height: 200px;
background-color: cornflowerblue;
}
.right {
float: right;
width: 200px;
height: 200px;
background-color: bisque;
}
[/span>div class="right"
[/span>div class="left"
注：right要写在left的前面，否则会出现如下问题。然后百度了下，终于找到了如下一段话（首先要明白浮动元素只对后面元素有影响，浮动元素本身并不浮动，只是脱离文档流，后面的元素会上移而占据浮动元素的位置）
2.2.利用绝对定位进行布局
/ 2.利用绝对定位进行布局/
.wrap {
position: relative;
}
.left {
margin-right: 200px;
height: 200px;
background-color: cornflowerblue;
}
.right {
position: absolute;
top: 0;
right: 0;
width: 200px;
height: 200px;
background-color: bisque;
}
[/span>div class="wrap"
[/span>div class="left"
[/span>div class="right"
3.三列布局，中间宽度固定，两侧宽度自适应
/ 1.常规实现方式/
.wrap {
overflow: hidden;
}
.left,
.right {
width: 50%;
height: 200px;
background-color: cornflowerblue;
}
.left {
margin-left: -300px;
float: left;
}
.right {
margin-right: -300px;
float: right;
}
.center {
margin: 0 auto;
width: 600px;
height: 200px;
background-color: bisque;
}
4.三列布局，中间宽度自适应，两侧宽度固定
4.1.利用浮动实现
/ 1.浮动实现方式/
.left,
.right {
width: 300px;
height: 200px;
background-color: cornflowerblue;
}
.left {
float: left;
}
.right {
float: right;
}
.center {
margin: 0 300px;
height: 200px;
background-color: bisque;
}
[/span>div class="right"
[/span>div class="left"
[/span>div class="center"
4.2.利用绝对定位实现
/ 2.绝对定位方式实现/
.left,
.right {
position: absolute;
top: 0;
width: 300px;
height: 200px;
background-color: cornflowerblue;
}
.left {
left: 0;
}
.right {
right: 0;
}
.center {
margin: 0 300px;
height: 200px;
background-color: bisque;
}
[/span>div class="right"
[/span>div class="left"
[/span>div class="center"
5.两列，左右等高显示
.wrap {
overflow: hidden;
}
.left,
.right {
margin-bottom: -10000px;
padding-bottom: 10000px;
}
.left {
background-color: cornflowerblue;
}
.right {
float: right;
width: 400px;
background-color: bisque;
}
[/span>div class="wrap"
[/span>div class="right"
[/span>p
[/span>p
[/span>p

span style="color: rgba(0, 0, 255, 1)"]10. 是否忘记了写DTD? [/span>p
[/span>p
[/span>p
注：以上例子均是在简单的清除了默认样式的情况下进行的
* {
margin: 0;
padding: 0;
color: #fff;
}
