## 网格示例
|
|
|
|
#### 树等于列
|
|
|
|
```html
|
|
|
|
<div class="container">
|
|
<div class="row">
|
|
<div class="col-sm">
|
|
One of three columns
|
|
</div>
|
|
<div class="col-sm">
|
|
One of three columns
|
|
</div>
|
|
<div class="col-sm">
|
|
One of three columns
|
|
</div>
|
|
</div>
|
|
</div>
|
|
```
|
|
|
|
上面的示例使用我们预定义的网格类在小型，中型，大型和超大型设备上创建三个等宽列。这些列在页面中居中，父级为`.container` 。
|
|
|
|
#### 三个不平等的列
|
|
|
|
```html
|
|
|
|
<div class="row">
|
|
<div class="col-sm-3">.col-sm-3</div>
|
|
<div class="col-sm-6">.col-sm-6</div>
|
|
<div class="col-sm-3">.col-sm-3</div>
|
|
</div>
|
|
```
|
|
|
|
#### 两个不等的列
|
|
|
|
```html
|
|
|
|
<div class="row">
|
|
<div class="col-sm-4">.col-sm-4</div>
|
|
<div class="col-sm-8">.col-sm-8</div>
|
|
</div>
|
|
```
|
|
|
|
#### 两列嵌套列的两列
|
|
|
|
```html
|
|
|
|
<div class="row">
|
|
<div class="col-sm-8">
|
|
.col-sm-8
|
|
<div class="row">
|
|
<div class="col-sm-6">.col-sm-6</div>
|
|
<div class="col-sm-6">.col-sm-6</div>
|
|
</div>
|
|
</div>
|
|
<div class="col-sm-4">.col-sm-4</div>
|
|
</div>
|
|
```
|
|
|
|
#### 混合移动和桌面
|
|
|
|
\`\`\`HTML
|
|
|
|
.col-xs-7 .col-sm-6 .col-lg-8
|
|
|
|
.col-xs-5 .col-sm-6 .col-lg-4
|
|
|
|
.col-xs-6 .col-sm-8 .col-lg-10
|
|
|
|
.col-xs-6 .col-sm-4 .col-lg-2
|
|
```
|
|
#### Clear Floats
|
|
|
|
Clear floats (with the `.clearfix` class) at specific breakpoints to prevent strange wrapping with uneven content:
|
|
```
|
|
|
|
HTML
|
|
|
|
第1栏 调整浏览器窗口的大小以查看效果。
|
|
|
|
第2栏
|
|
|
|
第3栏
|
|
|
|
第4栏
|
|
```
|
|
#### Offsetting Columns
|
|
Move columns to the right using `.col-md-offset-*` classes. These classes increase the left margin of a column by * columns:
|
|
```
|
|
|
|
HTML
|
|
|
|
.col-sm-5 .col-md-6
|
|
|
|
.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0
|
|
```
|
|
#### Push And Pull - Change Column Ordering
|
|
Change the order of the grid columns with `.col-md-push-*` and `.col-md-pull-*` classes:
|
|
```
|
|
|
|
HTML
|
|
|
|
.col-sm-4 .col-sm-push-8
|
|
|
|
.col-sm-8 .col-sm-pull-4
|
|
|
|
\`\`\`
