| ----------- | ------------------------ |
|
|||
|
|
| box-border | box-sizing: border-box; |
|
|||
|
|
| box-content | box-sizing: content-box; |
|
|||
|
|
|
|||
|
|
## 用法
|
|||
|
|
|
|||
|
|
比如这个例子：左侧是 box-border 类型，整体高宽 128px。而右侧只是内容区域是 128px + 边框(2 * 4px) + padding （2 * 16px） 一共160px。
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<div class="flex space-x-6">
|
|||
|
|
<div class="box-border h-32 w-32 p-4 border-4 border-blue-400 bg-blue-200 rounded-md">
|
|||
|
|
<div class="h-full w-full bg-red-400"></div>
|
|||
|
|
</div>
|
|||
|
|
|
|||
|
|
<div class="box-content h-32 w-32 p-4 border-4 border-blue-400 bg-blue-200 rounded-md">
|
|||
|
|
<div class="h-full w-full bg-red-400"></div>
|
|||
|
|
</div>
|
|||
|
|
</div>
|
|||
|
|
```
