## 用法
|
||
|
||
结合 relative 和 absolute 定位 和位置样式 `{top|right|bottom|left|inset}-xxx`，可以很方便的实现各种组件布局。
|
||
|
||
```html
|
||
<div class="grid grid-cols-4 m:grid-cols-2 gap-4">
|
||
|
||
<!-- Span top edge -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute inset-x-0 top-0 h-16 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">1</div>
|
||
</div>
|
||
|
||
<!-- Span right edge -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute inset-y-0 right-0 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">2</div>
|
||
</div>
|
||
|
||
<!-- Span bottom edge -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute inset-x-0 bottom-0 h-16 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">3</div>
|
||
</div>
|
||
|
||
<!-- Span left edge -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute inset-y-0 left-0 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">4</div>
|
||
</div>
|
||
|
||
<!-- Fill entire parent -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute inset-0 bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">5</div>
|
||
</div>
|
||
|
||
<!-- Pin to top left corner -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute left-0 top-0 h-16 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">6</div>
|
||
</div>
|
||
|
||
<!-- Pin to top right corner -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute top-0 right-0 h-16 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">7</div>
|
||
</div>
|
||
|
||
<!-- Pin to bottom right corner -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute bottom-0 right-0 h-16 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">8</div>
|
||
</div>
|
||
|
||
<!-- Pin to bottom left corner -->
|
||
<div class="relative h-32 w-32 ... bg-blue-500">
|
||
<div class="absolute bottom-0 left-0 h-16 w-16 ... bg-red-500 text-white font-extrabold text-2xl flex items-center justify-center">9</div>
|
||
</div>
|
||
|
||
</div>
|
||
```

## 响应式设计
|
||
|
||
支持通过添加设备前缀 `m:` 或者 `pc:` 来分别针对「手机端」或者「pc端」设置样式，更多说明请前往[「响应式设计」](../../../docs/css-utilities/responsive-design.md)。
|
||
|
||
## 状态前缀
|
||
|
||
不支持[「状态前缀」](../../../docs/css-utilities/state.md)，有需求请提 [issue](https://github.com/baidu/amis/issues)。
