amis 中有大量的功能类 class 可以使用，即可以用在 schema 中，也可以用在自定义组件开发中，掌握这些 class, 几乎可以不用写样式。

<div class="bg-pink-500 text-light shadow p-4 rounded-md hover:bg-pink-600">
  <div class="text-lg b-b p-b-sm">注意</div>
  <div class="p-t-xs">CSS辅助类样式做了全新的升级，请点击顶部的「样式」查看新版。旧版本可以继续，但将不再更新。</div>
</div>

## 基本使用

例如，下面这个例子，我们内容区渲染了两个按钮，但是可以看到，两个按钮紧贴在一起，并不是很美观，于是我们想添加一定的间隔

```schema: scope="body"
[
  {
    "type": "button",
    "label": "按钮1",
    "actionType": "dialog",
    "dialog": {
      "title": "弹框",
      "body": "Hello World!"
    }
  },
  {
    "type": "button",
    "label": "按钮2",
    "actionType": "dialog",
    "dialog": {
      "title": "弹框",
      "body": "Hello World!"
    }
  }
]
```

1. 通过查阅按钮文档可知，按钮支持 className 配置项，也就是说可以在按钮上添加 CSS 类名；
2. 再查阅当前页面下面 [外边距部分](#%E5%A4%96%E8%BE%B9%E8%B7%9D) 可知，我们可以添加`m-l`类名实现`margin-left: 15px;`的 CSS 效果
3. 于是我们在`按钮2`的配置中添加`"className": "m-l"`，就能实现间距效果了

```schema: scope="body"
[
  {
    "type": "button",
    "label": "按钮1",
    "actionType": "dialog",
    "dialog": {
      "title": "弹框",
      "body": "Hello World!"
    }
  },
  {
    "type": "button",
    "label": "按钮2",
    "className": "m-l",
    "actionType": "dialog",
    "dialog": {
      "title": "弹框",
      "body": "Hello World!"
    }
  }
]
```

绝大部分组件都支持各种形式的 CSS 类名自定义，然后搭配该文档中的各种类名可以实现各式各样的样式调整。具体请查阅组件文档；

## 图标

amis 集成了 [fontawesome](http://fontawesome.io/icons/)，所以关于图标部分，请前往 [fontawesome](http://fontawesome.io/icons/) 查看。

## 布局

水平布局可以考虑用 Bootstrap 的 [Grids](http://getbootstrap.com/css/#grid) 或者用 `hobx` 加 `col`

```html
<div class="hbox b-a">
  <div class="col wrapper-sm bg-success">Col A</div>
  <div class="col wrapper-sm bg-info">Col B</div>
  <div class="col wrapper-sm bg-danger">Col C</div>
</div>
```

## 宽高

```css
.w-1x {
  width: 1em;
}
.w-2x {
  width: 2em;
}
.w-3x {
  width: 3em;
}
.w-xxs {
  width: 60px;
}
.w-xs {
  width: 90px;
}
.w-sm {
  width: 150px;
}
.w {
  width: 200px;
}
.w-md {
  width: 240px;

}
.h-auto {

```

```html
