+## 滚动组件 (`wc-scroll`)
+> 一个用来模拟替代原生的滚动条的组件。特点是
+>> 1. 更美观的滚动条样式。 
+>> 2. 滚动条宽度不占用容器的宽度。
+
+
+### 使用
+
+只需要简单的当把`wc-scroll`当容器, 再设定宽、高即可(宽、高默认继承父级容器)。

+   《短歌行》
+对酒当歌，人生几何！
+譬如朝露，去日苦多。
+慨当以慷，忧思难忘。
+何以解忧？唯有杜康。
+青青子衿，悠悠我心。
+但为君故，沉吟至今。
+呦呦鹿鸣，食野之苹。
+我有嘉宾，鼓瑟吹笙。
+明明如月，何时可掇？
+忧从中来，不可断绝。
+越陌度阡，枉用相存。
+契阔谈䜩，心念旧恩。
+月明星稀，乌鹊南飞。
+绕树三匝，何枝可依？
+山不厌高，海不厌深。
+周公吐哺，天下归心。

+|  :-:  |   :-:   |   :-:   |     -   |
+|  axis  |  String  |   `xy`   |   设定可滚动的方向, 默认`x、y轴`都可以产生滚动条, 可以指定只有`x`或`y`轴能产生滚动条  |
+|  distance  |   Number  |  1   |  触发到底/到顶的最小滚动阀值。可以设置一个你认为合理的值, 可避免轻微滚动时也会触发事件。  |
+|  lazy  |   Number  |  1000  |  为按钮设置节流防抖, 单位毫秒, 设置一个大于0的值之后, 在指定毫秒之内, 不会多次触发触底/触顶事件  |

+## 间隔组件 (`wc-space`)
+> 一个简单的flex容器, 会自动把它的子元素之间加一个间距。
+
+
+### 使用
+
+<wc-sandbox>
+  <wc-lang slot="javascript">
+import '//jscdn.ink/@bd/ui/latest/space/index.js'
+import '//jscdn.ink/@bd/ui/latest/form/index.js'

+  <wc-icon name="info"></wc-icon>
+  <span>普通节点</span>
+</wc-space>
+  </wc-lang>
+</wc-sandbox>
+
+
+### 纵向排列 & 分散对齐
+
+只需要简单设置一个属性`vertical`和`justify`即可实现。

+
+### 间隔大小
+
+通过设置`gap={size}`来调整间距。`size`可选值有`xxxl、xxl、xl、l(默认)、m、s`,对应的间距分别是`24,20,16,12,8,4`
