+## Built-in Style
+Vant contains some common styles that can be used directly by the className.
+
+### Text ellipsis
+When the text content length exceeds the maximum container width, the excess text is automatically omitted.
+
+```html
+<div class="van-ellipsis">
+  This is a paragraph of 250px width limit, the back will be omitted.
+</div>
+```
+
+### Hairline
+Add 1px border under the Retina screen for the element, based on a pseudo element.
+
+```html
+<!-- border top -->
+<div class="van-hairline--top"></div>
+
+<!-- border bottom -->
+<div class="van-hairline--bottom"></div>
+
+<!-- border left -->
+<div class="van-hairline--left"></div>
+
+<!-- border right -->
+<div class="van-hairline--right"></div>
+
+<!-- border top & bottom -->
+<div class="van-hairline--top-bottom"></div>
+
+<!-- full border -->
+<div class="van-hairline--surround"></div>
+```
+
+### Animation
+
+```html
+<!-- fade in  -->
+<transition name="van-fade">
+  <div v-show="visible">Fade</div>
+</transition>
+
+<!-- slide bottom -->
+<transition name="van-slide-bottom">
+  <div v-show="visible">Fade</div>
+</transition>
+```

+## 内置样式
+Vant 中默认包含了一些常用样式，可以直接通过 className 的方式使用。
+
+### 文字省略
+当文本内容长度超过容器最大宽度时，自动省略多余的文本。
+
+```html
+<div class="van-ellipsis">这是一段宽度限制 250px 的文字，后面的内容会省略</div>
+```
+
+### 1px 边框
+为元素添加 Retina 屏幕下的 1px 边框（即 hairline），基于伪类 transform 实现。
+
+```html
+<!-- 上边框 -->
+<div class="van-hairline--top"></div>
+
+<!-- 下边框 -->
+<div class="van-hairline--bottom"></div>
+
+<!-- 左边框 -->
+<div class="van-hairline--left"></div>
+
+<!-- 右边框 -->
+<div class="van-hairline--right"></div>
+
+<!-- 上下边框 -->
+<div class="van-hairline--top-bottom"></div>
+
+<!-- 全边框 -->
+<div class="van-hairline--surround"></div>
+```
+
+### 动画
+可以通过 `transition` 组件使用内置的动画
+
+```html
+<!-- 淡入 -->
+<transition name="van-fade">
+  <div v-show="visible">Fade</div>
+</transition>
+
+<!-- 下滑 -->
+<transition name="van-slide-bottom">
+  <div v-show="visible">Fade</div>
+</transition>
+```
