+# Elevation
+
+### Intro
+The component library provides a shadow elevation effect based on the `Material`
+specification to represent the dimensionality of an element.
+
+### Install
+
+```js
+// css
+import '@varlet/ui/es/styles/elevation.css'
+// less
+import '@varlet/ui/es/styles/elevation.less'
+```
+
+### Basic Usage
+Shadows are divided into `0-24` levels, and the higher the level, the higher the altitude.
+
+```html
+<div class="var-elevation--0"></div>
+<div class="var-elevation--1"></div>
+<div class="var-elevation--2"></div>
+......
+<div class="var-elevation--24"></div>
+```

+# 海拔效果
+
+### 介绍
+组件库提供了基于 `Material` 规范的阴影海拔效果，用来表现元素的立体感。
+
+### 引入
+
+```js
+// css
+import '@varlet/ui/es/styles/elevation.css'
+// less
+import '@varlet/ui/es/styles/elevation.less'
+```
+
+### 基本使用
+阴影程度划分为 `0-24` 个等级，等级越高海拔越高。
+
+```html
+<div class="var-elevation--0"></div>
+<div class="var-elevation--1"></div>
+<div class="var-elevation--2"></div>
