ElementPlus 是一套为开发者、设计师和产品经理准备的基于 Vue 3.0 的组件库，提供了配套设计资源，帮助你的网站快速成型。
本次举例怎么使用：
首先安装npm install element-plus --save
然后进行全局引入，在main.js加入：

import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'

const app = createApp(App)
app.use(ElementPlus)

现在可以试一下
举个栗子

  <br />
  <el-switch v-model="value" active-text="Open" inactive-text="Close" />
  <br />
  <el-switch
    v-model="value"
    size="small"
    active-text="Open"
    inactive-text="Close"
  />
    </div>
