本文主要介紹了Vue3.0之引入Element-plus ui樣式的兩種方法，文中通過示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

第一種：CDN

目前可以通過 unpkg.com/element-plus 獲取到最新版本的資源，在頁面上引入 js 和 css 文件即可開始使用。
<! – 引入樣式 -->
< link rel=“stylesheet” href=“https://unpkg.com/element-plus/lib/theme-chalk/index.css”>
<! – 引入組件庫 -->
< script src=“https://unpkg.com/element-plus/lib/index.full.js”></ script>

<html>
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width,initial-scale=1.0" />
    <script src="https://unpkg.com/vue@next"></script>
    <!-- import CSS -->
    <link rel="stylesheet"  rel="external nofollow" >
    <!-- import JavaScript -->
    <script src="https://unpkg.com/element-plus/lib/index.full.js"></script>
    <title>Element Plus demo</title>
  </head>
  <body>
    <div id="app">
      <el-button>{{ message }}</el-button>
    </div>
    <script>
      const App = {
        data() {
          return {
            message: "Hello Element Plus",
          };
        },
      };
      const app = Vue.createApp(App);
      app.use(ElementPlus);
      app.mount("#app");
    </script>
  </body>
</html>

第二種：通過 npm 安裝，并希望配合 webpack 使用

vue-cli@4.5：新版的 vue-cli 準(zhǔn)備了相應(yīng)的 Element Plus 插件，你可以用它們快速地搭建一個(gè)基于 Element Plus 的項(xiàng)目。
引入整個(gè) Element Plus，或是根據(jù)需要僅引入部分組件。我們先介紹如何引入完整的 Element。

main.js 中寫入以下內(nèi)容：

import { createApp } from 'vue'
import ElementPlus from 'element-plus';
import 'element-plus/lib/theme-chalk/index.css';
import App from './App.vue';

const app = createApp(App)
app.use(ElementPlus)
app.mount('#app')

以上代碼便完成了 Element Plus 的引入。需要注意的是，樣式文件需要單獨(dú)引入。

之后就可以進(jìn)行樣式的按需引入使用了

<template>

 <div id="app">
      <el-button>{{ message }}</el-button>

      <el-button @click="show = !show">Click Me</el-button>

    <div style="display: flex; margin-top: 20px; height: 100px;">
      <transition name="el-fade-in-linear">
        <div v-show="show" class="transition-box">.el-fade-in-linear</div>
      </transition>
      <transition name="el-fade-in">
        <div v-show="show" class="transition-box">.el-fade-in</div>
      </transition>
    </div>
