How to apply proper styles of element-plus message box?

This is how element-plus message box looks on a minimal page I built: enter image description here

I was expecting it to look like on the element-plus documentation.

I am using Vue with vite and ElementPlus. I copied the setup from vite and element plus documentation. I played with a lot other elements and they all render correctly. The minimal App.vue component which can reproduce the problem:

<template>
  <el-button text @click="open">Click to open the Message Box</el-button>
</template>

<script setup>
import { ElMessageBox } from 'element-plus'

const open = () => {
  ElMessageBox.alert('This is a message', 'Title', {
    confirmButtonText: 'OK'
  })
}
</script>

My vite.config.js

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    AutoImport({
      resolvers: [ElementPlusResolver()],
    }),
    Components({
      resolvers: [ElementPlusResolver()],
    })
  ],
  base: ''
})

The page is minimal:

<!DOCTYPE html>
<title>Vite + Vue</title>
<div id="app"></div>
<script type="module" src="/src/main.js"></script>

And so is the script:

import { createApp } from 'vue'
import App from './App.vue'
createApp(App).mount('#app')

Finally my package.json:

{
  "name": "v2",
  "private": true,
  "version": "0.0.0",
  "main": "main.js",
  "type": "module",
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "preview": "vite preview",
    "start": "electron ."
  },
  "dependencies": {
    "electron": "^20.0.2",
    "element-plus": "^2.2.12",
    "vue": "^3.2.37"
  },
  "devDependencies": {
    "@vitejs/plugin-vue": "^3.0.2",
    "unplugin-auto-import": "^0.11.1",
    "unplugin-vue-components": "^0.22.4",
    "vite": "^3.0.6"
  }
}
Solution

  • I'd say documentation does not explain it well enough https://element-plus.org/en-US/guide/quickstart.html

    When ElMessage or ElMessageBox are used their styles might need to be imported manually. The quick start / On-demand Import section does not say anything about it and all other elements work out of the box, so it is somewhat confusing.

    <template>
  <el-button text @click="open">Click to open the Message Box</el-button>
</template>

<script setup>
import { ElMessageBox } from 'element-plus';
import 'element-plus/es/components/message/style/css'; // this is only needed if the page also used ElMessage
import 'element-plus/es/components/message-box/style/css';

const open = () => {
  ElMessageBox.alert('This is a message', 'Title', {
    confirmButtonText: 'OK'
  })
}
</script>
