       2.HTML默认元素样式和模板

@charset "utf-8";
html {
    font-size: 12px
}

body, ul, ol, dl, dd, h1, h2, h3, h4, h5, h6, figure, form, fieldset, legend, input, textarea, button, p, blockquote, th, td, pre, xmp {
    margin: 0;
    padding: 0
}

body, input, textarea, button, select, pre, xmp, tt, code, kbd, samp {
    line-height: 1.5;
    font-family: tahoma, arial, "Hiragino Sans GB", simsun, sans-serif
}

h1, h2, h3, h4, h5, h6, small, big, input, textarea, button, select {
    font-size: 100%
}

h1, h2, h3, h4, h5, h6 {
    font-family: tahoma, arial, "Hiragino Sans GB", "微软雅黑", simsun, sans-serif
}

h1, h2, h3, h4, h5, h6, b, strong {
    font-weight: normal
}

address, cite, dfn, em, i, optgroup, var {
    font-style: normal
}

table {
    border-collapse: collapse;
    border-spacing: 0;
    text-align: left
}

caption, th {
    text-align: inherit
}

ul, ol, menu {
    list-style: none
}

fieldset, img {
    border: 0
}

img, object, input, textarea, button, select {
    vertical-align: middle
}

article, aside, footer, header, section, nav, figure, figcaption, hgroup, details, menu {
    display: block
}

audio, canvas, video {
    display: inline-block;
    *display: inline;
    *zoom: 1
}

blockquote:before, blockquote:after, q:before, q:after {
    content: "\0020"
}

textarea {
    overflow: auto;
    resize: vertical
}

input, textarea, button, select, a {
    outline: 0 none;
    border: none;
}

button::-moz-focus-inner, input::-moz-focus-inner {
    padding: 0;
    border: 0
}

mark {
    background-color: transparent
}

a, ins, s, u, del {
    text-decoration: none
}

sup, sub {
    vertical-align: baseline
}

html {
    overflow-x: hidden;
    height: 100%;
    font-size: 50px;
    -webkit-tap-highlight-color: transparent;
}

body {
    font-family: Arial, "Microsoft Yahei", "Helvetica Neue", Helvetica, sans-serif;
    color: #333;
    font-size: .28em;
    line-height: 1;
    -webkit-text-size-adjust: none;
}

hr {
    height: .02rem;
    margin: .1rem 0;
    border: medium none;
    border-top: .02rem solid #cacaca;
}

a {
    color: #25a4bb;
    text-decoration: none;
}

        3.main.js里面导入样式文件

import '@/assets/styles/border.css'
import '@/assets/styles/reset.css'

 2.添加login路由

const routes = [

  {
    path: '/login',
    name: 'login',
    component: () => import('../views/Login.vue')
  }
]

• path: '/login'：指定了路由的路径为 "/login"，表示该路由匹配到的 URL 是 "/login"。
• name: 'login'：指定了路由的名称为 "login"，可以在代码中通过名称来进行路由导航。
• component: () => import('../views/Login.vue')：指定了该路由对应的组件为一个异步加载的组件。使用箭头函数和 import 动态导入组件，这样组件只会在访问该路由时才会被加载。

3.在APP.vue里面添加路由

<template>
  <router-view/>
</template>

        在 App.vue 中添加 <router-view> 是为了在根组件中显示当前路由对应的组件。这样，无论用户访问的是哪个路由，对应的组件都会被渲染到 <router-view> 中，保证了页面的动态切换和导航效果。

4.页面

<template>
  <div class="login">

    <el-form ref="loginRef" :model="loginForm" :rules="loginRules" class="login-form">
      <h3 class="title">Java1234 Vue3 后台管理系统</h3>

      <el-form-item prop="username">

        <el-input

            type="text"
            size="large"
            auto-complete="off"
            placeholder="账号"
        >

        </el-input>
      </el-form-item>
      <el-form-item prop="password">
        <el-input

            type="password"
            size="large"
            auto-complete="off"
            placeholder="密码"
            @keyup.enter="handleLogin"
        >

        </el-input>
      </el-form-item>


      <el-checkbox  style="margin:0px 0px 25px 0px;">记住密码</el-checkbox>
      <el-form-item style="width:100%;">
        <el-button
            size="large"
            type="primary"
            style="width:100%;"
            @click.prevent="handleLogin"
        >
          <span>登 录</span>

        </el-button>

      </el-form-item>
    </el-form>
    <!--  底部  -->
    <div class="el-login-footer">

在APP.vue添加全局文章来源地址https://www.toymoban.com/news/detail-538915.html

<style>
html,body,#app{
  height: 100%;
}

.app-container{
