前端静态登录页面实现

引入全局样式：

main.js导入样式文件：

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

加路由：

const routes = [

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

App.vue

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

安装sass和sass-loader依赖

Login.vue

<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>
