静态登录页面实现

在这里插入图片描述

}
</style>

::v-deep 样式穿透深度作用选择器

直接在中编写的话只会影响当前组件内的样式，但如果去掉scoped话又会影响全局样式。我们::v-deep可以作用其他组件，修改其他组件样式

App.vue

<template><router-view/>
</template><style>
html,body,#app{height: 100%;
}
</style>

报错-sass-loader

在vue里运行报错：Failed to resolve loader: sass-loader You may need to install it.提示需要安装sass模块

在这里插入图片描述

router/index.js

import { createRouter, createWebHashHistory } from 'vue-router'const routes = [{path:'/login',name:'login',component:()=>import('../views/login')}
]const router = createRouter({history: createWebHashHistory(),routes
})export default router
