短视频商城系统，首屏加载loading动画界面和路由跳转动画
1、首屏加载等待界面
（1）在public的index.html里面的id为app的div标签里面添加
<body>
<noscript>
<strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
</noscript>
<div id="app">
<div id="loader-wrapper">
<div id="loader"></div>
<div class="loader-section section-left"></div>
<div class="loader-section section-right"></div>
<div class="load_title">正在加载 nx-admin,请耐心等待
<br>
<span>V1.3</span>
</div>
</div>
</div>
</body>
