前言
现在web上线后首次加载会很慢，要5秒以上，并且在加载的过程中界面是白屏。因此想在白屏的时候放一个加载动画
实现步骤
1.添加以下<style>标签内容到<head>标签中
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| <style> .loading { display: flex; justify-content: center; align-items: center; margin: 0; position: absolute; top: 50%; left: 50%; -ms-transform: translate(-50%, -50%); transform: translate(-50%, -50%); } .loader { border: 16px solid #f3f3f3; border-radius: 50%; border: 15px solid ; border-top: 16px solid blue; border-right: 16px solid white; border-bottom: 16px solid blue; border-left: 16px solid white; width: 120px; height: 120px; -webkit-animation: spin 2s linear infinite; animation: spin 2s linear infinite; } @-webkit-keyframes spin { 0% { -webkit-transform: rotate(0deg); } 100% { -webkit-transform: rotate(360deg); } } @keyframes spin { 0% { transform: rotate(0deg); } 100% { transform: rotate(360deg); } } </style> |
2.添加动画到界面
添加以下代码到jjs代码前面
|-----------------------------------------------------------------|
| <div class="loading"> <div class="loader"></div> </div> |
