给你网站添加加载动画效果，让网站动起来

请给网页引用了jQuery库再继续

微软压缩版:

 <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-3.5.1.min.js"></script>

第一步
添加到/head前

<!-- 刷新加载动画 -->
<div id="PageLoading" style="z-index:99999999999;">
<div id="PageLoading-center">
<div id="PageLoading-center-absolute">
<div class="object" id="object_four"></div>
<div class="object" id="object_three"></div>
<div class="object" id="object_two"></div>
<div class="object" id="object_one"></div>
</div></div></div>...

第二步
复制到/body前

<!-- 刷新加载动画 -->
<script>
$(function(){ $("#PageLoading").fadeOut(530); });
</script>...
