网站纯CSS全屏loading特效(由中间向两边散开)

将代码放在head.php【顶部文件里】

css新建一个css文件

把以下代码放在</head>之前

<link rel="stylesheet" type="text/css" href="<?php echo TEMPLATE_URL; ?>css/loader.css">//路径为自己的css路径


以下PHP代码

<div id="loader-wrapper">
    <div id="loader"></div>
    <div class="loader-section section-left"></div>
    <div class="loader-section section-right"></div>
</div>
