为DUX主题添加加载中特效

首先在header.php文件<body>标签下面添加如下代码：

<div class="loading">
    <div class="loading1">
	    <div class="block"></div>
		<div class="block"></div>
		<div class="block"></div>
		<div class="block"></div>
		<div class="section-left"></div>
		<div class="section-right"></div>
    </div>
</div>

然后把下面的代码保存为load.js放在footer.php文件适当位置。

$(function(){
  setTimeout(function(){
	var load = document.getElementsByClassName('loading')[0];
 

	load.style.display = 'none';
}, 5000);

    $('.loading').css('display' , 'none');

		
});

把以下css代码保存为load.css放在header.php文件适当位置就可以了。

.loading {
    height: 100%;
    width: 100%;
    position: fixed;
    top: 0;
