超炫 CSS3 旋转圆圈加载中蓝/黑特效，这款特效在很多站点里面都看到了，当然颜色可以自定义。这里就先举两个列子来说明下，大家可以随便 DIY！如对代码结构不熟悉，可以联系我来帮您美化！

首先在主题css文件中加入以下代码，任选其一。

代码-蓝色

#circle {
background-color: rgba(0,0,0,0);

border-left:5px solid rgba(0,0,0,0);
border-radius:50px;

代码添加

在 header.php 文件<body>标签后面加入下面的代码

<div id="circle"></div> <div id="circle1" ></div>

在主题footer.php文件底部</body>上面加入以下代码：

<script type="text/javascript">   
$(window).load(function() {        
$("#circle").fadeOut(500);  
$("#circle1").fadeOut(700);  
});  
</script>
