自定义pjax动画

在外观设置界面——Pjax栏目下的自定义pjax动画的HTML结构和自定义pjax动画的CSS代码 可以不用修改代码使用自己的动画。

如果需要不仅仅是切换页面的时候，在打开博客首屏也加载动画可以参考开发者高级设置 中的first_screen_animate 的配置。

下面是自定义动画的一个举例：

该例子的 css 和 html 来自 js+css3加载动画特效代码

自定义pjax动画的HTML结构

html 结构外层要被 id 为 loading的容器包裹，外层增加 loading 的 class。内部的class 增加 preloader-inner 的 class

---

注意下面代码，第一行和最后一行是外层包裹了一个容器。

第二行中的 class 需要增加preloader-inner

<div id="loading" class="loading">
<div class="loader loaded preloader-inner">
  <div class="ball a"></div>
  <div class="ball b"></div>
  <div class="meter">
    <div class="fill" style="height: 100%;"><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1440 320">
