jquery - CSS主题对jquery更改无效

Question

我在 jquery 中使用 css 主题时遇到了一个非常奇怪的问题。

我在网页上应用了自定义 css 主题，页面看起来很棒。现在我已经使用 jquery 执行了一些操作。就像点击一个复选框一样，其他复选框被选中，一些被禁用。

奇怪的是，页面看起来还是一样的。也就是说，选中/禁用的复选框仍然具有与 jquery 操作之前相同的图像。

我的同事告诉我，我必须在每次 jquery 操作后应用 css 类。就像每次选中/取消选中复选框一样

是这样还是我做错了什么？我的印象是，一旦安装了主题，css 就会保持一致。

有什么建议么 ...

谢谢..

编辑：

代码很广泛，但我附上了 uniform-default.css 文件和用于应用的 js 文件。如果您需要更多代码，请告诉我。

您是否在 JS 之前检查了 CSS 是否已加载？

<head>
  <!-- import css -->
  <!-- import jquery -->

<!-- JS affecting the DOM should be called after all the elements gets rendered -->
