我有个问题。我正在尝试让主题定制器根据单击的无线电输入加载不同的CSS文件，live!

目前为止，该选项在我单击“保存和发布”时保存，只有在手动重新加载整个自定义程序页面时才会加载。预览面板会在选择时刷新，但不会加载选定的CSS，我不知道是什么让Twenty Eleven这样做，但我也希望它这样说。

我已经查看了Twentyeleven主题来编写此代码。区别在于：

主题使用option 用于设置，而不是theme_mod 对于它来说，它有一些设置处理，但我认为这是针对其单独的主题选项页面，我不希望这样enqueue scripts 在普通主题的基础上添加它的“黑暗”主题，如果单击它，它实际上是实时应用的，这也是我喜欢的

如果您能帮助我了解如何在定制器预览上应用CSS，我将非常高兴。

供参考：Twentyeleven theme-options.php

这是我插件的精简版本。
