如何自定义加载的启动画面？

Introducing Discourse Splash - A visual preloader displayed while site assets load

The splash lives in a different CSS scope, so sadly, you won’t be able to modify the CSS via themes. That said, we do have planned improvements, and I started with this one. Once the change is live on your site, the splash dots will use the colors from your current theme.

我认为 splash screen 的目的是在所有其他资源加载之前和加载期间进行加载。因此，现在如果您创建自定义 CSS 来修改它，它将仅在 splash screen 加载后加载。
