Discussion on: Observing Style Changes 👁

Ah I see, thanks for clarifying. I think the idea could be served as a general purpose for specifying cases in which you'd expect something to change. For example, if an external stylesheet was injected into the page via a widget. That widget might present some style issues that you would need to counter or clean up.

The library could be constructed to establish rule cases to watch for, using the MutationObserver. When one of those cases rings true, it could then perform an implemented callback function.

I've found the MutationObserver an excellent tool, as long as it's used liberally on the page. I seem to run into issues when I try to use it for everything on the page. However, breaking it down into smaller cases to watch for didn't hurt performance as much.

Just some additional thoughts. I dig what you are trying to do here and appreciate the thinking going into this. Hopefully through collaboration you get what you are looking for.
