Maybe it easier if I give a concrete example.
I want to hide the timeline (just as an experiment), I had a kind help from @merefield to do using CSS:
```plaintext
.topic-navigation {
display: none
}
```
For this experiment, I want to do this globally. It’s an experiment, so I don’t need to do this in the most structural / replicable / technically-correct way.
A component is not a lot of trouble. But what is even less trouble, is the `Edit CSS` setting in the default theme. I tried it and this works perfectly.
However, I want to see what my community members think, but I use the theme `zeronoise`, which does not have the `Edit CSS` setting.
My question now is, wouldn’t it be useful if Discourse had a way to tinker a bit with CSS, the way it is possible if you set the theme `Default`.
To be clear, I understand there is a usecase for `Edit CSS` that is theme specific, so it would be _in addition to_ the `Edit CSS` in `Default`, not _instead of_.
I hope that explains a bit what I’m trying to get at. Let me know if I got any technical elements wrong and I will edit accordingly.
And thanks all of sharing your thoughts. 🙏
