Allow css styling of elements within custom module

[mimre25]

Hi,

I have a custom module that I would like to style via CSS.
Unfortunately, this is not possible.

I know I can style it by altering the output of the module, but that's very much in contrast to other modules, that allow styling various elements via CSS.

I looked through past issues and have seen that this is quite a common gotcha for new users and was often requested.

Is there a reason this cannot or should not be done at all?
I know it's not possible with pango, but since other modules are doing it, there must be a way.

I'd be happy to contribute code if desired 🙂
