In MobileFrontend we are in a transitional state.
We currently use a selector in the form .mw-ui-icon-{name}:before to style an icon.
I switched our icons over to use the module [1] but the implementation is hacky due to names having ':before' in them.
It would be better to provide a neater way to do this so it is easier to move over in future (plus being able to do some kind of css injection like this is probably a concern)
Bartosz suggested replacing prefix with some kind of generic template.
Thoughts?
