From my initial look, this seems much harder than I thought due to how icon works in the CSS-only version... Maybe not, but for the time being this is blocked on the subtask.

@Daimona Would you share a link and/or a screenshot of the projected use case?

Yup, we use this component in a few places to present unlabeled information (i.e., the icon, or its accessibility text, are the label). Some example links are:

• https://meta.wikimedia.org/wiki/Special:AllEvents: the information about each event, like location and organizers
• Event pages like https://meta.wikimedia.org/wiki/Event:Central_Notice_Requester_Training, for the same event information shown in the header

On second thought, I think it would make sense to have this go through QA. @vaughnwalters There isn't much to test here: we've updated the widgets used in Special:AllEvents and in the event page registration header to use Codex. They should look exactly the same as before, except for minor spacing and colour differences that are expected. Everything else should be the same (content, icons, accessibility text).

To clarify: the widgets in question are the ones I circled in red in this hi-tech, AI-powered, quantum-computing-assisted image:

This is working as expected now. Also, I appreciate your quantum computing / MS-Paint mashup @Daimona . Quick check, I didn't see cdx-icon as a class for any of these, is that expected? If so, this is good to go to design sign off

Special:EventDetails	Special:AllEvents	Event page

I think so. According to the docs, there are no standard classes for icons. Is there some documentation page suggesting otherwise?

I'm not sure, but just inspecting the icons and looking at the example code

I'm not sure if that's standard, at least for the CSS-only version. None of the examples linked above have it, and I'd be leaning towards following those examples.
