Zulip has a growing set of conventions for how things are done visually, and it'd be good to have these written down in some form (e.g. how we do error messages, how we do realm-specific settings, etc.). I don't think this needs to be super long as a first version; once we have a thing, we can start adding new things as we go along.
Hello Tim, I'm a participante of the Outreachy Program and I would like to contribute. Can you please guide me?
Cool. A good place to start might be finishing the subscriptions page CSS split work that's partially done here: #1187.
