I made a small thing, to see if it works (it does). Behold: a six line live coding thingamabob for CSS (+ some QoL features).
Single player only at the moment, but tying it in to flok or some other thingy shouldn't be too hard? I don't do JS very much.
the actual functional bits are the 💖 contenteditable attribute 💖
and the display property (because without it the CSS is display:none, so I doubt it can be edited.
white-space: pre; retains indentation and other fun things.
