On the new Style Lab we show a pattern's code beneath the example. That's great, but it'd be even better if you could open that code in Codepen (or similar) and then muck about with it.

At Mozilla's docs you can do just that:

I won't get to this for a while, so if anyone else wants to investigate how to do this (a quick google didn't turn up the API syntax).
