How to get domain-specific user stylesheets in Epiphany

Epiphany isn’t really at the top of my browser list. I guess I should say ‘Web’ as it’s now called but a) nobody can google that and b) if you open the Gnome acitivities overview and type web you still get Firefox first (quick tip: type ‘epi’ and you’ll get it). Still, it has a nice interface that fits right into GNOME and it does come with basics amenities, like adblocking and a somewhat rudimentary user style sheet support.

Sadly, this is no Stylish replacement. You simply type rules in one after the other with no specification of where to apply them and where not to. So if you want to get rid of the #rightcolumn on site A but not the similarly named #rightcolumn on site B you’re out of luck. Well, you can of course jump through hoops, specifying site specific hierarchies and nesting.  Not exactly an nice solution. Here’s one I like better.
