Thanks, I tried every combination but that one. :)

Next question: when and why do you need to add :area to be able to tag areas?

way[landuse=commercial] { fill-color: purple; }

worked. But this:

way[building=yes] { fill-color: black; }

didn't. And this:

way:area[building=yes] { fill-color: black; }

Did. ?

And finally, I have these rules:
----
way[landuse=commercial] { fill-color: purple;fill-opacity:0.5;z-index:1;}

way:area[building=yes] { fill-color:orange; z-index:4;}
----

Now, some buildings are getting rendered on top of the commercial
areas (and coming out bright orange), and some of them are being
rendered beneath the commercial areas (and coming out a dark red
colour). Bug?
