Hi Alex,
at this moment, I only need to get 2-3 colors in final CSS file. But next I
think we should have a similar theme but with gradientes, that will mean
4-6 colors.
But as I go with this maybe I could need something more, but right now
don't know what could be.
As you say, the counterpart of introducing a CSS processor like SASS, is
that we introduce a new piece in the chain and that means wire it for maven
and ant.
Maybe this can be easy to do.
In order to keep our efforts controlled, I propose you the folllowing: I
can check SASS implications and maybe see in MDL what other things can be
done. If I finaly see we only need to pass colors, we can try to make the
string substitution via compiler, if not we should look to introduce SASS.
Maybe if SASS is not to hard to introduce, we should directly go with it.
what do you think?
