Hi Steiner,
I spent quite a lot of time trying to understand the issues around
nesting syntax. It looks like the CSSWG resolved to adopt "Option 3",
with representatives from all 3 engines voting in favor - and the WebKit
blog survey also resulted in "Option 3" as the top choice.
Do we know if the other engines have started work on implementation of
Option 3?
thanks,
Mike
