I think people have explained this to you in several of the half dozen threads you've got going on this same topic.
yes I understand it - I'd settle for improved documentation. the existing guide suggest that extra css is the big hammer that can crack anything, and the indents/blank lines feature has no warnings about not being reversible.
I won't mention it again - promise :-)
