I think one of the main reason why I like Ruby on Rail is the fact it is a opinionated software. Unfortunately when it come to the design (css) part you don't get any guidance.
I have now spent quite some time, trying to find a good productive approach that suit me.
I should be very interested in knowing how other Ruby on Rails developers prefers to work with the design of your apps. I know many do not do any design at all but you how do please share your thoughts.
Do you use any CSS framework? Do you prototype directly in CSS or using photoshop/fireworks? Do you use CSS3 classes for FF and Safari and in that case how do you deal with the fallback for EE?
Do you have some good links to share where I can find good information about working in a productive way using CSS?
Thanks and sorry for my poor English
