kathy -
the simplest answer to your question is 'no, not really... but kind of'. css files are text files... which means that you're a simple search and replace away from anything you want.
have you tried bbedit's css tools? how was what you got different from what you wanted?
'one particular style is most useful to me' may be a true statement, but is frustratingly unhelpful for anyone wanting to help. how are we supposed to know what that is or what you want to accomplish without an example?
if it's just that you like your css params indented, you could do that with a regex or command + } (or ]).
more info, please.
