[Zope] ZStylesheet multiple browser question

[Neil Burnett]

I am new to ZStyleSheet.

How do I create a rule which is different for, say, IE and Netscape?

E.g.

If I want a color to be red in IE and blue everywhere else (just an 
example :-) I can't do it in the same rule as attribute ids have to 
be unique, but they are also the name of the selector attribute.

Is it right to create two rules (myclass_ie and 
myclass_everythingelse) or is there a better way?

Thanks in advance

Neil
