CSS for Safari only?

Hi all,

I'm in the middle of modifying a web site's template and came across a CSS problem, it renders fine in FireFox and (even in) IE, but is off by about 20px in Safari...

Does anyone know if there's a way to create CSS classes that only Safari understands (or doesn't understand)?

Any help appreciated, thanks in advance ! 🙂
