HTML /css question

[Walalayo]

I made a class that can be applied to multiple things but they have different width's?
they all use the same class, but with different widths. so to differenciate between widths, are my only options inline styling or "classitis?" is there a smart and xhtml way to do this? answers greatly appreciated!
