I've seen spam with this: <font style="font-size: 0;">
That's not valid html with any number, is it?
0 by itself is valid, since it doesn't matter what the units are. (0 pixels, 0 points, 0% - they're all zero.) Any other number should have some unit attached. And a style attribute can be attached to (I think) any tag.
