The whole fraction would be vertically centered instead of having its bar aligned relative to the text baseline, which would give mostly the same result unless the numerator and the denominator have different heights. The only issue is how to feed them with a separate stylesheet... Michel Fortin michel.fortin at michelf.com http://www.michelf.com/Received on Tuesday, 20 June 2006 06:30:58 UTC
