cloße, but no ßigar.
text-transform: upper; css definition is very nice. however, it's not very well supported for special cases (like the german ß ligature) by neither iexplorer nor firefox, for example:
firefox is großartig!
firefox is großartig!*
* internet explorer will display "FIREFOX IS GROßARTIG" and firefox itself will drop the last character and show "FIREFOX IS GROSSARTI"
fortunately, a simple additional space will fix the ß-tranformation at least for firefox:
firefox is großartig !
