    In CSS2, it is legal to use either approach.  CSS1 only permitted 
the first syntax ('a.class:visited') and not the second, so some 
browsers from that era might not know what to do with a pseudo-class 
that comes before the class value.  More recent browsers (or sloppily 
written browsers from the pre-CSS2 era) should handle both.
    Pseudo-elements, on the other hand, must ALWAYS come at the end of 
the selector.  So you can't write 'p:first-line em', because the 'em' 
incorrectly comes after the pseudo-element ':first-line'.
