I really need to get caught up on CSS; I didn’t even know that :last-child
was in the CSS3 draft specification, let alone that it’s supported by Mozilla. (Er, Phoenix… um, make that Firebird… oh, no, wait, Mozilla Firebird… oh, let’s just say it’s supported by Gecko and get it over with.) An unrelated trail led me to this message on Daniel Glazman’s weblog, and trying to figure out how to duplicate :last-child
by applying :nth-child()
led to the spec.
