Thank you for the information. I was using devguru.com as my
online reference and would be grateful if you could suggest
another site that is comparable in approach but which identifies
the proprietary things. Do you know of a good one?
I cannot recommend any specific online references, I take my own
approach towards finding out what features browsers support:-
P.S. Opera appears to support activeElement if Firefox does not.
If you mean - document.activeElemnet - then yes, Opera introduced it
around version 7.20, but I don't see the relevance to your original
post. If you actually meant - parentElement - then Opera has supported
that since version 5, at least while spoofing IE (and as a normal part
of the DOM in versions 7.0+), it is also available in Safari/Konqueror
and IceBrowser (at least), but while Gecko browser don't implement it
the W3C DOM - parentNode - property should be preferred (and maybe -
parentElement - used as a fall-back for pre-W3C DOM browsers resembling
IE 4).
