Oops, sorry for the invalid selector, so the right would be: $("div
span[offsetWidth!=0]");
(By the way, I've tested with > and it was working, I don' know why)
So, I've just tested this offset selector at IE6, IE7, FF3.0, Opera 9
and Chrome. And it works as expected.
Thanks a lot John, and I'm already creating a ticked as you asked.
