For some reason I thought that Xenforo automatically converted css to all vendor versions, but I've just been working with some css and it only works if I use the vendor prefix, do we need to use them all the time?
Ahh yes, I guess it's only certain properties then as as that's worked for me for things like border-radius in the past, but it doesn't seem to work when I use transition property, I think it's the first time I've had to use the prefixes.
I can't see the sense why they feel the need to use vendor prefixes for experimental features, but what can you do.... I know some CSS3 stuff are fully supported through the W3C standard by most browsers now, but there are still stuff that requires vendor prefixes. Border radius, box-shadow and text shadow I don't think requires vendor prefixes anymore, but until CSS3 is officially supported the recommended way is to use vendor prefixes..
