A tip for those with CSS3 and/or vendor errors

You make a great point about vendor prefixes, but I can't blame browser vendors for implementing features faster than they are standardized. It's certainly better than being the other way around. I have faith for now that the scenario you point out will never happen.

Also, non-standard code also led to some useful technologies like AJAX. The blink and marquee tags just tell one side of the story. Just pointing that out.

I care about standards as much as anyone and I understand FIRST's intention, but I think it makes sense to stretch the rules a bit.

I guess my other point is that increasing browser support via vendor extensions (i.e. prefixed versions) isn't invalid CSS. If I remember correctly, it's actually stated in the CSS3 spec that vendor extensions are valid.

And that's true, about AJAX, although isn't that pretty standardized now (despite the fact that all browsers use a different way of doing it... again, an annoyance, much like a "new feature" done during the browser war.)

I agree. I just don't think vendor extensions are stretching the rules, haha.

And a link for the spec stating that vendor extensions are valid. (Even in CSS Level 2.1, no less.)
