What does it mean on a answer to a question when the 3 boxes (thumbs up, thumbs down and flag) are all grey rather than colorful?
It's because your looking at your own answer, and you can't vote for or against yourself.If everyone's is grey, then it's because the answer has been closed out, but not removed yet.
That means that it is for your answer and not someone else's. If you look at mine you have the opportunity to actually give me thumbs up, down, or flag me.
I'm pretty sure that means that you posted it... at any rate, you can't use any of them.
Either you already gave a thumbs up or down or the ? Has been posted awhile ago and is no longer accepting feedback.
