By the way, I've posed a text-based survey on Facebook, and gotten a few fairly consistent answers. The question is: """ Quick survey for you web-designy people: The syntax for box-shadow is x-offset, then y-offset, then blur. Now, if you see "box-shadow: 0px 0px 10px gray;", how far out from the box do you expect the blurred shadow to extend? 5px? 10px? 20px? A different number dictated by some gaussian function? """ Currently I have 4 people responding. 2 have made it clear that the expect the blur length to be the amount the blur extends from the base shadow (so the total blur area is double the specified blur length). 1 isn't completely clear, but *appears* to be saying the same thing. The fourth is Sylvain, and he and I are having a confusing discussion, so I'm not sure what he actually wants. ~TJ
