Hi, The spec for background-size has this text for when background-repeat is 'round': > If X ≠ 0 is the width of the image after step one and W is the width > of the background positioning area, then the rounded width X' = W / > round(W / X) where round() is a function that returns the nearest > natural number (integer greater than zero). What should round() do when two natural numbers are equally near? For example, with W = 250 and X = 100, should round(W / X) be 2 or 3? I suggest picking one arbitrarily (round <natural>+0.5 up or down), spec it, and add a test like one of these with 'width: 240px' (= 96*2.5) http://test.csswg.org/suites/css3-background/nightly-unstable/html4/background-repeat-round.htm http://test.csswg.org/suites/css3-background/nightly-unstable/html4/background-repeat-round-roundup.htm Alternatively, if we want to leave this undefined, mark it explicitly as such. (Though I’d prefer to avoid this.) Cheers, -- Simon Sapin
