A way to counteract or compensate this is to > create a reversed test that has the red #test being background-sized > down (from say 100px intrinsic to 60px) and then have a smaller green > square #ref (say a 60x60 green square) overlap it. > > red_box.png is 100px by 100px in > http://test.csswg.org/suites/css2.1/20110111/xhtml1/support/ > > ----------- > > > http://test.csswg.org/source/contributors/intel/submitted/css3- > background/background-size-013.html > > > http://test.csswg.org/source/contributors/intel/submitted/css3- > background/background-size-014.html > > > Just as I thought, background-size-013.html and background-size-014.html > are passed by weak and/or buggy browsers (IE7, IE8, NS6.2, Amaya 11.4.4, > Hv3 TKHTML alpha 16) when these 2 tests should fail in such browsers. > These 2 tests should be considered as tests which do not fail and can > not fail in browsers that only support CSS1. > > Zhiqiang, I believe those 2 tests should be redone in a way that these > tests display red when background-size is not scaling down the > background-image (original intrinsic height and intrinsic width) > appropriately. > > On the same test design perspective, > > http://test.csswg.org/source/contributors/intel/submitted/css3- > background/background-size-015.html > > is doing the right thing: it will display red if background-size > declaration is not applied at all or if it is not supported. There is > also a good chance that it may display red too if background-size > declaration is not applied correctly. > Agree all with you.
