Safari Version : 4.0.3 (531.9.1) Other browsers tested: Chrome 4.0.213.1: Same as Safari Firefox 3.x: Same as Safari IE 6/7: Different to Safari IE 6: Different to Safari What steps will reproduce the problem? 1. Launch the testcase file attached What is the expected result? The inner div is absolutely positioned div without left/top specified. So according to W3C standard, its left side should be at the place as same as static positioned div. W3C standard: http://www.w3.org/TR/CSS2/visudet.html#abs-non-replaced-width "2. 'left' and 'right' are 'auto' and 'width' is not 'auto', then if the 'direction' property of the element establishing the static-position containing block is 'ltr' set 'left' to the static position, otherwise set 'right' to the static position. Then solve for 'left' (if 'direction is 'rtl') or 'right' (if 'direction' is 'ltr')." What happens instead? The inner div always align to left of the outer div, which is different from the static flow. ( The first and third groups in testcase are absolutely positioned while the second and fourth groups are static positioned for comparing. ) 150377 1 hanrui.gao 2009-09-27 04:47:29 -0700 Also reported to Chromium bug system: http://code.google.com/p/chromium/issues/detail?id=23202 150437 2 mitz 2009-09-27 17:11:37 -0700 *** This bug has been marked as a duplicate of bug 19124 *** 40190 2009-09-27 04:42:25 -0700 2009-09-27 04:42:25 -0700 Testcase shows the behaviour of absolutely positioned element is not complied with W3C standard. testcase_of_text_align_center_position_absolute_standard.html text/html 689 hanrui.gao PCFET0NUWVBFIGh0bWw+DQo8c3R5bGU+DQogICAgLm91dGVyIHsNCiAgICAgICAgd2lkdGg6IDUw MHB4Ow0KICAgICAgICBoZWlnaHQ6IDIwMHB4Ow0KICAgICAgICBib3JkZXI6IDFweCBzb2xpZCBy ZWQ7DQogICAgfQ0KICAgIA0KICAgIC5pbm5lciB7DQogICAgCWJhY2tncm91bmQtY29sb3I6IGdy YXk7DQogICAgICAgIHdpZHRoOiAyMDBweDsNCiAgICAgICAgaGVpZ2h0OiAxMDBweDsNCiAgICB9 DQoJDQo8L3N0eWxlPg0KDQo8ZGl2IGNsYXNzPSJvdXRlciIgYWxpZ249InJpZ2h0Ij4NCiAgICA8 ZGl2IGNsYXNzPSJpbm5lciIgc3R5bGU9InBvc2l0aW9uOiBhYnNvbHV0ZTsiPmFsaWduPXJpZ2h0 OyBwb3NpdGlvbj1hYnNvbHV0ZTwvZGl2Pg0KPC9kaXY+DQoNCjxkaXYgY2xhc3M9Im91dGVyIiBh bGlnbj0icmlnaHQiPg0KICAgIDxkaXYgY2xhc3M9ImlubmVyIj5hbGlnbj1yaWdodDwvZGl2Pg0K PC9kaXY+DQoNCjxkaXYgY2xhc3M9Im91dGVyIiBhbGlnbj0iY2VudGVyIj4NCiAgICA8ZGl2IGNs YXNzPSJpbm5lciIgc3R5bGU9InBvc2l0aW9uOiBhYnNvbHV0ZTsiPmFsaWduPWNlbnRlcjsgcG9z aXRpb249YWJzb2x1dGU8L2Rpdj4NCjwvZGl2Pg0KDQo8ZGl2IGNsYXNzPSJvdXRlciIgYWxpZ249 ImNlbnRlciI+DQogICAgPGRpdiBjbGFzcz0iaW5uZXIiPmFsaWduPWNlbnRlcjwvZGl2Pg0KPC9k aXY+DQo=
