It does not in WebKit. The error is present in the r106740 nightly build of WebKit and in Chromium 16.0.912.77. Firefox displays the inner block shifted to the left as expected. The bug does not happen when changing padding-left. Attached is a test case. For your convenience I hosted it on a web server here: http://epsy.net46.net/stuff/webkit-margins-not-updating.html If your browser/window manager allows it, you can try switching to the inspector while hovering. The inner box updates to the correct position if you change the selection in the Elements tab. Another workaround I found was to also set a margin. Setting padding-left instead has no other effect than its own. 552762 1 shanestephens 2012-02-08 19:16:51 -0800 Confirmed present in Chrome 19.0.1035.0 canary 685788 2 bobby 2012-08-02 14:02:03 -0700 Just thought I'd add another live test-case for this since we're running into it: http://jsfiddle.net/YFGyp/5/ 929829 3 robert 2013-09-16 11:27:57 -0700 I can't reproduce this on trunk.
