According to CSS Transitions... >Name: transition-property >Value: none | <single-transition-property> [ ‘,’ <single-transition-property> ]* >(snip) ><single-transition-property> = all | <IDENT> http://dev.w3.org/csswg/css3-transitions/#transition-property On Windows 7 Home Premium SP1 64bit, Firefox Nightly 21.0a1(buildID 20130217031005) corresponds to this. But Chromium 27.0.1416.0 (183049) doesn't accept "all, <IDENT>" in transition-property property. http://jsfiddle.net/syoichi/zz4Uz/ Moreover, It seems that transition-property property and transition shorthand property can't accept "all, all", but transition shorthand property can accept "all, <IDENT>". I can't find description like ‘"all, <IDENT>" is invalid’ in the spec. I'm sorry if I'm wrong. related: https://www.w3.org/Bugs/Public/show_bug.cgi?id=14602
