You probably want three tests, for the following situations: <flexbox> <div /> <abspos /> text </flexbox> <flexbox> text <abspos /> <div /> </flexbox> <flexbox> <div /> text <abspos /> text <div /> </flexbox> Using 'flex-pack:justify' for all three of them to make it easier to tell what's happening.
The spec has changed and this isn't the expected behavior anymore. See http://dev.w3.org/csswg/css3-flexbox/#flex-items
