Consider following markup:

<body> <div>On the top</div> <div>On the bottom</div> </body>

and we would like to "stick" second div to the bottom and first one to the top of the view. How would you accomplish that with XUL flexes? Probably I have missed something but that is impossible with XUL flexes.

<body style="display:box; box-orient:vertical"> <div>On the top</div> <div style="box-flex: 1"></div> <!-- maybe needs 'display: box' ? --> <div>On the bottom</div> </body>

Flexibility is really a length unit rather than some property.

No, since some layout models (traditional document layout) use one dimension as input and the other as output; you can only flex in a dimension that is input to the algorithm. In the existing CSS model, in many cases, there is no sensible height that is input to the algorithm (or, depending on how you look at it, multiple heights that might be of interest).

If flexible boxes could be said to have a flaw, it's that their use often results in extra containers (either used as springs or because of changes in alignment and orientation as you nest that necessitate the extra container). I think it might be possible to address this issue though as the spec develops (possibly borrowing concepts from the Cocoa Interface Builder spring model).

Of course many of the cases where extra containers would be needed could be implemented in other ways. For example, fixed positioning can fix something to the top and bottom of a view without the need for a separating spring.

Flexible boxes also have two implementations already and a high degree of interest from two vendors (Mozilla, Apple).
