I cannot resist to say again that without all flex length units all this 
extremely ugly.

With flex units:

#horizontal-box { flow:horizontal;  }
#horizontal-box > * { margin-top:1fx;  }  /* children v-aligned to bottom */
#horizontal-box > * { margin:1fx 0;  }  /* children v-aligned to center */
#horizontal-box > * { margin-bottom:1fx;  /* children v-aligned to top */ }

( in some case you will need flexible margins and e.g. paddings defined
on the same element. That is what current flexbox  cannot do in principle )

If we need baseline alignment in some place then we need inline
formatting context anyway. So this:

    flow:default; /*optional declaration*/
#horizontal-box > *
   vertical-align: baseline;
will align all inline boxes to baseline and will make their widths

Just don't understand why you guys are trying to
galvanize that flexbox horse again?

I'm merging the changes that Alex and I agreed on into the Flexbox
spec right now, and I'm still not quite sure what I want to do about
flex-align.  I've got a couple of choices, which I've illustrated
here: <http://www.xanthir.com/diagrams/flex-align-diagrams.html>.
(Use Firefox - Webkit has a bug regarding box-sizing and percentage
heights on elements in table-cells that screws up the 'stretch'
diagrams, and I dunno about other browser's box-sizing support because
I don't have them on my current box.)

As you can see by the diagram, there a bunch of possibilities.  At
minimum, we should support 1, 6, 13, 14-17, and either 2, 3, or 7.
The other cases may or may not be useful; align+switch cuts out all
the other ones.

So, bikeshed time.  What seems best?  They're all roughly equal from a
spec-writing perspective.
