They're numbers.  I've removed the 'fl' unit entirely; since I
reordered the arguments to match Alex's desired ordering, it's now
trivial to achieve what the 'fl' unit did.  Rather than saying "2fl",
you just say "flex(2)".

"Inner width" is a box-model term defined in CSS 2.1, in section 8.1.
It's synonymous with "content width".

Each distribution round details what lengths are used in it.  The
packing spaces, in particular, are used in the second distribution
round.

Hmm, I'm not sure I understand what you're confused about.  Could you
elaborate?  I'm glad to make things clearer. ^_^
