there are lots of initial value in the new css, why? can we provide more
specific values?

[philipj_slow, 2013/07/02 08:16:22]

I think that all instances of *: initial can be removed from this file without
ill effect, I've only added them to initially be sure that everything is
precisely the same as before my edits. Will add a cleanup commit.

[acolwell GONE FROM CHROMIUM, 2013/07/03 16:21:55]

Isn't this equivalent to 1 1 auto? I think this can be removed.

[philipj_slow, 2013/07/04 08:40:26]

It's actually equivlant to 1 1 0, tested both with getComputedStyle and
according to the spec: http://www.w3.org/TR/css3-flexbox/#flex

However, I'm not sure that the difference is intentional, I will try removing it
and looking for differences.
