add "box" and "inline-box" without vendor perfixed of "display"

[BenzLeung]

Found "-webkit-box" and "-moz-box", but no "box". The same to "inline-box".

Which browsers implemented the non-prefixed values?

display: box; is a version of 2009.
display: flexbox; is a version of 2011.
display: flex; is the actual version.

Yes, that's why I asked the question. Since it's part of the 2009 version of the flexbox spec, I couldn't find documentation of any browsers which actually implemented the non-prefixed values.

Paul Irish said: The old standard (Flexbox 2009) was implemented in Chrome since v4, Firefox since v2, and IE10 beta.

I'd recommend starting with this StackOverflow and going through it's links, etc.

If you look at the caniuse.com entry for flex-box, it indicates that in Chrome from versions 4 through 21 and Firefox versions 2 through 21 (all inclusive), yes, the old standard was implemented, but it was vendor-prefixed.
