Update complex-flexbox.html

[stefsulzer]

Wrapping behavior of the buttons will now visually match the photograph finished example.

Changed line 58 button's flex value to 1 auto. Equivalent to flex: auto but continues above explicit usage of flex-grow/flex-shrink.

I think flex: 1 is correct here - which would set flex-basis to 0, giving equally sized items. Although I didn't build the example.

I think it would be a good idea not to change the text on the page until the PR has been discussed and merged though as now this is inconsistent.

I think I'd prefer to keep this as flex: 1 — I don't think adding auto makes much difference in this case, and in addition it adds the need to explain what auto is doing in this context. I don't think it gains us much, and it adds some possibility of confusion.

Ah, wait. I just read your revision message on MDN about this making it work in Saf/Chrome. I'm doing a U turn; PR merged ;-)

Thanks for helping out with this.
