Flexbox reference: tweaks to illustrations maybe

[fvsch]

Hello,

I didn't have time to carefully read all the Flexbox reference at http://tympanus.net/codrops/css_reference/flexbox/, so I've mostly skimmed it, but I've noticed a few things with the illustrations:

Typos:

• order-illustration is missing a closing parenthesis.
• align-self-illustration is missing a "e" in "baseline" ("basline").

One imprecision:

• flex-grow-illustration suggests that the values for the third example are: flex-grow: 0 for the first and last item, and flex-grow: 2 for the middle item. The text after the illustration makes it clear that the first and last items have flex-grow: 1, but the illustration can be misleading. My suggestion: add another line of text before the third example, so that the label reads:

flex-grow: 1 (all)
flex-grow: 2 (on second item)

Congrats again on all the excellent work in this reference.

Thanks a lot, fixed!
