[dstorey]

URL: https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes Google pos: 2nd ("flexbox")

Issue:

The support note at top is outdated. Mentions:

• WebKit implementation must be prefixed with -webkit-
• Internet Explorer implements an old version of the spec, prefixed with -ms-

Fixes:

• WebKit should be something like Safari and older webkit implementations. Latest Chrome and Opera support unprefixed
• Mention only IE10 supports older version of the spec with -ms-
