flexbox and wrap property

Question

I am developing and app with phonegap. I wanted to use the flexbox to layout some buttons in my main application area.

Can somebody explain why this http://jsfiddle.

Answer 1

display: -webkit-box;

You probably meant -webkit-flex.

Answer 2

You have quite a few things not quite right here. First, you're mixing old properties with new properties (display: -webkit-box is from the 2009 draft, but -webkit-flex-flow is from the standard draft).

Second, none of the 2009 Flexbox implementations support box-lines: multiple, which is required for enabling wrapping. Sadly, nearly all mobile devices support only the 2009 draft. Firefox versions that support the modern specification currently do not support wrapping either (flex-flow and flex-wrap are supported properties, but the values pertaining to wrapping are not supported).

Third, you've got justify-content: space-around, but its 2009 counterpart is set to box-pack: center. Center is center in all drafts.

.flex-container {
  display: -ms-flexbox;
  display: -webkit-flex;
  -webkit-flex-wrap: wrap;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
  -ms-flex-line-pack: end;
  -webkit-align-content: flex-end;
  align-content: flex-end;
  -ms-flex-pack: distribute;
  -webkit-justify-content: space-around;
  justify-content: space-around;
  height: 100%;
}
@supports (flex-wrap: wrap) { /* hide from incomplete Firefox versions */
  .flex-container {
    display: flex;
  }
}

Update: Wrapping now works in Firefox as of version 28, but only when using the modern properties (not the old prefixed ones like display: -moz-box).
