title: CSS Flexbox layout: old version (for working on old browser)
body: <p>I understand that there is 3 version of FlexBox in CSS.
  <strong>Old, Tweener and New</strong>:
  according to: <a href="http://css-tricks.com/old-flexbox-and-new-flexbox/" rel="nofollow">http://css-tricks.com/old-flexbox-and-new-flexbox/</a></p>
  
  <p>My question:
  does that versions are different?</p>
  
  <pre><code>display: webkit-box;
  
  display: box;
  </code></pre>
  
  <p>I know is the OLD syntax version but which one is older?</p>
  
  <p>And for older browser compatibility (android browser 2.3) which one do I need to use?</p>
