title: Flexbox columns, wrap order bottom to top
body: <p>Trying to build a flexbox where the ordering of the elements not only start from the bottom but the last elements keeps getting pushed. </p>
  
  <p>The ordering would work similar to this:</p>
  
  <pre><code>[3][6]
  
  [2][5]
  
  [1][4]
  </code></pre>
  
  <p>At present, new elements will appear at the bottom of the column.</p>
  
  <p>Can this even be done with flexbox?</p>
