title: CSS: how to make a list wrap vertically?
body: <p>I have a somewhat long list and want it to "wrap" into vertical columns. Say I have a list of 10 items and I want it to be 5 items per column, the layout should be like this:</p>
  
  <pre><code>1   6
  2   7
  3   8
  4   9
  5   10
  </code></pre>
  
  <p>Is there a way to do this in CSS?</p>
