title: HTML/CSS lists column sorting
body: <p>i have a little problem in sorting LI tags when i'm using <em>column</em> function.
  By default it is sorting normally but i had to use columns in CSS and after that my list is like this:</p>
  
  <p>1 - 6<br>
  2 - 7<br>
  3 - 8<br>
  4 - 9<br>
  5 - 10<br></p>
  
  <p>but i need something like this:</p>
  
  <p>1 - 2<br>
  3 - 4<br>
  5 - 6<br>
  7 - 8<br>
  9 - 10<br></p>
  
  <p>here is my code: <a href="http://bit.ly/1gX6fzf" rel="nofollow">jsfiddle</a></p>
