title: repeat background
body: <p>In a two column template, how can we use background on each column repeated when height of both columns differ?</p>
  
  <p>eg, if my column 1 height is 200px (after loading some dynamic matter) and column 2 height is 500px, column 1 background is shown according to 200px height and column 2 background is shown according to 500px but i want both columns' background to be 500px. </p>
  
  <p>Note: heights may differ because of dynamic content that will be loaded.</p>
