Why is this code commented out?

I am trying to get Slickgrid to do anything, but so far no good. I am trying to debug and noticed this commented out in the html

<div class="clear-block views-view-grid cols-1-wrapper">
  <div id="1" class="views-view-grid cols-1-wrapper"</div>
      <div id="1-controls" class="views-view-grid cols-1-controls"></div>
  
  
  </div>

What is it supposed to do and why is it commented out by default?
