title: Bootstrap-3 grid layout and a fixed sized ad banner
body: <p>While reading about the new grid system of bootstrap I asked myself, how do ad banners fit into such grid systems?</p>
  
  <p>I am aware of responsive ads (ad sense, etc) but I still do not understand how those concepts apply to a skyscraper ad banner properly.</p>
  
  <p>Here is a mock of what I am talking about:

  <p>Having a horizontal ad is fine but how does bootstrap help me to create such a layout?
  Hiding the skyscraper for small devices is no problem, using grid helpers, but am I right, that I still need to mess with <code>float: left;</code> and <code>clearfix</code> for such a scenario?</p>
  
  <p>Even if the skyscraper would be responsive and resize itself according to some column width, e.g <code>col-md-2</code>, etc, it still would require some sort of "row span" in order to span arbitrary rows.</p>
  
  <p><strong>Edit:</strong> just to make it clear: I am not asking for a complete markup all-dressed up, just for insights whether such a concept is outdated in responsive times or that this is still something for <code>float: right</code> or <code>position: relative</code> etc.</p>
