title: How to denote common class names with slight numeral changes into one - CSS shorthand?
body: <p>I'm trying Bootstrap, and came into a question, though the question is regarding CSS:</p>
  
  <pre><code>.span1,
  .span2,
  .span3,
  .span4,
  .span5,
  .span6,
  .span7,
  .span8,
  .span9,
  .span10,
  .span11,
  .span12{
      border: 1px dashed #CCC;
      }
  </code></pre>
  
  <p>To do border to all types of <code>.span#</code>, I did the CSS mentioned above. Is there any way I can denote it by:</p>
  
  <pre><code>.span1 - .span12{
      border: 1px dashed #CCC;
      }
  </code></pre>
  
  <p>Is it possible using CSS?</p>
