title: How to do multiple spans twitter bootstrap without spacing between
body: <p>I'm trying to get 3 columns on a page  without any spacing between them in bootstrap</p>
  
  <p>here is what I get:</p>
  
  <p><img src="https://i.stack.imgur.com/ifM1h.jpg" alt="span fail"></p>
  
  <p>here is what I want:</p>
  
  <p><img src="https://i.stack.imgur.com/iky4E.jpg" alt="span win"></p>
  
  <p>here is the code I'm currently using:</p>
  
  <pre><code>&lt;div class="row"&gt;
      &lt;div class="span4 blue1"&gt;
          &lt;h1&gt;span4 (1)&lt;/h1&gt;
      &lt;/div&gt;
      &lt;div class="span4 blue2"&gt;
          &lt;h1&gt;span4 (2)&lt;/h1&gt;
     &lt;/div&gt;
      &lt;div class="span4 blue3"&gt;
          &lt;h1&gt;span4 (3)&lt;/h1&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I'm really not sure how to achieve what I want using bootstrap - any help appreciated</p>
