title: Twitter Bootstrap - 2 column layout
body: <p>How can I make 2 column layout with Twitter Bootstrap?
  I use this scheme:</p>
  
  <pre><code>&lt;div class="container"&gt;         
    &lt;div class="row"&gt;
      &lt;div class="span2"&gt; 
        Red rectangle
      &lt;/div&gt;
      &lt;div class="span6"&gt;
        Blue rectangle
      &lt;/div&gt;
      &lt;div class="span6"&gt;
        Blue rectangle
      &lt;/div&gt;
      &lt;div class="span6"&gt;
        Blue rectangle
      &lt;/div&gt;
      &lt;div class="span6"&gt;
        Blue rectangle
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Which generates this layout:
  <img src="https://i.stack.imgur.com/G7hTl.png" alt="enter image description here"></p>
  
  <p>I would like to have the blue rectangles always "on the right", not left.</p>
  
  <p>What am I doing wrong?</p>
