title: What is the usage of the row class from Bootstrap?
body: <p>I think this can be a dumb question, but I don't understand the usage of the <code>.row</code> class from Twitter Bootstrap. So, what is it used for?</p>
  
  <p>I'm trying to do something like this in this structure:</p>
  
  <pre><code>LOGO
  SUB-MESSAGE
  MENU 1  | MENU 2  | MENU 3  | MENU ...
  CONTENT                                            | ADS
  CONTENT                                            | ADS
  CONTENT                                            | ADS
  CONTENT                                            | ADS
  ...                                                | ...
  </code></pre>
  
  <p>What should be a basic structure for this and where the row is needed?</p>
