title: jQuery and Twitter Bootstrap progress bar
body: <p>I have this code:</p>
  
  <pre><code>&lt;div class="progress"&gt;
      &lt;div class="bar" style="width: 0%;"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>What should I do, so when I click a button somewhere on the website, the width will go from 0 to 100, in a specific time, and give the effect of a loading progress bar?</p>
  
  <p>Thanks.</p>
