title: Alert dismissing using Twitter Bootstrap is not working?
body: <p>I'm using Google Chrome. <br> 
  Using <a href="http://twitter.github.com/bootstrap" rel="noreferrer">Twitter Bootstrap</a>, I want to add a simple alert, unfortunately the <a href="http://twitter.github.com/bootstrap/components.html#alerts" rel="noreferrer">alert</a> is not dismissing when the x is pressed!</p>
  
  <p>Here's my code based on <a href="http://twitter.github.com/bootstrap/components.html#alerts" rel="noreferrer">alert</a> documentation:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
    &lt;head&gt;
      &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"&gt;&lt;/script&gt;
      &lt;!-- Bootstrap --&gt;
      &lt;link href="css/bootstrap.min.css" rel="stylesheet" media="screen"&gt;
    &lt;/head&gt;
    &lt;body&gt;    
      &lt;div class="alert"&gt;
          &lt;button type="button" class="close" data-dismiss="alert"&gt;×&lt;/button&gt;
          &lt;strong&gt;Warning!&lt;/strong&gt; Best check yo self, you're not looking too good.
      &lt;/div&gt;      
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>And I also tried:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
    &lt;html&gt;
      &lt;head&gt;
        &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"&gt;&lt;/script&gt;
        &lt;!-- Bootstrap --&gt;
        &lt;link href="css/bootstrap.min.css" rel="stylesheet" media="screen"&gt;
      &lt;/head&gt;
      &lt;body&gt;    
      &lt;div class="alert"&gt;
          &lt;a href="#" class="close" data-dismiss="alert"&gt;×&lt;/a&gt;
          &lt;strong&gt;Warning!&lt;/strong&gt; Best check yo self, you're not looking too good.
      &lt;/div&gt;      
      &lt;/body&gt;
    &lt;/html&gt;
  </code></pre>
  
  <p>What is missing to make it dismiss ?</p>
