title: Can't change color of opened caret?
body: <p>I'm using Bootstrap and I want to change color of caret, when it is opened.</p>
  
  <p><p>My HTML code:</p>
  
  <pre><code>          &lt;li class="dropdown"&gt;
            &lt;a href="#" class="dropdown-togle" data-toggle="dropdown"&gt;
            &lt;b&gt;Download&lt;/b&gt;
            &lt;b class="caret"&gt;&lt;/b&gt;&lt;/a&gt;
            &lt;ul class="dropdown-menu"&gt;
              &lt;li&gt;...&lt;/li&gt;
            &lt;/li&gt;
  </code></pre>
  
  <p>I tried this code:</p>
  
  <pre><code>       .dropdown  .caret .open {
      border-top: 8px solid black;
  }
  </code></pre>
  
  <p>and one more question - can I change dropdown's form ?</p>
