title: Bootstrap dropdown button style at focus and unfocus
body: <p>I use bootstrap and I recorded my problem <a href="https://www.youtube.com/watch?v=nTdO51F3Jkg" rel="nofollow">here</a></p>
  
  <p>When I focus button dropdown he take other background-color and at unfocus disappear border. What class from css(bootstrap.css) need to edit to put my own colors and make to don't disappear border at unfocus?</p>
  
  <pre><code>&lt;div class="collapse navbar-collapse" id="meniu"&gt;
    &lt;ul class="nav navbar-nav"&gt;
      &lt;li class="active"&gt;&lt;a href="#"&gt;&lt;b&gt;Link&lt;/b&gt;&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href="#"&gt;&lt;b&gt;Link&lt;/b&gt;&lt;/a&gt;&lt;/li&gt;
      &lt;li class="dropdown"&gt;
        &lt;a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"&gt;&lt;b&gt;Dropdown&lt;/b&gt; &lt;span class="caret"&gt;&lt;/span&gt;&lt;/a&gt;
        &lt;ul class="dropdown-menu"&gt;
          &lt;li class ="active" &gt;&lt;a href="proiecte"&gt;Proiecte&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Another action&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Something else here&lt;/a&gt;&lt;/li&gt;
          &lt;li role="separator" class="divider"&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Separated link&lt;/a&gt;&lt;/li&gt;
          &lt;li role="separator" class="divider"&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;One more separated link&lt;/a&gt;&lt;/li&gt;
        &lt;/ul&gt;
      &lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I tried to edit dropdown and dropdown-toggle but i didn't found those classes with focus(class:focus).</p>
