title: Bootstrap Fade on Tab is not working
body: <p>Here is my code         </p>
  
  <pre><code>&lt;!-- Nav tabs --&gt;
              &lt;div class="container"&gt;
  &lt;ul class="nav nav-tabs" role="tablist"&gt;
    &lt;li role="presentation" class=""&gt;&lt;a href="#tab1" role="tab" data-toggle="tab"&gt;Tab1&lt;/a&gt;&lt;/li&gt;
    &lt;li role="presentation"&gt;&lt;a href="#tab2" role="tab" data-toggle="tab"&gt;Tab2&lt;/a&gt;&lt;/li&gt;
    &lt;li role="presentation"&gt;&lt;a href="#tab3" role="tab" data-toggle="tab"&gt;Tab3&lt;/a&gt;&lt;/li&gt;
    &lt;li role="presentation"&gt;&lt;a href="#tab4" role="tab" data-toggle="tab"&gt;Tab4&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  &lt;/div&gt;
  
  &lt;!-- Tab panes --&gt;
  &lt;div class="tab-content"&gt;
    &lt;div role="tabpanel" class="tab-pane fade" id="tab1"&gt;Texts&lt;/div&gt;
    &lt;div role="tabpanel" class="tab-pane fade" id="tab2"&gt;Some text&lt;/div&gt;
    &lt;div role="tabpanel" class="tab-pane fade" id="tab3"&gt;Just fill this pace&lt;/div&gt;
    &lt;div role="tabpanel" class="tab-pane fade" id="tab4"&gt;Some more texts&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Fade is not working as I removed active ( I do not wish to any tab to be active on load so) how can I make fade in effect without using active.</p>
