title: Bootstrap button not working (not opening when clicking)
body: <p>Below is my snippet for using Bootstrap which contains a single drop-down button. Any idea why it is not working? (when I click it just doesn't open anything). </p>
  
  <p>I saw similar posts <a href="https://stackoverflow.com/questions/18345714/bootstrap-dropdown-menu-not-working-not-dropping-down-when-clicked">here</a> and <a href="https://stackoverflow.com/questions/12458522/bootstrap-dropdown-not-working">here</a>. But none of the suggested solutions solutions solved my problem. </p>
  
  <pre><code>&lt;html&gt;

          &lt;title&gt;Bootstrap 3 &lt;/title&gt;
          &lt;link href ="css/bootstrap.css" rel = "stylesheet"&gt;
          &lt;link href ="css/bootstrap.min.css" rel = "stylesheet"&gt;
          &lt;link href ="css/bootstrap-theme.min.css" rel = "stylesheet"&gt;

          &lt;script src="js/bootstrap.min.js"&gt;&lt;/script&gt;
      &lt;/head&gt; 
      &lt;body&gt; 
  
  
          &lt;!-- Single button --&gt;
          &lt;div class="btn-group"&gt;
            &lt;button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false"&gt;
              Action &lt;span class="caret"&gt;&lt;/span&gt;
            &lt;/button&gt;
            &lt;ul class="dropdown-menu" role="menu"&gt;
              &lt;li&gt;&lt;a href="#"&gt;Action&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 class="divider"&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;Separated link&lt;/a&gt;&lt;/li&gt;
            &lt;/ul&gt;
          &lt;/div&gt;
  
  
      &lt;/body&gt;
