body: <p>I am trying to create the a dropdown  which contains some text items.When i have created dropdown and moving mouse on the options their background gets blue color and some transition effects.I think these effects are coming from bootstrap css.But i want to remove those effects and apply my effects. How should i apply my own hover effects using css .
  Follwing is my dropdown code:</p>
  
  <pre><code>&lt;div id="classifieds_div" &gt;
      &lt;div class="dropdown"&gt;
      &lt;!--Link or button to toggle dropdown --&gt;
          &lt;a  id="classifieds"  data-toggle="dropdown"
              style="" data-g-event="Maia: Header" data-g-action="Maia: Sub Header" data-g-label="Classifieds"&gt;
              &lt;center style="margin-top:8px;"&gt;&lt;big&gt;Classifieds &lt;i class="icon-chevron-down" style="font-size:20px"&gt;&lt;/i&gt;&lt;/big&gt;&lt;/center&gt; 
          &lt;/a&gt;
          &lt;ul class="dropdown-menu" id="clsfd_drdown" role="menu" aria-labelledby="dropdownMenu1"  style="position:relative;"&gt;
              &lt;li role="presentation"&gt;&lt;a class="cls" role="menuitem" tabindex="-1" href="#"&gt;Caragori 1&lt;/a&gt;&lt;/li&gt;
              &lt;li role="presentation"&gt;&lt;a class="cls" role="menuitem" tabindex="-1" href="#"&gt;Caragori 2&lt;/a&gt;&lt;/li&gt;
              &lt;li role="presentation"&gt;&lt;a class="cls" role="menuitem" tabindex="-1" href="#"&gt;Caragori 3&lt;/a&gt;&lt;/li&gt;
              &lt;li role="presentation"&gt;&lt;a class="cls" role="menuitem" tabindex="-1" href="#"&gt;Caragori 4&lt;/a&gt;&lt;/li&gt;
          &lt;/ul&gt;
      &lt;/div&gt;
  &lt;/div&gt;
