Make the div goes under another
<p>I have to style the tab slider in Wordpress, so the tab navigation div happens to be on top and the the content is under, I want to switch them but I can't
, the tab-content has position: relative already because of its content.</p>

<p>Here I try</p>

<pre><code>  css
  .wrapper {
        position: relative; 
   }
  .tab-nav {
       position:absolute;
       bottom:0;
   }
</code></pre>

<p>but tab-nav goes down but stick into the tab-content. so this way does not work.</p>

<pre><code>  &lt;div class="wrapper"&gt;
     &lt;div class="tab-nav"&gt;
     &lt;/div&gt;
     &lt;div class="tab-content"&gt;
     &lt;/div&gt;
 &lt;/div&gt;
</code></pre>

<p>I want to use css to make the tab-nav is under the tab-content. its be better if we dont use "position"</p>
