The Sibling Function
<p>I would like to know what are the requirements for the sibling() function. For instance which selector will come in the parameters () if the html is as below and I am targeting the now div class and could you explain in a bit of detail which parent element or what is suppose to be in the parameters. Thanks all help is appreciated</p>

<pre><code>   $(function(){
          $(".target").click(function(){
              $(this).siblings(".a_cont").slideDown(100);
          });
   })

&lt;div class='yes'&gt;
  &lt;div class='what'&gt; 
    &lt;button class='target'&gt; &lt;/button&gt;
    &lt;div class='now'&gt; &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;div class='yes'&gt;
&lt;div class='what'&gt; 
    &lt;button class='target'&gt; &lt;/button&gt;
    &lt;div class='now'&gt; &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>
