how to check if div is empty and make disappear?
<p>What i have is sometimes on ym page a div could be empty and it takes up empty space.
So i want to be able to hide it of make the width small if it is empty..</p>

<p>this is the html...</p>

<pre><code>&lt;div class="four columns"&gt;
        &lt;div class="inner-column" style="height:500px;overflow: auto;"&gt;            
             &lt;ul class="SubMenu"&gt;
            &lt;/ul&gt;
        &lt;/div&gt;
    &lt;/div&gt;
</code></pre>

<p>this is the jquery i am trying...</p>

<pre><code>if ($('.four columns').is(":empty")) {
            $('.four').css('width','15px');
        }
</code></pre>

<p>whats should it be?</p>
