Show a div if check box is checked and vice-versa
<p>I'm trying to find the value of a check box and then if it is checked it should show my div id as resizeable. If its not checked it should disappear. This is what I tried:</p>

<pre><code>var showheader = document.getElementById("ckbx_header").checked;

if ( showheader == checked ) {
    $("#resizeable").toggle("slide", {}, 1000) );
  };
</code></pre>
