how can I set bottom in javascript
<p>I would like to know if this is correct to set the bottom css using javascript:</p>

<pre><code>var productElement2 = document.getElementsByTagName("footer");
productElement2.style.bottom=="0"
</code></pre>

<p>I ask this because my script does not work :p.
Thanks for the feedback :). If this is correct something else might be wrong but I just want to be sure.</p>
