extend element height by sliding (as opposed to abruptly expanding)
<p>i would like to expand the height of the box when it is clicked on. </p>

<pre><code> $(this).find("textarea").css("height","2.6em").focus();
</code></pre>

<p>The code above expands the box, but does so abruptly. </p>

<p>How can i make it do so in a sliding manner that is much more elegant?</p>
