How do you select the last child element in a known div where the child element is an unknown element. i.e: the element can be a paragraph or un-ordered list.
Most occasions the structure will be:
<div id="container">
<p>Text</p>
</div>
but on other occasions, the structure will be:
<div id="container">
<p>Text</p>
<ul>
<li>More Text</li>
</ul>
</div>
