Take a look at this JSfiddle. I am trying to make the "Push this!" div move when the menu resizes/expands on hover. Is it possible to achieve this effect using only CSS?
<div id="nav">
<ul>
<li><a href=""><span>01</span> HomePage</a>
</li>
<li><a href=""><span>02</span> SubPage 1</a>
</li>
<li><a href=""><span>03</span> SubPage 2</a>
</li>
<li><a href=""><span>04</span> SubPage 3</a>
</li>
<li><a href=""><span>05</span> SubPage 4</a>
</li>
</ul>
<div id="pad">push this!</div>
