I am trying to add a hover effect to a div inside a hyperlink using CSS, but I'm not sure how to do it. The divs in question have background images set in the CSS.
<div class="header_menu">
<div class="foa_logo"><img src="images/FOA-Logo.jpg"/></div>
<div class="address"></div>
<a href="#"><div class="home"></div></a>
<a href="#"><div class="about"> </div></a>
<a href="#"><div class="services"></div></a>
<a href="#"><div class="contact"></div></a>
</div>
