We need to use a descendant selector to set "hover" on the <a> element to achieve the rollover effect. This is done by adding a new background image and changing the color to white.
#navigation ul li a:hover
{
color: #fff;
background-color: #ccc;
background-image: url(nav_base2.jpg);
background-repeat: repeat-y;
}
