Question

I created a drop down nav menu purely in css and everything works correctly except the hover effects. When I high light one of the options in the horizontal menu it will show a red background and bring the first submenu down however once I move through the submenu the red background goes away from the top link and then goes on whatever link I highlight in the submenu. I also have 2nd level and 3rd level sub menus that I’d like to highlight as I move around but the red hover effect will only stay on one link at a time. Given my css code below what would I need to do to get the hover effect to anchor on each sub menu as I navigate through it. Also a link to the menu in action can be found here: http://www.clubkumite.com/menu.html

Thanks!

Change #nav a:hover to #nav li:hover > a

#nav li:hover > a {
    background-color: #900;
    width: 15em;
}

The > makes sure you’re not selecting all a‘s within the underlying submenu(s) – it selects just the top level a.
