How to highlight current location in WordPress main navigation bar

In the css, if you add the following code:


li.current_page_item{
/* Change the background color below to control how the navigation/menu section you're in changes color. */
background:#3c78a7;
color:#777;
}


the background will change colors. :-D

Correction:

That hack only works if you’re in the TOP LEVEL menu pages. As soon as you go one level deep, it quits working. Argh.
