Put an id in the body of each page identifying what page it is. e.g. id="about"
Give each menu item a style you can identify as that page. e.g. class="menuabout"
Then in the CSS create a style for the combination of the id and style. e.g. #about .menuabout with the styling you want to show that it is active.
