How to add a div class to menu link?
Menu CSS Names


  This is a very simple module that takes the link text of each drupal
  menu item and adds it as a css class name to the menu's element.
  Using these class names, each menu item can be styled separately with
  css. This is also very useful for css sprite techniques.
  
  There are no admin settings for this module, it starts doing its work
  once the module is enabled. All caches are automatically cleared at
  this time also. This module works with menus in blocks (including
  Primary Links) and menus in themes (menus that are enabled from the
  theme's configuration page).
