Based on email from Anne of Murach books h3
uses menu-vert-anim_AdamB6_Flex.css which has all cNav CSS in this file.
Has the nav.vertical class-selector. Formatting cmds unresponsive and can't even set no-underline for menu boxes. Need to really understand what's setting the styles for the AB NavBar.
list-style-type: none; /* i.e. no underline */
