By default, the menu is presented in black with current page and hovered anchor highlighted in grey. This can easily be changed by applying a few modifications into the stylesheet of the menu.
Menu stylesheet is located inside plugin folder inside folder css and is called cfm_menu.css.
Complete path would be: WP_INSTALLATION/plugins/codeflavors-floating-menu/css/cfm_menu.css

Menu placed into menu location provided by the plugin is the default menu output WordPress provides and is structured as an unsorted list. When applying modifications to CSS, look for the comment MENU DESIGN – do all design changes below.

Menu is wrapped inside a div container having id #cfn_floating_menu. All styling should descend from this container; in some cases styling might not apply due to different styling from theme or other plugins. In this case, a more in depth analysis should be performed and menu styling changed accordingly.

CSS responsible for colors, fonts and general aspect or the menu is presented below:

/**
 * MENU DESIGN - do all design changes below
 */	

/**
 * Menu container
 */		
#cfn_floating_menu ul{
	-moz-box-shadow:2px 2px 2px #CCC;
	-webkit-box-shadow:2px 2px 2px #CCC;
	 box-shadow:2px -1px 4px #CCC;
}
	/**
	 * Menu anchor container
	 */
	#cfn_floating_menu ul li{
		font-size:12px;
		border-bottom:1px #2B2B2B solid;
	}
		/**
		 * Menu anchor
		 */
		#cfn_floating_menu ul li a{
			background:#000;
			color:#FFF;
			text-decoration:none;
		}
		/**
		 * Hovered and active anchor design
		 */
		#cfn_floating_menu ul li a:HOVER,
		#cfn_floating_menu ul li a.currentItem{
			color:#FFF;
			background:#999;					
		}
