Slanted Divider Menu is a Scripts software developed by Dynamic Drive. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Slanted Divider Menu:

BSEditor: We got our Inspiration for this menu from Simplebit's bulletproof slants. It's an elegant CSS menu bar that uses a transparent "slanted" image to act as a divider and separate each menu item. Change the background color of the menu as desired. It differs from the Simplebits code in that no floating is used, enabling you to easily align the menu items either to the left, center, or right, just by changing the "text-align" property within the CSS code.
