Different types of navigation --
Navbars -- This is just a navbar with simple styling in CSS (Cascading Style Sheet).
Tabs -- This is a navbar that has tabs instead of buttons or just plain links.
Crumbs -- Just like Hansel and Grettel, this navbar leaves a trail so that you can go back to pages that you've already gone to.
Fireworks -- This is a button made and styled in Adobe Fireworks CS3.
Flash -- As above, except in Adobe Flash CS3.
Enjoy!
