CSS Animated Underline Menu
This menu takes the simplicity and elegance of an underline beneath text and animates it for a touch of liveliness. Three effects are presented- drawing the line horizontally, drawing and thickening the line, and finally, drawing and expanding the line to cover the entire menu item.

Mobile full screen expand menu II
An alternate rendition of Mobile full screen menu, this one uses CSS3 scale() to collapse the full screen menu initially, expanding to fill the screen when expanded.

Slide Up Tabs
Slide Up Tabs separates the tab from the menu link and slides up the former whenever the mouse is over an element to add a twist to the regular tabs menu interface.

3D rollover menu
This horizontal menu flips the traditional rollover effect over its head to create a rather unique effect. As the user mouses over a menu item, it rolls up in a 3D fashion like a cube to reveal the bottom side, which is a duplicate of the original menu item's content.

Depressible Circle Buttons
These large, circular buttons employ CSS3 shadows to create a 3D, depressible effect, with hovering over a button causing it to depress. Four different button colors are presented to give you a jump start in inspiration for using these bold menu buttons. Go big -and round- or go home!

3D flip menu
Using CSS3 transform, this menu flips the traditional menu around, or on its y-axis to be exact. When the user clicks on the menu anchor, it flips over to reveal a drop down menu. The menu degrades well in IE9 and IE8, resorting to a drop down menu activated by JavaScript in the later. Flippin' cool!

Responsive Iconic Menu
This sleek horizontal menu bar stays tucked away until the user clicks on an icon, revealing the menu. Using CSS3, various parts of the menu are animated, from the menu unveil to the icon flip when clicked on.
