CSS Spotlight Menu
Spotlight Menu takes advantage of CSS3's border-radius property and transitions to add a circular background to its menu items when the mouse rolls over each one. The result is a Flash-like, sleek spotlight menu!

CSS3 Shadow Block Menu
This CSS Menu harnesses CSS3's ability to define multiple/ inset shadows (so the shadow grows inwards) on an element to create menu items with bevelled edges and a growing inner glow when the mouse rolls over them. CSS3 animation is enabled to gradually transition between various property changes.

Image with sliding description panel using CSS3 transitions
This CSS example shows how to add an animated description panel to images that slides open when the mouse rolls over the image using CSS3 transitions.

Spinning icons using CSS3 transform
An effect that seems to be popping up with increased frequency is the spinning image, or more precisely, icons. Move the mouse over an icon, and it spins (rotates) on its axis to draw attention to itself. This is realized using CSS3's transform: rotate(xdeg) property.

CSS3 animated vertical slanted menu
This is a vertical list menu that uses CSS3 animation to gradually expand the selected menu item horizontally so to highlight it. It also employs the CSS border trick to create a cross browser slanted left edge. The final result is a sleek vertical list menu that uses nothing but pure HTML markup!

Pull out image using CSS3 keyframe animation
CSS3 animation can be fine tuned and broken up into "frames", thanks to the @keyframes rule. Currently supported in FF5+, Safari, Chome, and possibly IE10, the following uses CSS3 keyframes to create a pull out image that is revealed when the mouse rolls over an image. In IE, it degrades well in both IE8 and IE9.

CSS3 Semi Opaque Menu
This menu takes advantage of CSS3 gradient background to produce a menu with a semi opaque rollover effect. Whatever the solid background color of the main UL behind it, the menu item's background peeks through. Peek-a-boo!
