3D flip menu

Author: Dynamic Drive

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!

Site Menu

Site Navigation

The CSS:

<style>

body {  /* webkit adjacent sibling bug fix */
	-webkit-animation: bugfix infinite 1s; 
}

@-webkit-keyframes bugfix { 
	from {padding:0;} 
	to {padding:0;} 
}
