CSS Sprites
What is CSS sprite?
CSS sprites can be termed as a method for reducing the number of image requests to a web page by combining multiple images into a single image, and display the desired segment using CSS background-image and background-position properites. Now that almost all major browsers started supporting CSS background-image and background-position properties, CSS sprites are getting more significance.
Here I am presenting a cool overlapped pure CSS menu created using CSS sprites. This is an initial draft version, so far I have checked it only in Firefox 5.0, IE 9, Chrome 5.1 & Opera 11.0 and it looks fine. If anyone of you finds any issues in any other browsers, please let me know. Cool sprites is a pack of four different versions of the same menu.

Code
.navi1 {
display:block;
