About a month before I have provided my first mootools slider. Which is so much popular thanks for your response.

So I have created a new slider using mootools. I have named it Z Slider.

What is Z Slider?

I have used the z-index css property to make this slider work. so I have named it Z Slider.

What is z-index?

If you are new to css or js then just check what is z-index from w3schools.

You can find the demo for the Z Slider at Here.
You can also download the Z Slider from here.

Hope you find this plugin useful for you.

Let us know by your expression. :)
