This tutorial explais how to design an high impact elastic effect to make original web menu using some lines of Javascript code and MooTools framework. The effect is simple to develope and reuse in your web projects changing only HTML code and CSS. Take a look!
The effect I want to realize is the following. I have a "layer cloud" with some layer overlapped to the others. On "mouse over" the select layer goes down with a nice animation effect and when you release the element this goes up with an elastic effect:

The result is something like this, a "layer cloud" with some layer overlapped to others:
You can add other overlapped layers simply adding new <div> elements in step (1) with the related CSS stlye in step 2. To overlap layer I use CSS properties "position:absolute" and "z-index" for each element.
No fear... it's very simple! In the <head> tag of the page add a link to MooTools:
Now, copy and paste this code below the previous line of code in the <head> tag of the page (if you prefer you can also copy this code in a separated .js file and import it in your page):
In this code I used a MooTools basic knowledge. In the past week I already dedicated several lessons about that. I suggest you to take a look at these post:

Live Preview1. HTML code
Create a layer which contains all elements in the "cloud" (in this case I used DIV elements):<div id="container">
<div id="contact">This is the layer about me.</div>
<div id="about">Contact me? <a href="mailto:myemail@email.com">My Email</a></div>
<div id="profile">This is my <a href="http://woork.blogspot.com">website</a></div>
</div><div id="about">Contact me? <a href="mailto:myemail@email.com">My Email</a></div>
<div id="profile">This is my <a href="http://woork.blogspot.com">website</a></div>
2. CSS Code
Use CSS to stylize previous elements how you prefer. In this tutorial I used this CSS code:#about {
width: 200px;
padding: 8px;
background: #DEDEDE;
color: #333;
position: absolute;
z-index: 1;
left: 31px;
top: 66px;
border:solid 4px #CCC;
}
#about {
width: 200px;
padding: 8px;
background: #DEDEDE;
color: #333;
position: absolute;
z-index: 1;
left: 80px;
top: 37px;
border:solid 4px #CCC;
}
...
width: 200px;
padding: 8px;
background: #DEDEDE;
color: #333;
position: absolute;
z-index: 1;
left: 31px;
top: 66px;
border:solid 4px #CCC;
}
#about {
width: 200px;
padding: 8px;
background: #DEDEDE;
color: #333;
position: absolute;
z-index: 1;
left: 80px;
top: 37px;
border:solid 4px #CCC;
}
...

3. JavaScript code
In order to obtain our elastic effect I used MooTools framework and some lines of Js code.No fear... it's very simple! In the <head> tag of the page add a link to MooTools:
<script type="text/javascript" src="mootools.svn.js"> </script>
Now, copy and paste this code below the previous line of code in the <head> tag of the page (if you prefer you can also copy this code in a separated .js file and import it in your page):
<script type="text/javascript">
window.addEvent('domready', function(){
var zindex = 2;
$('#container div').each(function(item){
var o = item.id
var fx = new Fx.Style(o, 'margin-top', {
duration: 1000,
transition: Fx.Transitions.Back.easeInOut,
wait: true
});
})
});
</script>var zindex = 2;
$('#container div').each(function(item){
var o = item.id
var fx = new Fx.Style(o, 'margin-top', {
duration: 1000,
transition: Fx.Transitions.Back.easeInOut,
wait: true
});
item.addEvents({
'mouseenter' : function(e){
fx.stop()
fx.start(0,100);
zindex = zindex + 1;
$(o).setStyle('z-index', zindex)
},
'mouseleave' : function(e){
fx.stop()
fx.start(0);
zindex = zindex - 1;
$(o).setStyle('z-index', zindex)
}
}); 'mouseenter' : function(e){
fx.stop()
fx.start(0,100);
zindex = zindex + 1;
$(o).setStyle('z-index', zindex)
},
'mouseleave' : function(e){
fx.stop()
fx.start(0);
zindex = zindex - 1;
$(o).setStyle('z-index', zindex)
}
})
});
In this code I used a MooTools basic knowledge. In the past week I already dedicated several lessons about that. I suggest you to take a look at these post:

- Lesson 2 - Get elements ID using unobtrusive code
- Lesson 3 - Interaction with Forms
