Jquery implements the general version of the mouse through the fade in effect

 
<a class="jq_btn" href="#"><div></div></a> 
//Mouse over effect
$(".jq_btn").hover(function(){ 
$(this).find("div").stop().fadeIn(); 
},function(){ 
$(this).find("div").stop().fadeOut(); 
}); 

The principle is simple

A label background is set to normal state

Div background sets the hover background for the mouse

You just add to the elements

 
class="jq_btn" 

It all works automatically
