Fading elements in and out example

For fading effect jQuery has following three methods :

.fadeIn( )

This method fade the matched elements to opaque.

Example :

Following code animates hidden divs to fade in :

$("div:hidden:first").fadeIn("slow");

.fadeTo( )

This method can be used for adjusting the opacity of the matched elements.

Example :

Following code change the opacity of the image :

$('#clickmeDiv').click(function() {
$('#image').fadeTo('slow', 0.5, function() {
// Animation complete.
});
});

.fadeOut( )

This method hide the marched element and set their visibility to transparent.

Example :

In this Example, a list is given , if we hover on first two element, "<<<" is appended on it, to show mouse pointing. If we hover on last two elements ,"<<<" is appended on it & it will fade out/in to show mouse pointing.
