jQuery Effect fadeOut() Method

Fade out all <p> elements:

$("button").click(function(){
$("p").fadeOut();
});

Definition and Usage

The fadeOut() method gradually changes the opacity, for selected elements, from visible to hidden (fading effect).

Note: Hidden elements will not be displayed at all (no longer affects the layout of the page).

Tip: This method is often used together with the fadeIn() method.

$(selector).fadeOut(speed,easing,callback)
