jQuery Fading Methods
jQuery has the following fade methods:
- fadeIn()
- fadeOut()
- fadeToggle()
- fadeTo()
The optional speed parameter specifies the duration of the effect. It can take the following values: "slow", "fast", or milliseconds.
The optional callback parameter is a function to be executed after the fading completes.
jQuery fadeIn() Method
The jQuery fadeIn() method is used to fade in a hidden element.
Syntax:
$(selector).fadeIn(speed,callback);
Example:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("#div1").fadeIn();
$("#div2").fadeIn("slow");
$("#div3").fadeIn(3000);
});
});
</script>
</head>
<body>
<p>Demonstrate fadeIn() with different parameters.</p>
<button>Click to fade in boxes</button>

<div id="div1" style="width:80px;height:80px;display:none;background-color:red;"></div><br>
<div id="div2" style="width:80px;height:80px;display:none;background-color:green;"></div><br>
<div id="div3" style="width:80px;height:80px;display:none;background-color:blue;"></div>

jQuery fadeOut() Method
The jQuery fadeOut() method is used to fade out a visible element.

jQuery fadeToggle() Method
The jQuery fadeToggle() method toggles between the fadeIn() and fadeOut() methods.
If the elements are faded out, fadeToggle() will fade them in.
If the elements are faded in, fadeToggle() will fade them out.

$(document).ready(function(){
$("button").click(function(){
$("#div1").fadeToggle();
$("#div2").fadeToggle("slow");
$("#div3").fadeToggle(3000);
});
});
</script>
</head>
<body>
