Introduction to Animate in jQuery

Animate() in jQuery is a pre-defined function that uses the CSS properties for performing sequential or non-sequential animation customization with the help of the queue & toggle functionality. The syntax for this function is ‘$(selector).animate(properties, options)’, which contains many CSS properties and parameters. The commonly used parameters are duration, easing and function similar to other jQuery functions, and also other parameters like queue, complete, start, done, fail and step.

Syntax:

 $(selector).animate(properties, options);

Properties:

It specifies the CSS properties to animate.
It contains many parameters.

Parameters:

Below are the details of the Parameters:

Duration: The duration can be a string or a number. It can be either a time in milliseconds or it can be preset. The default value of the duration is 400 milliseconds. It can take slow, fast or normal as a string parameter. This helps us to control the slide animation based on our requirements.
Easing: The easing should be of string type. It is used for transition. The default value is swing.
Function: An optional callback function will be executed when the animation is completed.
Queue: The queue takes the Boolean value. If the Boolean value is true it indicates whether to place or not to place the animation. If the Boolean value is false the animation will take place immediately.
Complete: This function is called once the animation is completed on an element.
Start: This function is called when the animation on an element begins.
Done: This function is called when the animation on an element is complete.
Fail: This function specifies when the animation fails to complete.
Step: For each step in the animation it specifies the function to be executed.

$("#box2").animate({top: '150px'});
$("#box3").animate({right: '150px'});
$("#box4").animate({left: '150px'});
});
});
</script>
</head>
<body>
<button id="btn">Animate top, bottom, right and left</button>
<div id="box1" style="background:blue;height:100px;width:100px;margin:6px;position:relative;"></div>
<div id="box2" style="background:blue;height:100px;width:100px;margin:6px;position:relative;"></div>
<div id="box3" style="background:blue;height:100px;width:100px;margin:6px;position:relative;"></div>
<div id="box4" style="background:blue;height:100px;width:100px;margin:6px;position:relative;"></div>
</body>
</html>

<script>
$(document).ready(function(){
$("#btn").click(function(){
$("#square").animate({width: 'toggle'});
});
});
</script>
</head>
<body>
<button id="btn">Animate width</button>
<div id="square" style="background:blue;height:100px;width:100px;margin:6px;"></div>
</body>
</html>
