In this tutorial, we will introduce you to the basics of creating animations with jQuery. jQuery is a popular JavaScript library that simplifies HTML document manipulation, event handling, and animation.
You will learn how to use jQuery's built-in animation methods to create smooth, visually appealing animations on your websites. By the end of this tutorial, you'll be able to create animations such as smooth scrolling, fading, sliding, and more.
Prerequisites:
- Basic understanding of HTML and CSS
- Basic understanding of JavaScript
jQuery provides several built-in animation methods, such as .hide()
, .show()
, .toggle()
, .slideUp()
, .slideDown()
, .slideToggle()
, .fadeIn()
, .fadeOut()
, and .animate()
. These methods change the CSS properties of HTML elements over a period of time, giving the illusion of animation.
Here are tips and best practices when working with jQuery animations:
$(document).ready()
function to ensure that your jQuery methods won't run until the document is fully loaded.speed
parameter to specify the duration of the animation. callback
parameter to execute a function after the animation completes.Below are examples of jQuery animation methods:
Example 1: .hide()
and .show()
$(document).ready(function(){
$("button").click(function(){
$("#div1").hide(1000); // Hide the element over 1000 milliseconds (1 second)
$("#div2").show(800); // Show the element over 800 milliseconds (0.8 seconds)
});
});
In this example, clicking the button will hide div1
and show div2
.
Example 2: .slideUp()
, .slideDown()
, and .slideToggle()
$(document).ready(function(){
$("#hide").click(function(){
$("p").slideUp(); // Hide the paragraphs with a slide up effect
});
$("#show").click(function(){
$("p").slideDown(); // Show the paragraphs with a slide down effect
});
$("#toggle").click(function(){
$("p").slideToggle(); // Toggle the visibility of the paragraphs with a slide effect
});
});
In this example, the paragraphs will slide up when the "hide" button is clicked, slide down when the "show" button is clicked, and toggle visibility when the "toggle" button is clicked.
Example 3: .fadeIn()
, .fadeOut()
, and .animate()
$(document).ready(function(){
$("#fadeout").click(function(){
$("#div").fadeOut(); // Fade out the div element
});
$("#fadein").click(function(){
$("#div").fadeIn(); // Fade in the div element
});
$("#animate").click(function(){
$("#div").animate({left: '250px'}); // Move the div element 250px to the right
});
});
In this example, the div element will fade out when the "fadeout" button is clicked, fade in when the "fadein" button is clicked, and move to the right when the "animate" button is clicked.
In this tutorial, we covered the basics of jQuery animations. We learned how to use jQuery's built-in animation methods to create smooth animations on our websites. For further learning, explore more complex animations using the .animate()
method, or try combining multiple animation methods for more interesting effects.

Exercise 1: Create a button that, when clicked, hides a div element with a slide up effect and shows another div element with a fade in effect.
Exercise 2: Create a button that, when clicked, toggles the visibility of a paragraph with a slide effect and moves a div element 200px to the right.
Exercise 3: Create a button that, when clicked, hides all images on the page with a fade out effect and shows a hidden message with a slide down effect.
