How To Toggle Css In Jquery

jQuery is a powerful and easy-to-use JavaScript library that simplifies the process of working with HTML documents. One of the most common tasks web developers face is the need to toggle CSS styles on various elements. In this blog post, we’ll explore how to use jQuery to toggle CSS on elements in your web application.


Before we begin, you’ll need to have the following:

  • Basic knowledge of HTML, CSS, and JavaScript
  • jQuery library added to your project

If you haven’t already added jQuery to your project, you can include it by adding the following script tag to the head of your HTML file:<script src=””></script>

Toggle CSS using the toggleClass method

jQuery provides a handy method called toggleClass that allows you to toggle a CSS class on an element. The basic syntax for the toggleClass method is as follows:


The selector is a string that represents the element(s) you want to target, and className is the CSS class you want to toggle on the targeted element(s).

Let’s look at an example. Assume we have the following HTML structure:

<button id=”toggleButton”>Toggle CSS</button>
<div id=”box”></div>

And, we have the following CSS class:

.red-background {
background-color: red;

We want to toggle the .red-background class on the #box element when the button with the ID toggleButton is clicked. Here’s the jQuery code to achieve this:

$(document).ready(function() {
$(“#toggleButton”).on(“click”, function() {

With this code, every time the button is clicked, the #box element will either gain or lose the .red-background class, causing the background color to toggle between red and its default color.


In this blog post, we’ve learned how to use the jQuery toggleClass method to easily toggle CSS classes on elements in your web application. This method is a simple and effective way to add interactivity to your website, allowing you to create dynamic interfaces that respond to user input.
