How To Toggle Class Using Pure Javascript In Html

Toggling class using pure JavaScript in HTML is a great way to dynamically change the styling or behavior of an element on your web page without the need to reload the entire page. This can come in handy when you want to add or remove specific styles or functionality based on user interactions, such as clicking a button or hovering over an element. In this article, we will walk you through a simple guide on how to toggle a class using pure JavaScript in your HTML code.

To get started, let's first understand what toggling a class means. When we toggle a class, we are essentially adding the class if it is not already present, and removing it if it is. This allows us to switch between two different states easily. This can be achieved using JavaScript by manipulating the class attribute of an HTML element.

Here is a step-by-step guide on how to toggle a class using pure JavaScript:

1. Select the element you want to target: You can do this by using document.getElementById, document.querySelector, or any other DOM selection method to select the element on which you want to toggle the class.

2. Create a function to toggle the class: Next, you need to write a JavaScript function that will be triggered when an event occurs (e.g., a click event). Inside this function, you will toggle the class of the selected element.

3. Implement the toggle functionality: Within your JavaScript function, you can use the classList.toggle method to toggle a class on or off. This method checks if the class is present and adds it if it's not, or removes it if it is.

Here is a simple example to demonstrate how you can toggle a class using pure JavaScript in your HTML code:

<title>Toggle Class Example</title>



<button id="toggleButton">Click me to toggle class</button>

<div id="targetElement">This is the element to toggle class on</div>


function toggleClass() {
  var element = document.getElementById('targetElement');
  element.classList.toggle('highlight');
}



.highlight {
  background-color: yellow;
}

In this example, whenever the button is clicked, the `highlight` class will be toggled on and off on the `targetElement`.

By following these simple steps, you can easily implement class toggling using pure JavaScript in your HTML code. This technique can add interactivity and enhance the user experience of your website or web application.
