When Click On Radio Button Change Css Js

Web Development Software

When it comes to web development, I am always eager to explore new ways to enhance user experience. One interesting aspect that I recently delved into is the ability to change CSS styles using JavaScript when a radio button is clicked. This functionality can greatly enhance the interactivity of a web page, and I’m excited to share what I’ve discovered.

Understanding the Basics

First, let’s understand the basic structure of a radio button. A radio button is an input control that allows the user to select only one option from a set. When a radio button is selected, it triggers a change event, which we can utilize to dynamically modify the CSS styles of other elements on the page.

Implementing the Solution

To implement the functionality of changing CSS styles when a radio button is clicked, we can use JavaScript to listen for the change event on the radio button. Once the change event is detected, we can then use JavaScript to access the desired elements on the page and modify their CSS properties accordingly.

For example, let’s say we have a radio button with the id “lightTheme” and we want to change the background color of the entire page to white when this radio button is selected. We can achieve this by using JavaScript to listen for the change event on the “lightTheme” radio button, and then accessing the document.body element to modify its backgroundColor CSS property.

Code Implementation

document.getElementById(‘lightTheme’).addEventListener(‘change’, function() {
document.body.style.backgroundColor = ‘white’;

Similarly, we can apply different styles based on the selection of different radio buttons. This could include changing font styles, adjusting element positioning, or even applying animations to elements based on the radio button selection.

Putting It into Practice

Now that we understand the concept and implementation, it’s time to put it into practice. By incorporating this functionality, we can provide users with the ability to personalize their experience on our web page. Whether it’s choosing a preferred color scheme, layout, or any other stylistic preference, the ability to dynamically change CSS styles based on radio button selection can significantly enhance user engagement.


Exploring the intersection of JavaScript and CSS opens up a world of possibilities for creating dynamic and interactive web experiences. By leveraging the change event of radio buttons, we can seamlessly enhance the user interface and provide a more personalized browsing experience. So, the next time you’re looking to add an extra layer of interactivity to your web projects, consider the impact of changing CSS styles when radio buttons are clicked!
