How to add a style on a condition in Tailwind CSS ?
In this article, we will see how to integrate conditional styling into our web projects using Tailwind CSS. There are various Tailwind CSS classes are available, although, it usually involves dynamically adding or removing classes using JavaScript. There are different approaches to implementing the styling properties conditionally:
- By Implementing the Dynamic Class Binding
- By using the dynamic based on the different button clicks
We will explore both approaches to include the styling properties conditionally, along with understanding them through the illustrations.
The following Tailwind CSS classes will be used:
- bg-gray-100
- flex
- items-center
- justify-center
- rounded-lg
- text-lg
- mt-6
Adding Conditional Styling using the Dynamic Class Binding
In this approach, we are performing conditional Styling using Dynamic Class Binding in Tailwind CSS. Here, we are toggling the styles and different animations on the button click where the changes in the colors and text appearance are been done.
Example: This example illustrates the Adding Conditional Styling in Tailwind CSS.

Adding Conditional Styling using dynamic change
In this approach, we will change the background dynamically by toggling the button, i.e., we use conditional styling in Tailwind CSS framework where we can change the background color of the page dynamically based on the different button clicks.
Example: This is another example that illustrates the Conditional Styling of the web page by using the button click.
