How to useTailwind CSS Utility Classes in Javascript
In this approach, the Tailwind CSS framework and JavaScript dynamically display the active breakpoint and screen size by listening to window resize events and applying specific styles based on the viewport width.
Syntax:
<div id="app" class="bg-red-200
sm:bg-blue-200
md:bg-green-200
lg:bg-yellow-200
xl:bg-pink-200
p-4">
</div>
Example: In this example, we are using the Tailwind CSS utility classes for screen sizes or breakpoints. Using the JavaScript, we are dynamically updating and displaying the active breakpoint and screen size. JavaScript listens for window resize events and also updates the displayed breakpoint and screen which is based on media query breakpoints.
