Javascript – Animate accordion panel using tailwind classes

I want to add Tailwind classes to animate the opening and closing of the accordion in the code below. I’ve added all the classes, but it doesn’t have any animation. How can I achieve what I want?

    <script>
      function toggleAccordionContent(element) {
        const content = element.nextElementSibling;

        if (content.classList.contains('hidden')) {
          content.classList.remove('hidden');
          content.classList.remove('max-h-0', 'opacity-0');
          content.classList.add('max-h-screen', 'opacity-100');
        } else {
          content.classList.add('hidden');
          content.classList.add('max-h-0', 'opacity-0');
          content.classList.remove('max-h-screen', 'opacity-100');
        }
      }
    </script>

          onclick="toggleAccordionContent(this)"
        >
          <!-- Chevron or other content goes here -->
          <span class="font-semibold">Accordion Title</span>
        </div>
        <div

          <div class="p-4 bg-white">
            <!-- Content goes here -->
            <p>
              This is the content inside the accordion. You can place any HTML
              content here.
            </p>
          </div>
        </div>
      </div>
      <!-- Repeat above block for additional accordion items -->
    </div>
  </body>
</html>

    You can create custom animations in tailwindcss inside your tailwind.config.js configuration file. To do this, follow the instructions in the documentation.

    Example for a wiggle animation :

    // tailwind.config.js
module.exports = {
  theme: {
    extend: {
      // your custom keyframes animations
      keyframes: {
        wiggle: {
          '0%, 100%': { transform: 'rotate(-3deg)' },
          '50%': { transform: 'rotate(3deg)' },
        }
      }
      // your custom animation property
      animation: {
        wiggle: 'wiggle 1s ease-in-out infinite',
      }
    }
  }
}

    <div class="animate-wiggle">My Animated Element</div>

    Transitions do not play on the same frame that an element’s display gets changed from/to none.

    Instead, you could consider applying visibility: hidden. This still hides the element’s descendents from the element tree (i.e. accessibility tree, focus order, interactivity, etc.) but allows transitions to play.

        if (content.classList.contains('invisible')) {
          content.classList.remove('invisible', 'max-h-0', 'opacity-0');
          content.classList.add('max-h-screen', 'opacity-100');
        } else {
          content.classList.add('invisible', 'max-h-0', 'opacity-0');
          content.classList.remove('max-h-screen', 'opacity-100');
        }
      }
