By default, Tailwind does not provide transition-property utilities for the height property. You'll need to add it to your tailwind.config.js file for the transition to work.

module.exports = {
    theme: {
        extend: {
            transitionProperty: {
                height: 'height'
            }
        }
    }
}

From Tailwind v3, you can now use an arbitrary value to generate a one-off transition-property on the fly, without changing your tailwind.config.js file.

<div class="transition-[height]">
    <!-- ... -->
</div>
