Understanding the "Gotcha":

In this example:

Crucially, clicking the hamburger icon above will NOT open or close the mobile menu. Tailwind provides the classes to show or hide elements, but the *interactive toggling* (making the click work) requires JavaScript. See the HTML comments above the `#mobile-menu` div for more details.

To make it functional, you'd add a script like:


// <script>
//   document.getElementById('hamburger-button').addEventListener('click', function() {
//     document.getElementById('mobile-menu').classList.toggle('hidden');
//   });
// </script>
// (This JS would typically be at the end of the <body> or in a separate .js file)
        

Try resizing your browser window. The visibility of the hamburger icon and desktop links will change correctly due to Tailwind's responsive classes. The interactivity is the part that needs custom JavaScript.
