Below is a minimal working Hugo app using Tailwind CSS.

        <title>My Hugo App</title>
        <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/tailwindcss/1.7.2/tailwind.min.css" integrity="sha512-jC/Z9GKvNv+yyW8/NugwKbE/NUgx6Gm+uxUZJHXpzsUyT6T+TmUY2FdKm6Jx1xhG8Ao7DfXA2OvAgPhJLF8hg==" crossorigin="anonymous" />
    </head>
    <body class="bg-gray-800 text-white">
        <div class="container mx-auto">
            <h1 class="text-2xl font-semibold mb-4">My Hugo App</h1>
            <p class="mb-4">Welcome to my Hugo app!</p>
