Such a pleasure to see a nice tailwind abstraction, at some point inlining starts looking just a bit too much, luckily there is a solution ;)

  /\* tailwind.css \*/
  .card-container {
    @apply flex flex-col md:flex-row items-center justify-between
      w-full max-w-screen-xl px-6 md:px-12 py-8
      bg-white dark:bg-gray-900 border border-gray-200 dark:border-gray-700
      rounded-lg shadow-md space-y-6 md:space-y-0 md:space-x-8
      text-sm text-gray-700 dark:text-gray-300 font-medium tracking-tight leading-relaxed
      hover:bg-gray-50 dark:hover:bg-gray-800 transition-all duration-300 ease-in-out;
  }
