在我的TailwindCSS中，我有這個模板

<script src="https://cdn.tailwindcss.com"></script>

<div class="h-screen min-h-screen ">
    <div class="flex max-h-full">
        <div class="flex">
            <div class="flex flex-col-reverse overflow-auto">
                <div class="flex justify-end h-full max-h-full">
                    <div class="flex items-center group">
                        <div class="bg-gray-500 h-[2000px]">Hover here from a little down</div>
                        <div class="opacity-10 group-hover:opacity-100">Element of Group</div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
