)。 Tailwind CSS 类在这里广泛用于样式设计，包括悬停效果和深色模式兼容性。
添加注册按钮
菜单项之后，我们将添加一个注册按钮：
<button
className="mt-4 md:mt-0 rounded-full bg-slate-800 py-2 px-4 border border-transparent text-center text-sm text-white transition-all shadow-md hover:shadow-lg focus:bg-slate-700 focus:shadow-none active:bg-slate-700 hover:bg-slate-700 active:shadow-none disabled:pointer-events-none disabled:opacity-50 disabled:shadow-none"
type="button"
>

</button>

此按钮的设计风格引人注目，并为用户提供了明确的号召性用语。我们添加了悬停和焦点状态以获得更好的用户体验。
为移动设备添加汉堡图标
为了使标题具有响应能力，我们将为移动用户添加一个汉堡菜单图标：
<div className="md:hidden flex items-center lg:order-1">
<button
type="button"
className="inline-flex items-center p-2 ml-1 text-sm text-gray-500 rounded-lg hover:bg-gray-100 focus:outline-none focus:ring-2 focus:ring-gray-200 dark:text-gray-400 dark:hover:bg-gray-700 dark:focus:ring-gray-600"
aria-controls="mobile-menu"
aria-expanded={nav}
onClick={() => setNav(!nav)}
>
<span className="sr-only">Open main menu</span>
</button>
</div>
登录后复制
此代码创建一个按钮，单击该按钮会切换导航菜单的可见性。 aria-controls 和 aria-expanded 属性增强了可访问性。
处理图标更改
根据导航菜单是打开还是关闭，我们可以显示不同的图标：
{nav ? (
<svg /* close icon */></svg>
) : (
<svg /* open icon */></svg>
)}
登录后复制
这种条件渲染使我们能够向用户提供有关菜单状态的视觉提示。
