问题陈述：
我有一个使用nextjs和tailwindcss的项目。在登录页面上，UI在第一次加载时有必要的类，但如果我刷新页面，则这些类会从DOM中消失，导致UI出现问题。
如何重现？
- 打开上面给定的链接，您将观察到登录表单UI看起来还好。
- Ctrl+R（刷新页面），您将观察到登录界面现在已经损坏。

main标签消失了，还将w-full md:min-w-full bg-CD-black-dark-accent rounded px-8 mx-4 sm:px-16 py-10类更改为h-screen w-full flex justify-center items-center mx-auto max-w-2xl text-white。请检查一下您的 React 应用程序中是否有任何函数更改了这些类。如果没有，请在 codesandbox 上共享以进行进一步调试。 - Surjith S M
