Certain parts of tailwind CSS not working in production

I've built a static website for my next JS app that uses tailwind CSS for styling. I'm using statically as a CDN. The website in the development server(local host) works perfectly alright. However, in production, certain parts of styling seem to be broken (Header, Footer, and toggling between dark/light mode to be precise).

Local server:

Production:

When I inspect the corresponding elements in local and production env, there seems to be no difference in the HTML structure and class names, but when I hover over the broken elements (nav items in this case) in production, the corresponding elements are not being highlighted. So far this is what I was able to find. Below are few config files:
next.config.js:

const isProd = process.env.NODE_ENV === 'production'
module.exports = {
  reactStrictMode: true,
  
  images: {
    // domains: ['raw.githubusercontent.com','ibb.co'],
    domains: ['raw.githubusercontent.com'],
    loader:'imgix',
    path:''
  },
  assetPrefix: isProd ? 'CDN_LINK_HERE' : '',
}

tailwind.config.css :

module.exports = {
  purge: ['./pages/**/*.{js,ts,jsx,tsx}', './components/**/*.{js,ts,jsx,tsx}'],
  darkMode: 'class', // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [],
}

How do I go about fixing this?

Ensure to add a complete list of paths you need your CSS applied to in the purge array of tailwind.config.css.

module.exports = {
// ▼ here you need to add all paths according to your needs
  purge: ['./pages/**/*.{js,ts,jsx,tsx}', './components/**/*.{js,ts,jsx,tsx}', './your-other-component-folder/**/*.{js,ts,jsx,tsx}'], 
  darkMode: 'class', // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [],
}
