Dark Mode and TailwindCSS Integration in Modern Web

In UX-focused websites, a dark theme is no longer a luxury but a necessity. How do we build the most stable dark theme with Tailwind?

Managing the HTML Class

The safest way to manage dark theme is to dynamically add the dark class to the <html> or <body> tag.

// A simple theme toggler in React
const toggleTheme = () => {
  document.documentElement.classList.toggle('dark');
};

Make sure you have darkMode: 'class' in your Tailwind settings. This way, your CSS system is managed under your site's control instead of blindly following the user's OS theme.
