Creating Beautiful Dark Mode for Your Website

Why Dark Mode?

Dark mode isn't just a trend – it reduces eye strain, saves battery on OLED screens, and many users simply prefer it.

Implementation with Tailwind CSS

Configure Tailwind for class-based dark mode:

// tailwind.config.js
module.exports = {
    darkMode: "class",
    // ...
}

The Toggle Logic

// Check system preference
if (window.matchMedia("(prefers-color-scheme: dark)").matches) {
    document.documentElement.classList.add("dark");
}

// Toggle function
function toggleDarkMode() {
    document.documentElement.classList.toggle("dark");
    localStorage.setItem("darkMode", 
        document.documentElement.classList.contains("dark"));
}

Using Dark Mode Classes

<div class="bg-white dark:bg-gray-900 text-gray-900 dark:text-white">
    This adapts to dark mode!
</div>

Best Practices

• Use subtle background differences, not pure black
• Reduce brightness of colors, don't just invert
• Test contrast ratios for accessibility
• Remember user preference across sessions

A great dark mode implementation shows attention to detail. Your users will appreciate it!
