Dark mode gives your website a sleek aesthetic while reducing strain on users’ eyes during nighttime usage. With Tailwind CSS natively supporting dark mode as of version 2.0, integrating it into your project is seamless. Let’s unravel the steps to successfully set up dark mode in your Tailwind CSS project!

Step 1: Installation

First things first, you need to install the Tailwind CSS dark mode plugin. This is a one-time setup that will enhance your UI experience.

npm install tailwindcss-dark-mode --save-dev

Step 2: Adding the Plugin

Now that you have the plugin, it’s time to enable it in your Tailwind configuration file.

plugins: [
  require('tailwindcss-dark-mode')()
]

Step 3: Using the Dark Mode Styles

Styles generated by this plugin only activate when a specific selector is applied to the HTML element. You can utilize the provided prefers-dark.js script, which dynamically adjusts the theme according to the user’s system preferences.

Here’s a quick analogy: Think of your dark mode as a light switch in your room. When you flip the switch (apply the selector), the lights (styles) either glow brightly or dim down to a softer hue based on your choice.

Available Variants

In Tailwind CSS, you can leverage the following dark mode variants:

• dark-
• dark-hover
• dark-focus
• dark-active
• dark-disabled
• dark-group-hover
• dark-focus-within
• dark-even
• dark-odd
• dark-placeholder

Here is an example of how you can structure your HTML with dark mode in mind:

<div class="bg-white dark:bg-black p-4">
  <p class="text-black dark:text-white">My eyes are grateful.</p>
  <a class="text-blue-300 hover:text-blue-400 dark:text-blue-700 dark-hover:text-blue-600">Learn more</a>
</div>

Step 4: Enabling Variants

Similar to hover and focus variants, you must enable dark mode variants in the Tailwind configuration.

variants: {
  backgroundColor: ['dark', 'dark-hover', 'dark-group-hover', 'dark-even', 'dark-odd'],
  borderColor: ['dark', 'dark-disabled', 'dark-focus', 'dark-focus-within'],
  textColor: ['dark', 'dark-hover', 'dark-active', 'dark-placeholder'],
}

Remember, dark mode variants complement existing Tailwind variants. For instance, if you utilize dark-hover, ensure you also enable hover.

Step 5: Changing the Selector

By default, Tailwind uses .mode-dark as the selector for dark mode. Feel free to change this by adding the darkSelector key to the theme section of your configuration.

theme: {
  darkSelector: '.custom-dark-mode' // example of custom selector
}

Make sure to modify the selector in prefers-dark.js if you’re using that as well!

Step 6: Handling PurgeCSS

If you’re employing PurgeCSS, it is essential to whitelist the dark mode selector to prevent it from being stripped away during the build process.

whitelist: ['mode-dark']

Alternatively, include prefers-dark.js in the content array to ensure that the necessary classes remain intact.

content: [
  './**/*.js',
  './node_modules/tailwindcss-dark-mode/prefers-dark.js',
  './your-own-prefers-dark.js',
]

Troubleshooting

If you encounter any issues while implementing dark mode, consider the following tips:

• Ensure that your prefers-dark.js file is linked correctly.
• Double-check your Tailwind configuration to confirm the plugin is included in the plugins array.
• Visit the relevant links in the Tailwind documentation to ensure your setup matches their guidelines.
• For persistent issues, clear your build cache and recompile your assets.
