Answer
To implement a dark mode toggle in a Tailwind CSS project, you can use the "dark mode" feature that Tailwind provides. This involves setting up your Tailwind configuration to support dark mode and using the appropriate utility classes to style elements conditionally based on the mode.
<!-- BEGIN COPY / PASTE -->
<!-- Tailwind configuration (tailwind.config.js) -->
module.exports = {
darkMode: 'class', // or 'media' for automatic based on user preference
theme: {
extend: {},
},
plugins: [],
};
<!-- HTML Example -->
<div class="bg-white dark:bg-gray-800 text-black dark:text-white p-4">
<button onclick="document.documentElement.classList.toggle('dark')">
Toggle Dark Mode
</button>
<p>This text changes color based on the mode.</p>
</div>
<!-- END COPY / PASTE -->Additional Comment:
- Set "darkMode" to "class" in your Tailwind configuration to manually toggle dark mode using a class.
- Use "dark:" prefix in your utility classes to apply styles in dark mode.
- Toggle the "dark" class on the root element (e.g.,
document.documentElement) to switch modes. - Consider storing the mode preference in local storage for persistence across sessions.
