πŸŒ™ Introduction

While I was leisurely scrolling through my Discord server, my eyes snagged on an intriguing discussion about darkmode vs. non-darkmode (light mode): So I decided to write about how I implemented Darkmode 🌝

If you’re new to Astro, it’s a static site generator that has quickly risen to fame for its performance and flexibility. With Astro, you can seamlessly integrate multiple frameworks like Vue, React, and yes, Tailwind CSS, making it an ideal choice for web development. Dark mode is not just a trendy feature; it improves readability and reduces eye strain, crucial attributes for any content-based website.

🌚 Why Dark Mode?

The adaptability of dark mode is especially crucial for content-heavy platforms. It not only provides a visually appealing contrast but also has functional merits like reduced eye strain and battery conservation on OLED screens.

πŸ§‘πŸ»β€πŸš€ Setting Up Dark Mode in Tailwind with Astro

To enable dark mode, add the following configuration to your tailwind.config.js:

module.exports = {
  darkMode: 'class', // or 'media' based on preference
  // of the config

This 'class' option toggles dark mode based on a class. You can also use 'media' to toggle based on the prefers-color-scheme media query.

πŸŒ— Defining Custom Colors

Tailwind enables fine-grained control over your color scheme. You can define dark mode-specific colors using the dark: prefix:

<div class="bg-orange-50 dark:bg-sky-950">
  <!-- Content -->

Here, bg-orange-50 is the default background, while dark:bg-sky-950 kicks in when dark mode is activated.

🌜 Toggling Dark Mode

A simple way to toggle dark mode is by adding or removing a .dark class to the <html> or <body> tag:
