What is tailwind.config.js?

As a web developer, you might have heard about Tailwind CSS – a popular utility-first CSS framework. When you use Tailwind CSS, you can define custom styles for various HTML elements by leveraging a configuration file named tailwind.config.js.

What's inside the tailwind.config.js file?

The Tailwind CSS configuration file is an essential part of any project that uses this CSS framework. It contains various properties that define the style of your application, including:

  • Colors
  • Font sizes
  • Spacing
  • Border radius
  • And much more!

The configuration file exports an object that defines all the custom styles you want to add to your project.

module.exports = {
  theme: {
    extend: {
      colors: {
        'primary': '#E91E63',
        'secondary': '#9C27B0',
  variants: {},
  plugins: []

As you can see from the example above, the configuration file defines a custom color palette with a primary and secondary color. This color palette can then be used throughout your application to maintain consistency.
