Creating Custom Utilities in Tailwind

Introduction

Tailwind CSS is a utility-first CSS framework that allows developers to build custom designs without leaving their HTML. While it comes with a comprehensive set of predefined utility classes, sometimes you might need to create custom utilities to meet specific design requirements.

Why Create Custom Utilities?

Step-by-Step Guide

Follow these steps to create custom utilities in Tailwind CSS:

1. Set up your Tailwind CSS configuration file if you haven't already.
2. Open the tailwind.config.js file.
3. Add custom utilities under the extend section of theme:

module.exports = {
  theme: {
    extend: {
      spacing: {
        '128': '32rem',
        '144': '36rem',
      },
      colors: {
        'custom-blue': '#1e40af',
      }
    },
  },
  variants: {},
  plugins: [],
}

1. Utilize the custom utilities in your HTML files:

<div class="w-128 h-128 bg-custom-blue">
