Headless UI + Tailwind CSS Resource | Published on : 7th June, 2023


Building scalable, and adaptable apps is a key goal in the field of web development. Headless UI and Tailwind CSS are two potent techniques that have become incredibly popular in recent years. In this article, we'll look at how Headless UI and Tailwind CSS combine to produce fluid user interfaces, adaptable UI elements, and effective development processes.

What is Headless UI

As was already established, the idea of a headless user interface (UI) separates the user interface (UI) from the data and logic that run behind it. It enables programmers to create a user interface (UI) that is adaptable and connectable to any backend or data source. Developers can construct a modular and scalable architecture using Headless UI, which offers a set of reusable UI components and a configurable API layer.

what is Tailwind CSS

Using the utility-first CSS framework Tailwind CSS, programmers can easily create unique user interfaces. Tailwind CSS offers a sizable utility class library in instead of relying on predefined styles and components. By combining these utility classes, programmers can construct unique styles and layouts that completely control the appearance of their application.

Let's modify the App.js file and get the output as shown below.

import { Dialog, Transition } from '@headlessui/react';
import React, { Fragment, useState } from 'react';

export default function MyModal() {
  let [isOpen, setIsOpen] = useState(true);

  function closeModal() {
    setIsOpen(false);
  }

  function openModal() {
    setIsOpen(true);
  }

  return (
