React Modals have solidified their presence in the modern web page, they provide new information asides from the information presented to the user on the main page without any need to refresh.

With their presence providing quality user experience, by making users focus on a particular information, usually deemed important by the creators of the website, there is a really high chance that you have seen or experienced a modal.

What is a React Modal

A React Modal is a component, a web element that displays information over the entire web page, which in turns disables the web page. When a modal is displayed, it usually places a dark overlay over the rest of the webpage excluding the overlay, this allows us to focus on the information the modal is passing through or to focus on performing the task, or completing the interaction the modal is requesting for.

Prerequisities

To make the most of this article, it is important that you have the following:

  • A basic understanding of HTML.
  • A basic understanding of CSS.
  • A basic understanding of React.
  • Node and it’s package manager, npm, Run the command node -v && npm -v to verify we have them installed, or install them from here.
  • Alternatively, we can use another package manager, Yarn.

What is Tailwind CSS

TailwindCSS refers to itself as a utility-first CSS framework, which has been designed to haelp ease the development process of creating web applications by creating custom-made styles that are available to developers via special classes, which are then added to the elements.

Creating our React project

To create a new react project, we go to our terminal, cd in the directory we want and then run this command npx create-react-app project-name.

cd Documents
npx create-react-app project-name

Installing Tailwind CSS

To have tailwindcss available in your project, cd into the project your created earlier

cd project-name

next run

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

Configuring your templates path

To configure your paths go to your tailwind.config.js, and edit your module.exports object, add the paths to your template files in your content array.

js
module.exports = {
content: ['./src/**/*.{js,jsx,ts,tsx}'],
theme: {
extend: {},
},
plugins: [],
};

Next add the Tailwind directives to your CSS

Add the tailwind directives in your ./src/index.css file.

@tailwind base;
@tailwind components;
@tailwind utilities;

After this we run our project

npm run start

You should this in your browser when you go to http://localhost:3000/.

React Bootstrap Modal

Tailwind modal: Creating your Tailwind CSS Modal

To create a tailwindcss modal using the template in the docs, we need to install a react library. To do that, we run this command :

jsx
// npm
npm install @headlessui/react
// Yarn
yarn add @headlessui/react

Simple Model

jsx
/* This example requires Tailwind CSS v2.0+ */
import { Fragment, useRef, useState } from 'react';
import { Dialog, Transition } from '@headlessui/react';
import { ExclamationIcon } from '@heroicons/react/outline';
export default function Example() {
const [open, setOpen] = useState(true);
const cancelButtonRef = useRef(null);
return (
<Transition.Root show={open} as={Fragment}>
<Dialog
as="div"
className="fixed z-10 inset-0 overflow-y-auto"
initialFocus={cancelButtonRef}
onClose={setOpen}
>
<div
className="flex items-end justify-center min-h-screen pt-4 px-4 pb-20 text-center sm:block
sm:p-0"
>
<Transition.Child
as={Fragment}
enter="ease-out duration-300"
enterFrom="opacity-0"
enterTo="opacity-100"
leave="ease-in duration-200"
leaveFrom="opacity-100"
leaveTo="opacity-0"
>
<Dialog.Overlay className="fixed inset-0 bg-gray-500 bg-opacity-75 transition-opacity" />
</Transition.Child>
{/* This element is to trick the browser into centering the modal contents. */}
<span className="hidden sm:inline-block sm:align-middle sm:h-screen" aria-hidden="true">
&#8203;
</span>
<Transition.Child
as={Fragment}
enter="ease-out duration-300"
enterFrom="opacity-0 translate-y-4 sm:translate-y-0 sm:scale-95"
enterTo="opacity-100 translate-y-0 sm:scale-100"
leave="ease-in duration-200"
leaveFrom="opacity-100 translate-y-0 sm:scale-100"
leaveTo="opacity-0 translate-y-4 sm:translate-y-0 sm:scale-95"

<div className="mt-2">

Are you sure you want to deactivate your account? All of your data will be
permanently removed. This action cannot be undone.

ref={cancelButtonRef}
>
Cancel
</button>
</div>
</div>
</Transition.Child>
</div>
</Dialog>
</Transition.Root>
);
}

Default React Bootstrap Modal

In the piece of code above we use the useState hook we get from react to create a piece of state that will be used to control whether or not the modal is opened. We use the Transition component is used to animate in and out the modal element and the Dialog component to communicate with the user, this component holds the information we want to pass to the user.

To make use of other templates by tailwindcss you have to get the pro version, get it here.

Conclusion

In this article we discussed installing tailwindcss and why we would need to install it. Next up we created a react bootstrap modal with the UI library.
