Approach 1: Using React Usable Funtional Components
React Modal Component involves a reusable component that can be toggled on and off due to user interaction. By adding required css and open-close funtions we will create React Modal Component.
To use the modal component in your React application, you first need to import it. This can be done using the import statement. You can import react modal from the ‘react-modal’ package or you can create your own modal.
Example: Define Modal Component and use with given Open state and onClose attribute. Define useState variable and open close funtion to show and hide the modal.
JavaScript // App.js import React from "react"; import Modal from "./Modal"; export default function App() { const [open, setOpen] = React.useState(false); const handleClose = () => { setOpen(false); }; const handleOpen = () => { setOpen(true); }; return ( <div style={{ textAlign: "center", display: "block", padding: 30, margin: "auto", }} > <h1 style={{ color: "green" }}> GeeksforGeeks </h1> <h4>Modal Component in ReactJS?</h4> <button type="button" onClick={handleOpen}> Click Me to Open Modal </button> <Modal isOpen={open} onClose={handleClose}> <> <h1>GFG</h1> <h3>A computer science portal!</h3> </> </Modal> </div> ); } // Modal.js import React from "react"; const Modal = ({ isOpen, onClose, children }) => { if (!isOpen) return null; return ( <div onClick={onClose} style={{ position: "fixed", top: 0, left: 0, width: "100%", height: "100%", background: "rgba(0, 0, 0, 0.5)", display: "flex", alignItems: "center", justifyContent: "center", }} > <div style={{ background: "white", height: 150, width: 240, margin: "auto", padding: "2%", border: "2px solid #000", borderRadius: "10px", boxShadow: "2px solid black", }} > {children} </div> </div> ); }; export default Modal;
Step to Run Application: Run the application using the following command from the root directory of the project.
npm start
Output: Now open your browser and go to http://localhost:3000/, you will see the following output.

Approach 2: Using MUI Modal Component in React
We can use the MUI modal component by simply installing the MUI module and importing the modal component as done in the example below.
Step to Install MUI: Install the material-ui modules using the following command.
npm i @material-ui/core
Dependencies list after installing material UI
"dependencies": { "@material-ui/core": "^4.12.4", "@testing-library/jest-dom": "^5.17.0", "@testing-library/react": "^13.4.0", "@testing-library/user-event": "^13.5.0", "react": "^18.2.0", "react-dom": "^18.2.0", "react-scripts": "5.0.1", "web-vitals": "^2.1.4" } Example: Open and close modal component using a button by defining handleOpen and handleClose functions with a useState variable.
JavaScript import React from "react"; import Modal from "@material-ui/core/Modal"; export default function App() { const [open, setOpen] = React.useState(false); const handleClose = () => { setOpen(false); }; const handleOpen = () => { setOpen(true); }; return ( <div style={{ textAlign: "center", display: "block", padding: 30, margin: "auto", }} > <h1 style={{ color: "green" }}> GeeksforGeeks </h1> <h4>Modal Component in ReactJS?</h4> <button type="button" onClick={handleOpen}> Click Me to Open Modal </button> <Modal onClose={handleClose} open={open} style={{ position: "absolute", border: "2px solid #000", backgroundColor: "lightgray", boxShadow: "2px solid black", height: 150, width: 240, margin: "auto", padding: "2%", color: "white", }} > <> <h2>GFG</h2> <p>A computer science portal!</p> </> </Modal> </div> ); }
Step to Run Application: Run the application using the following command from the root directory of the project.
npm start
Output: Now open your browser and go to http://localhost:3000/, you will see the following output.
