Accessible modal dialog component for React.JS


To install the stable version:

npm install --save react-modal


  <h1>Modal Content</h1>


Styles are passed as an object with 2 keys, 'overlay' and 'content' like so

  overlay : {
    position          : 'fixed',
    top               : 0,
    left              : 0,
    right             : 0,
    bottom            : 0,
    backgroundColor   : 'rgba(255, 255, 255, 0.75)'
  content : {
    position                   : 'absolute',
    top                        : '40px',
    left                       : '40px',
    right                      : '40px',
    bottom                     : '40px',
    border                     : '1px solid #ccc',
    background                 : '#fff',
    overflow                   : 'auto',
    WebkitOverflowScrolling    : 'touch',
    borderRadius               : '4px',
    outline                    : 'none',
    padding                    : '20px'


Styles passed to the modal are merged in with the above defaults and applied to their respective elements. At this time, media queries will need to be handled by the consumer.

Using CSS Classes

If you prefer not to use inline styles or are unable to do so in your project, you can pass className and overlayClassName props to the Modal. If you do this then none of the default styles will apply and you will have full control over styling via CSS. There will be other classes which will be added depending on the state of the modal, such as --after-open and --before-close. These classes will be prefixed with the class names passed as props or with the default class names, for example with a className=mycompany-modal-class will produce a derivate class mycompany-modal-class--after-open.

You can also pass a portalClassName to change the wrapper's class (ReactModalPortal). This doesn't affect styling as no styles are applied to this element by default.

In addition you can also pass bodyClassName which will be the base for the class added to the body of the document.

Overriding styles globally

The default styles above are available on Modal.defaultStyles. Changes to this object will apply to all instances of the modal.


Inside an app:

var React = require('react');
var ReactDOM = require('react-dom');
var Modal = require('react-modal');

The app element allows you to specify the portion of your app that should be hidden (via aria-hidden)
to prevent assistive technologies such as screenreaders from reading content outside of the content of
your modal.  It can be specified in the following ways:

* element

* query selector - uses the first element found if you pass in a class.

var appElement = document.getElementById('your-app-element');

const customStyles = {
  content : {
    top                   : '50%',
    left                  : '50%',
    right                 : 'auto',
    bottom                : 'auto',
    marginRight           : '-50%',
    transform             : 'translate(-50%, -50%)'

var App = React.createClass({

  getInitialState: function() {
    return { modalIsOpen: false };

  openModal: function() {
    this.setState({modalIsOpen: true});

  afterOpenModal: function() {
    // references are now sync'd and can be accessed. = '#f00';

  closeModal: function() {
    this.setState({modalIsOpen: false});

  render: function() {
    return (
        <button onClick={this.openModal}>Open Modal</button>
          style={customStyles} >

          <h2 ref="subtitle">Hello</h2>
          <button onClick={this.closeModal}>close</button>
          <div>I am a modal</div>
            <input />
            <button>tab navigation</button>
            <button>the modal</button>

ReactDOM.render(<App/>, appElement);


When using React Test Utils with this library, here are some things to keep in mind:

  • You need to set isOpen={true} on the modal component for it to render its children.
  • You need to use the .portal property, as in ReactDOM.findDOMNode(renderedModal.portal) or TestUtils.scryRenderedDOMComponentsWithClass(Modal.portal, 'my-modal-class') to acquire a handle to the inner contents of your modal.

By default the modal is closed when clicking outside of it (the overlay area). If you want to prevent this behavior you can pass the 'shouldCloseOnOverlayClick' prop with 'false' value.


  <h1>Force Modal</h1>
  <p>Modal cannot be closed when clicking the overlay area</p>
  <button onClick={handleCloseFunc}>Close Modal...</button>
