Usage

Add the <ModalProvider> component near the top of your application's tree.

import React, { Component } from 'react'
import { ModalProvider } from 'styled-react-modal'
...

export default class App extends Component {
  render () {
    return (
      <ThemeProvider theme={theme}>
        <ModalProvider>
          <FancyModalButton />
        </ModalProvider>
      </ThemeProvider>
    )
  }
}

Use the <Modal> component.

import Modal from 'styled-react-modal'
...

const StyledModal = Modal.styled`
  width: 20rem;
  height: 20rem;
  display: flex;
  align-items: center;
  justify-content: center;
  background-color: ${props => props.theme.colors.white};
`

class FancyModalButton extends Component {
  constructor (props) {
    super(props)

    this.state = {
      isOpen: false,
    }

    this.toggleModal = this.toggleModal.bind(this)
  }

  toggleModal (e) {
    this.setState({ isOpen: !this.state.isOpen })
  }

  render () {
    return (
      <div>
        <button onClick={this.toggleModal}>Click me</button>
        <StyledModal
          isOpen={this.state.isOpen}
          onBackgroundClick={this.toggleModal}
          onEscapeKeydown={this.toggleModal}>
          <span>I am a modal!</span>
          <button onClick={this.toggleModal}>Close me</button>
        </StyledModal>
      </div>
