react-parallax

A react component for simple parallax effect

Position calculation has changed in version 1.0.0 to get rid of some white space edge cases on large screens. I hope it does not break your current setup. In some cases you will have to adjust the strength value.

Install

npm install react-parallax --save

Demo

Default Usage

import { Parallax } from 'react-parallax';

const TheContainer = React.createClass({
  render: function () {
    return (
      <div>
	    <Parallax bgImage="assets/1.jpg" strength={400}>
		  <br/>
		  <h1> some content that is displayed above the bgImage </h1>
		</Parallax>
      </div>
    )
  }
});

Background Component

For more flexibility and styling purposes you can add a <Background></Background> section to your Parallax Container. Child nodes inside this Background will be positioned like the bgImage behind the other children. Compared to the bgImage there is no automatic scaling.

import { Parallax, Background } from 'react-parallax';

const TheContainer = React.createClass({
  render: function () {
    return (
      <div>
        <Parallax strength={300}>
		  <Background>
		    <img src="http://www.fillmurray.com/400/300"/>
			<div style={{
			   width: 800, 
			   height: 300, 
			   backgroundColor: '#450093'
			  }}></div>
			<img src="http://www.fillmurray.com/500/300"/>
		  </Background>
		  <h1>something else</h1>
		</Parallax>
      </div>
    )
  }
});
