In the project's repo the react-redux app is set with CSS in JS files. Now I'm supposed to animate pictures with mouse hover just like this website : https://www.madwell.com/

The component was initially a functional component and I have changed that to a class based component as follows:

```

class BannerContainer extends React.Component{

  constructor(props){

    super(props);

    this.state = {

      x: 0,

      y: 0

    };



    this.handleMouseMove = this.handleMouseMove.bind(this);

  }



  componentDidMount(){

    window.addEventListener("mousemove", this.handleMouseMove);

  }



  componentWillUnmount(){

    window.removeEventListener('mousemove', this.handleMouseMove);

  }



  handleMouseMove({ x, y }){

    this.setState({

      x : x / window.innerWidth,

      y : y / window.innerHeight

    })

  }



  render(){

  const { banner = {} } = this.props;



  const {

    title = '&nbsp;<br>&nbsp;',

    text = '&nbsp;<br>&nbsp;',

    image__google_350x80 = '',

    image__app_350x80 = '',

    image__bg1_1166x1878 = '',

    image__bg2_961x1782 = '',

    image__curve_730x151 = ''

  } = banner;



  return (

    <Container>

      <BGPatch>

        {console.log(this.state.x , this.state.y)}

        <img src={'/images/bg_purple.jpg'} alt="" />

      </BGPatch>

```

In this example I am able to get listen to the mouse-move event and and get the x & y coordinates accordingly. But now I have to use react-spring library to implement it so how do I do that? Also the CSS should be written in separate JS file for each component where as in react-spring example they directly modify the opacity or trasform in the Spring component directly as well which is what I don't want

the spring component example given on their docs

<Spring from={{ opacity: 0 }} to={{ opacity: 1 }}>

  {props => <div style={props}>hello</div>}

</Spring>

Parallaxing effects are relatively easy to do if you have mouse coordinates, here's an example with a similar effect: https://twitter.com/0xca0a/status/1058505720574959616

It uses hooks, but the same thing applies to a regular spring. Though this is probably a good example even, because it doesn't re-render the component on mousemove, which is very fast. You wouldn't use rotates in your case, translates i guess, but the point is, you receive x/y and use it to interpolate your images into position.

EDIT:
I've forked the example, this version uses translates: https://codesandbox.io/embed/r5x34869vq
