Part 3 - changing the render to implement the close icon state

Post.js

render() {
  /* ... */
  const { closeInverted, dragProgress } = this.state; // change the state
  
  return (
    /* same code */
    
    // this will add the invert class
    // when this.state.closeInverted is true
    <div
    className={cn('close', { invert: closeInverted })}
    onClick={() => navigateTo('home')}
  />
  /* same code */
  )
}
