EPIC HUMBLEBRAG

const w = window.innerWidth

const getPercentX = x => Math.round(x / w * 360)

const mouse$ = Rx.Observable
  .fromEvent(document, 'mousemove')
  .map(({ clientX }) => {
    const percentX = getPercentX(clientX)
    
    return {
      xStart: percentX,
      xEnd:   percentX + 120
    }
  });


RxCSS({grad: mouse$})
:root {
  --grad-xStart: 280;
  --grad-xEnd:   40;
  --grad-start:  hsl(var(--grad-xStart), 100%, 75%);
  --grad-end:    hsl(var(--grad-xEnd), 100%, 50%);
}

p {
  &::before, &::after {
    position:  absolute;
    display:   block;
    width:     100%;
    padding:   5px;
    font-size: 12px;
    color:     #fff;
  }
    
  &::before {
    content: 'hsl(' var(--grad-xStart) ', 100%, 75%)';
    bottom:  100%; 
  }
  &::after {
    content: 'hsl(' var(--grad-xEnd) ', 100%, 50%)';
    top:     100%;
  }
}
