Parallax/magnetic mouse cursor

Is there a way I can get a parallax/magnetic mouse cursor to my squarespace website?
Like these website- https://www.minimist.ca/ and https://studiomaertens.com/about

I've posted this in Settings > Advanced > Header 

<script src="//ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

And this in Settings > Advanced > Footer

<script>

  $( ( ) => {
  
    $( 'body' ).prepend ( '<div class="cursor cursor-dot" style="left: 0px; top: 0px;">' );
  
    $( window ).mousemove ( function ( e ) {
    
      $( '.cursor' ).css ( {
      
        left: e.pageX,
        top: e.pageY
        
        } );
        
      } );
      
    $( window ).mousemove ( function ( e ) {
    
      $( 'a' ).on ( 'mouseenter', function ( ) {
        
        $( '.cursor' ).addClass ( 'active' );
        
        } );
        
      } );
      
    $( window ).mousemove ( function ( e ) {
    
      $( 'a' ).on ( 'mouseleave', function ( ) {
      
        $( '.cursor' ).removeClass ( 'active' );
        
        } );
        
      } );
      
    } );
    
  </script>

After doing that I've also pasted this in Design > Custom CSS
 

@media ( hover: none ) {

  .cursor {
  
    display: none !important;
    
    }
  }

* {

  cursor: none;
  
  }

.cursor {

  --size: 10px;
  
  height: var( --size );
  width: var( --size );
  
  border-radius: 50%;
  pointer-events: none;
  position: absolute;
  transform: translate( -50%, -50% );
  z-index: 99999999999;
  
  }

.cursor.cursor-dot {

  background: #ffffff; /* This defines the color of the cursor */
  mix-blend-mode: difference; /* This line is for the circle to invert Delete this line if you dont want the circle to invert */
  transition: width 0.8s, height 0.7s, background-color 0.9s;
  transition-timing-function: ease-out;
  
  }

.cursor-dot.active {

  --size: 60px;
  
  background-color: #ffffff;
  
  }

What I can't seem to get is the "finger pointing" on hover out of the way. And if it's possible, can any improvements be made so it only inverts when hovering on black and white?

Thank you very much.

Hi,

If you add the below to your CSS, that should do the trick for removing the "finger pointing" 🙂

a:hover {
 cursor: none;
}
