Invert Text Color on Mouse Hover

This GIF demonstrates the desired effect:

It's possible to create this effect using CSS and JS. One method involves manipulating the clip-path of a duplicated text layer to reveal the inverted color on hover.

h1 {
  color: #000;
  display: inline-block;
  margin: 50px;
  text-align: center;
  position: relative;
}

h1:before {
  position: absolute;
  content: attr(data-text);
  color: #fff;
  background: #000;
  clip-path: circle(20px at var(--x, -100%) var(--y, -100%));
}

document.body.onmousemove = function(e) {
  // Adjust the cursor position
  c.style.left = e.clientX   'px';
  c.style.top = e.clientY   'px';

  // Adjust the clip-path
  h.style.setProperty('--x', (e.clientX - p.top)   'px');
  h.style.setProperty('--y', (e.clientY - p.left)   'px');
}

When the mouse moves, the script adjusts the clip-path to reveal more of the inverted text, creating the hover effect.
