Invert Text Color on Mouse Hover
The goal is to invert the color of a text element while hovering over it with a black cursor. The effect should be similar to the following GIF:

To achieve this effect with CSS and JavaScript, we'll use a combination of techniques:
- Create a duplicate text layer: Duplicate the text element and position it directly on top of the original. Invert the color of the duplicate text layer to white.
- Use clip-path to reveal the top layer: Use a clip-path to define a circular area that will reveal the inverted text layer.
- Listen for mouse movements: When the user moves the cursor over the text, adjust the clip-path's position to match the cursor's movement.
Here's an example implementation:
<code class="javascript">var h = document.querySelector('h1'); var p = h.getBoundingClientRect(); var c = document.querySelector('.cursor'); 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'); };</code>
<code class="css">body { cursor: none; } 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%)); } .cursor { position: fixed; width: 40px; height: 40px; background: #000; border-radius: 50%; top: 0; left: 0; transform: translate(-50%, -50%); z-index: -2; }</code>
<code class="html"><h1 id="WORK">WORK</h1> <span class="cursor"></span></code>
By combining these techniques, we can create the desired text color inversion effect on mouse hover.
