Create this stunning, high-end CSS border spotlight effect that makes your UI look expensive and interactive. Unlike a full glow, this dynamic border hover uses a precise, moving ring of light that follows the user's cursor, perfect for buttons, cards, and hero sections.
In this tutorial, you’ll learn how to build this minimal JavaScript spotlight effect the right way. We use a powerful combination of CSS masking and modern CSS properties to do the heavy lifting—JavaScript is only used to track the mouse position!
What You Will Learn & Build:
The Core Technique: How to use CSS masks and radial-gradient() to create a "cut-out" effect, isolating the glow to just the border.
Efficient JavaScript: How to use a single requestAnimationFrame loop to update CSS custom properties for buttery-smooth animation.
