Modern Scroll Shadows Using Scroll-Driven Animations

CSS masking and animation techniques are advancing, enabling more sophisticated scrolling effects. A new method uses animation-timeline and custom properties to fade out edges of scrollable elements, particularly for horizontal content on mobile devices. This approach combines CSS masks, linear gradients, and custom property animation to create a fade effect compatible with various backgrounds. The technique offers a JavaScript-free solution that degrades gracefully in unsupported browsers, demonstrating the expanding capabilities of modern CSS despite limited current support.
