2 CSS and JavaScript Halloween Examples

This “Halloween in CSS and JavaScript” collection demonstrates how to create a spooky yet stylish atmosphere using the power of front-end technologies. The main focus is on CSS animations to simulate moving ghosts, flickering lights, and cyclical textures. You’ll see how SVG filters (FeColorMatrix, FeDisplacement) are combined with JS libraries like GSAP Timeline to create glitch effects, screen distortion, and a truly “spooky” atmosphere. This is the perfect resource for mastering complex, performant visual effects.
