Replace Your Animated GIFs with SVGs – Frontend Masters Blog

Animated SVGs can replace heavy animated GIFs with dramatically smaller file sizes while maintaining infinite scalability. The technique involves embedding CSS animations directly within SVG files, which continue to work when loaded via img tags or background-image properties. A zombie accordion example demonstrates 98% file size reduction compared to GIF equivalent. Some media queries work within SVGs, but limitations include no hover effects, no prefers-reduced-motion support, and restricted JavaScript execution.
