Provides settings like orientation, scale, delay, and maxTransition for fine-tuning parallax intensity and behavior to match design needs.
Easy to initialize with minimal code—often just a few lines—focusing on developer experience and quick setup without bloat.
The delay parameter is documented to cause issues on iOS devices, limiting reliability for mobile-heavy projects without workarounds.
