Description
SmartParallax adds true scroll-linked parallax effects to WordPress — designed for performance, not gimmicks.
Unlike many animation plugins, SmartParallax does not run time-based animations.
All motion is directly tied to the user’s scroll position.
If the user doesn’t scroll, nothing moves.
This approach results in excellent performance, smooth motion and stable Core Web Vitals — even on mobile devices.
You don’t write JavaScript.
You don’t configure timelines.
You simply add a CSS class to a block, image or section — and the parallax scroll effect works instantly.
SmartParallax uses a small, dependency-free JavaScript engine and GPU-accelerated transforms.
There is no jQuery, no frameworks and no heavy animation libraries involved.
The plugin works out of the box with:
Gutenberg (Block Editor), Full Site Editing (FSE), Elementor, Bricks, Divi, Oxygen, WPBakery and most modern WordPress themes.
Perfect for:
- Parallax scroll sections
- Scroll animations in Elementor
- Gutenberg scroll effects
- Background parallax images
- Lightweight animation on scroll
