skrollr is a stand-alone, dependency-free JavaScript library for parallax scrolling and scroll-driven CSS animations on desktop and mobile browsers. Animations are defined declaratively via HTML data attributes and keyframes rather than JavaScript code.
Use cases
- add parallax scrolling effects to a website
- animate CSS properties based on scroll position
- create scroll-driven animations without jQuery
- build parallax pages that work on mobile browsers
- define scroll animations declaratively in HTML
- animate colors, transforms, and numeric CSS properties on scroll
When to choose
- you need a tiny (~12k) dependency-free scroll animation library for legacy browser targets
- you want designer-friendly animations defined in plain HTML/CSS with no JavaScript skills
- you are maintaining an existing site already built with skrollr
When to avoid
- you are starting a new production project - the library has been unmaintained since 2014 and may break in modern browsers, especially mobile
- you need modern scroll animation features - use native CSS scroll-driven animations or actively maintained libraries instead
- you require guaranteed compatibility with current mobile browsers, which the author explicitly warns about
