Sly

jQuery plugin for one-directional scrolling with item based navigation support. 12KB minified, 4.5KB gzipped.

Sly supports navigation with mouse wheel scrolling, scrollbar, pages bar, dragging the content, touch events, automated cycling, ... and has a powerful API.

That's all build around a custom highly optimized animation rendering with requestAnimationFrame, and GPU accelerated positioning (in browsers that support it).

Dependencies

Except jQuery 1.7+, there are no other dependencies. That means you don't need 200kB of jQuery-UI to use it.

Compatibility

Works everywhere, even in IE6+ abominations, but that is a complete accident :) IE 6-7 are not officially supported.

Mobile: Sly has a touch events support, but mobile is not tested. If you want to help with that, you are welcome!

Changelog

Sly upholds the Semantic Versioning Specification, and right now is in release candidate state. For more info, read the Roadmap section below.

Roadmap

All of the desired features have been implemented, and Sly is now in a release candidate state.

Maybe never, but it would be nice:

  • Dropping jQuery dependency.
