Rallax.js is a dependency-free vanilla JavaScript library for adding parallax scrolling effects to HTML elements. It offers a simple API with speed control, start/stop toggling, conditional callbacks, and mobile width handling.
Use cases
- add parallax scrolling to a hero image
- create parallax effects without jQuery
- disable parallax on mobile screen widths
- change parallax speed dynamically while scrolling
- stop and start parallax based on scroll position
When to choose
- you want lightweight parallax with no dependencies
- you need programmatic control over parallax speed and state
- you want conditional parallax behavior via callbacks
When to avoid
- you need complex multi-layer scroll animation libraries
- you need a maintained project with recent updates
- you want scroll effects beyond parallax
