lax.js

Simple & lightweight (<4kb gzipped) vanilla JavaScript library to create smooth & beautiful animations when you scroll. Lax.js 2.0 has been completely re-written with a focus on modularity and flexibility giving you more tools to create awesome animations. To implement lax you need to create at least one driver, to provide values for animations, as well as the element animation bindings. The easiest way to get started is to use presets via html classes. Multiple presets can be chained together and they can be customised to suit your needs. Use the preset explorer to explore effects and see a simple example here. To increase performance, lax.js indexes the list of elements to animate when the page loads. If you're using a library like React, Vue or EmberJS, it is likely that you are adding elements after the initial window.onload. Because of this you will need to call lax.addElements when you add components to the DOM that you want to animate.
