In the Sj Tni v1 template we have implemented the animation engine based on the scrollReveal.js script. This script makes creating elements onscroll animations very simple to define.
Thanks to this script you can describe an animation using natural language.
Description of the animation is placed in the data-scroll-reveal attribute:
<!-- These 3 lines are equivalent --> <div data-scroll-reveal="enter left and move 50px over 1.33s"> Foo </div> <div data-scroll-reveal="enter from the bottom after 1s"> Bar </div> <div data-scroll-reveal="wait 2.5s and then ease-in-out 100px"> Baz </div>
The full description of the syntax is available on the project documentation page
