Hello,
Apologies about the Inconveniences caused!
The Parallax Plugin used for the Parallax Functionality contains minimal documentation and also is slightly complicated. We are working on a Proper Documentation for the Parallax Plugin at the moment and it will be available by the end of this month for easier integration. Meanwhile, you can consider using the data-bottom-top="background-position:0px 0px;" data-top-bottom="background-position:0px -300px;" on the Parallax Section as an Example to apply a Parallax Effect on the Section. You can animate the CSS Properties of an Element/Section depending on the Horizontal Scrollbar Position. You use the HTML5 "data-" Attributes to define a Set of Styles. Like you can also use: data-bottom-top="background-position:0px 0px; background-color:#000". You can consider checking this cheatsheet for the available "data-" Attributes: https://ihatetomatoes.net/wp-content/uploads/2014/10/skrollr-cheatsheet-v02.png .
Hope this Helps!
