Divi Toolbox ➜ Extras ➜ Parallax Scrolling for Modules
This feature adds ten different scrolling speeds you can apply to any module to achieve beautiful and smooth parallax scrolling effect. The effect can be applied to any row, section, or – for the best results – any module.
Navigate to module Settings → Advanced tab → CSS ID & Classes → CSS Class, and add the preferred custom class. A negative value makes the element move more slowly than regular scrolling. A positive value makes it scroll more quickly than regular scrolling.
Please note: Scroll speed -2 (CSS class of scroll_speed_-2) is the default “smooth, relaxed” scroll speed for elements to scroll more slowly than the rest of the page. Use higher values with caution and preferably only for background elements.
See the demo page.
