Divi Toolbox ➜ Mobile ➜ Enable Parallax Background Effect on Mobile
The Divi Toolbox adds the option to enable the parallax background effect when viewed on mobile device.
How to use it:
Navigate to Section, Row or Module Setting ➜ Advanced tab ➜ CSS ID & Classes ➜ CSS Class and add a custom class of: dtb-mobile-parallax
Add a background image and make sure the Parallax Effect is enabled. Both the “CSS Parallax” and the “True Parallax” option will be displayed as “True Parallax”. Please note it’s best to use this effect only sparingly as it may cause your page to be jumpy, especially on content- and image-heavy pages.
