The Skin on Scroll Effect template is an amazing feature to use when you have sections with different background colors.
The result is to get a smooth change on sections while scrolling by mixing the colors of each section.
You can find this page template in Page Attributes.
This template is available with the enhanced page builder of Impeka (WPBakery Page Builder + WPBakery Extension) and now also on Elementor with Impeka Widgets (Elementor + Elementor Extension)
