The Background Gradient Hover Effect is a simple and fun way of changing the gradient background color in Webflow using mouse hover. Please note that this technique will not work in Firefox. This technique is a native Webflow interaction that uses just a single line of CSS code to control the pointer events and the location of the blur and its surrounding effects. Kevin Haag has created a Webflow cloneable that demonstrates this technique and has categorized it under the categories of Background, Gradient, Hover, and CSS. By using the Background Gradient Hover Effect, you can easily add a dynamic and interactive hover effect to your Webflow projects.
