A super easy trick that makes your website and prototype fun to use.
This trick will work for any of the Anima plugins, in Sketch, Adobe XD, or Figma.
Create two identical shapes that will represent each state of the button: Hover On and Hover Off
Choose the color for each state: Blue for when the hover is OFF, and Dark Blue for when the hover is ON
Stack the two shapes on top of each other with the Dark Blue at the bottom and group them together.
Select the shape on the top, "hover off", go to Smart Layers in Anima panel and select Hover Effect
From the Hover Effects presets, select Fade Out and Save. This setting will make the Blue button disappear when the mouse is over it and show the Darker one under it.
