Hi @TechTailor, as of right now, you can’t manipulate box-shadow with Webflow interactions (Mouse click tap). If applicable for your use case, you could realize a transition on hover.
These are just different attributes of the objects’ states. Select an object with the shadow that needs to be different on mouse hover, change state of the object at the top right corner in the designer to be “hover”, modify your shadow. Then in the “none” state modify transition parameter (at the bottom of the style bar) for the element so that shadow change is smooth. That’s it.
