I am trying to make a sticky navbar go into a gradient and then come back to black on it’s fixed position, but when it moves it should smoothly merge into a gradient.
When I use the navbar to scroll down and turn from black to a gradient it works but when I go back up it pops into black instead of a smooth transition. how to go about this?
I want the gradient to have the same behavior as when I scroll down but when I scroll back up it dosen’t do the same.
