easy! go to the old editor (https://www.flipanim.com) then choose the colors for the gradient you want. then draw two lines of the gradient close to eachother. now, copy the frame two or three times. then download the file. next, go to the beta editor (https://www.flipanim.com/beta) and then upload the file in the editor. then enlarge it until you have a gradient. DONE!
