How to make an element appear on a specific second ?
i have a circle_A that start from 0 second/0px and move a distance of 200px
then circle_B appear at 2 second/200px
problem is that Circle_B appear even at 0 second/200px ( which i dont know how to solve that)
So how to make Circle_B appear at 2second on the timeline? ( without using opacity )
