var tl = gsap.timeline({ defaults: {duration: 1, ease: "elastic"} } );
tl.to(".open", {duration:0.2, scaleX:-1});
tl.to(".open", {duration:0.2, scaleX:1});
tl.play();
this way will get pushed into every child tween, I don't want that.
I want this ease will work on this animation, not in every child tween;
My english not well, do you understand?
