I am just not sure if x and y properties are supposed to be relative to transformOrigin.


Let's say I have a simple div, width 200px, height 200px.


If I am right, by default, transformOrigin is set to "50% 50% 0".


So if I rotate my div, the rotation is relative to its center. Fine.


But if I set x and y properties of my div (with TweenMax.set()), the position is always relative to its top left corner, and not to its transformOrigin.


1) is it the expected behaviour ?


2) if yes, is there a way to change the origin point for x and y properties ? Without having to set margin-left : -100px and margin-top : -100px

Hello Clemorphy, and Welcome to the GreenSock forum!


When i animate x and y .. i do not see how the transform-origin changes. It is still 50% 50% like when it is rotating


See the Pen ORLAmW by jonathan (@jonathan) on CodePen


Now i can see how transform-origin would change if you were doing a whole mess of rotations within nested elements. But the behavior should be the same whether it is animated with CSS transitions / animations or via JS. ;)


If you are still having an issue, please provide a codepen demo example showing your issue so we can help you better.
