Hi BC, 

 

That seems a little odd so I'll need to investigate that some more, but here's a work around for now.

Yes, that's because the parent is display: flex and since you're converting between units (% to px), GSAP uses an invisible element that gets added temporarily (for measurement) but in that context a width: 100% isn't actually 100% due to the way the browser splits the spacing up in display: flex. I've added a workaround to the next release which you can preview at: https://assets.codepen.io/16327/gsap-latest-beta.min.js 

 

Better?

In the meantime, Blake's suggestion is great.
