Horizontal scroll appears briefly at beginning of tween

[Coop]

When you hit the "open" button you can see a 100% height and width panel slide in holding a div. At the bottom a horizontal scroll appears, then disappears at the end of the tween. Does anyone know how to suppress that scroll bar? it's causes what looks like a glitch. Thanks.

Hi and welcome to the forum.

 

I think you could set your overflow-x to hidden.

 

body {
  overflow-x:hidden;
}

Happy tweening.

Craig, that was it. Thank you!
