@PointC That's exactly what I tried just before making my last post, however, I was setting elements to .line ? Good to know I was on the right path though. Thank you for the other threads that have similar questions and I'm sorry for not finding them before posting.
@GreenSock Right on! That's amazing, thanks so much!
Only thing I don't fully understand is how this line of code works:
activeIndex = (activeIndex + 1) % containers.length;
Cheers guys you're the best!
