Right. I had some thought about this and I found a way out 馃檪 it was simpler than I thought and I鈥檓 happy it works. In the interaction panel, we were right about changing the initial position to -100% instead of 100%, but there was one extra step we were missing, which was to change the alignment of one of the parent divs. Originally, for the marquee to run left to right, .banner_component needed to be aligned to the right. By alining .banner_component to the left it makes possible for the marquee to run right to left with no gaps. Mystery solved. Thank you all for contributing
