Thanks Cassie
I think the part I'm struggling with is I'd normally have list items for a slider either stacked horizontally or vertically (depending on the direction of the slider) and hide them using overflow hidden, then scroll them into view using a transform. The big difference I guess in this case is that while the image slides in from the right as I'm use to, the text is coming from a vertical position. I guess I'm trying to figure out how my list of slides would have to stack - like how would they appear if the overflow wasn't hidden - as each slide seems to contain element that come into view but from different directions.
Even as I write this I think it's difficult to explain. Does this make any sense?
