1. Start the layout in desktop mode, animation begins to play.
2. Scale down to mobile breakpoint, pause timeline and store a variable of the current timeline position.
3. Pick up the timeline in the next layout at the saved position.
4. Scale back up to original layout, perform the same function over again.
I understand that the timelines would have to be perfectly equal in length, and I intend them to be; identical animations for the components in each layout, but with some scaling and re-arranging applied to the mobile version.
