Help with Story Card Page Transition

Morning all,

I’m trying to understand how the page transition on this website (BT Annual Review 2020) can be achieved in Webflow. Using Chrome Dev Tools I can see that the new page appears to start its transition from the card and expand out(!?)

Any help would be greatly appreciated.

Cheers!
Chris
