Pitfalls of Card UIs
I’m currently in the process of rolling out yet another Card UI. Since Pinterest, the end-state of every list view with decent imagery is to become a Card UI. But thar be dragons! I’m here to share some of the pitfalls Paravel have encountered building Card UIs over the years.
Invention Cards 3.0: Stories
