Stacked card listing on version 15 of CSS-Tricks

On mobile, the cards stack on top of each other.

A series of post teasers, visually styled to look like cards, with those later in the list overlaying part of the bottom of their preceding card.

Which has also been confusing for some folks. The thinking is: cards are always excerpts. The stacking (and thus hiding of some text) says: click/tap this to keep reading it.
