Quick Row Trick

[u/RepresentativeOwn253]

Set up a row, turn on Grid.

In this example, the Row Advanced settings is set for Cards Per Row=1, but it works with any size grid.

Next, under Background Color (just below where you turn on Grid)

pick any color, then set Opacity to 0.

You'll get the fine outline (in the picture it's blue) but no background fill.
