Please add a visual examples to play with "Grid Auto Rows" online

[KostiantynO]

1. Is it possible to add online-configurable visual example for grid-auto-rows ?

Intention: I want to select 4 available tailwind classes, and see the difference for 1,2,3 rows and 1,2,3 columns.

This is to build an Image gallery using grid with 3 columns and unlimited auto-added rows.
I do not want to set specific width and height on images if that is possible.
I want image placeholders to be rendered inside of the grid with auto-determined fixed size, then request for Next.js Image would fire a get request for the right image size from srcset.
Is it possible?
