@ppk A 2D zooming effect: https://css-tricks.com/zooming-images-in-a-grid-layout/ (not a common use case but not possible using flexbox)

Some grid pattern like I am explaining here: https://css-tricks.com/exploring-css-grids-implicit-grid-and-auto-placement-powers/#grid-patterns (in the "grid patterns" section). Some of them can be done using flexbox but would require more complex code

@ppk equal height rows based on the tallest one using grid-auto-rows: 1fr;

Same can be done for columns but it's more interesting for rows
