Pretty fun! I got stuck at level 26, my solution looks visually correct but the next button won't activate:
grid-template-rows: repeat(4, 10px) 1fr; grid-template-rows: repeat(4, 10px) 1fr;With your approach you need 4 rows with the size of 50px/4=12.5px:
`grid-template-rows: repeat(4, 12.5px) 1fr;`
However, you can also "size" first (or any other "nice" number) of rows and insert zero-sized fluff areas:
`grid-template-rows: 50px repeat(3, 0px) 1fr;`
12.5px
