Grid Problem - why is there so much space?

[Psychopomp]

Hi,
I have a grid layout and for some reason there is too much space on the Mobile version of it. It’s not clear to me where this space is coming from and how to get rid of it, so that the column is only as high as the content is.
Maybe someone can help me out?

Hi,

you seem to have grid-template-rows applied to mobile, in a way that it creates two rows. Remove one minmax and it should work

Best regards,
