CSS Grid is horrendous to debug once it gets complex and you can’t rely on document flow any more, things can be placed anywhere which might seem big and clever but a few nested grids + the cascade and you’re quite frankly screwed. If you really must use CSS grid I say use it for the main layout and nothing else, then at least future you has a chance. Also this is more complex than using negative margins ever was.
