Units
Things worth remembering
- auto-fill keeps empty tracks, auto-fit collapses them. Use auto-fit when you want remaining items to stretch.
- minmax(0, 1fr) instead of 1fr prevents grid children with long content from overflowing their track.
- Line numbers count gaps, not tracks. grid-column: 1 / -1 always spans the full row regardless of column count.
