Subgrid Create a grid on a grid item which uses the grid tracks defined on the parent – for rows, columns or both. Slides & resources https://noti.st/rachelandrew

.grid { display: grid; grid-template-columns: repeat(9, 1fr); grid-template-rows: repeat(4, minmax(100px, auto)); } .item { grid-column: 2 / 7; grid-row: 2 / 4; display: grid; grid-template-columns: repeat(3, 1fr); grid-template-rows: repeat(3, 80px); } .subitem { grid-column: 2 / 4; grid-row: 1 / 4; } Slides & resources https://noti.st/rachelandrew

Line numbers start from 1 inside the subgrid. You position child items in the subgrid according to the subgrid line numbering, not those of the parent. Slides & resources https://noti.st/rachelandrew

Line names on the parent are passed into the subgrid. If you have named lines on the parent grid they will be passed into the subgrid and added to any names defined there. Slides & resources https://noti.st/rachelandrew
