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
col-start col-end col-start col-end Slides & resources https://noti.st/rachelandrew
.grid { display: grid; grid-template-columns:1fr 1fr 1fr [col-start] 1fr 1fr 1fr [col-end] 1fr 1fr 1fr; grid-template-rows: repeat(4, minmax(100px, auto)); } .item { grid-column: 2 / 7; grid-row: 2 / 4; display: grid; grid-template-columns: subgrid; grid-template-rows: subgrid; } .subitem { grid-column: col-start / col-end; grid-row: 1 / 3; } Slides & resources https://noti.st/rachelandrew
You can add named lines to the subgrid. Line names are added after the subgrid keyword. Slides & resources https://noti.st/rachelandrew

.wrapper { display: grid; gap: 10px; grid-template-columns: repeat(5, 1fr); /* 5 explicit rows */ grid-template-rows: repeat(5, minmax(100px, auto)); } .fullheight { background-color: rgb(209,54,114); grid-row: 1 / -1; } Slides & resources https://noti.st/rachelandrew

We were all pretty excited when CSS grid layout subgrid landed in Firefox, but in the long wait for it to make it to Chrome, it’s a value that has had little attention in the past year. However, it is on the way, and in this talk, I’ll show you some interesting patterns that it enables, so you’ll be ready to take advantage of these new layout possibilities.
