A free video course on CSS Grid.

CSS Grid is a free video course by Wes Bos: 25 videos, about 4 hours, from grid fundamentals to real layouts. It was sponsored by Mozilla Firefox and uses Firefox's grid dev tools.
It covers implicit and explicit tracks, auto-fit and auto-fill, minmax(), template areas, named lines, alignment and Grid vs Flexbox. Each exercise comes with starter files and finished solutions, and every video has English captions.
