- How it is used
- Organizes page content into responsive, visually related sections before typography, color, and other visual treatments.
- How deep it goes
- Explains grid dimensions, spans, and responsive layout decisions, but does not detail CSS Grid syntax or implementation internals.
- Examples
- Uses four-column spans, homepage rows with changing column counts, and a 12-column travel-site layout adapted to tablet and mobile.
- What you can do after
- Apply it via CSS Grid to organize responsive page sections, align components, and simplify layouts for smaller screens.

- How it is used
- Organizes overall page layouts across rows and columns, with Flexbox handling one-dimensional groups inside them.
- How deep it goes
- Defines containers and items, demonstrates display: grid, and applies a three-column centering layout; row and column configuration is deferred.
- Examples
