The template page. Copy into a new component and edit. This component is used as a placeholder for pages in the Site Map. The image is randomly chosen by the fine folks at lorem picsum.
This is an example of a Grid made from a map function. The Grid items contain a number to show their width in columns, or a dash to indicate "auto" layout, which will fill available space in a row.
The grid items are assigned refs during the map function, then those refs are used to animate the grid items in the useEffect hook.
