class Primer::Alpha::Layout

‘main` or `sidebar` comes first in code. The code order won’t affect the visual position.
Keyboard navigation follows the markup order. Decide carefully how the focus order should be be by deciding whether

`Layout` should always work in any screen size.
or it flows as a row, when `Main` and `Sidebar` are stacked vertically (e.g. on a mobile device).
`Layout` flows as both column, when there’s enough horizontal space to render both ‘Main` and `Sidebar`side-by-side (on a desktop of tablet device, per instance);
On smaller screens, `Layout` uses vertically stacked rows to display content.
`Layout` can be used for simple two-column pages, or it can be nested to provide flexible 3-column experiences.
`Layout` provides foundational patterns for responsive pages.
