Stack

Layout elements vertically and add space between them.

The container spans the whole line (because its width is auto). It uses a vertical flex under the hood. Items default to spread horizontally within the container.

Differences with a stock flex:

• It is vertical
• It sets a gap (16px by default)

Other settings and their default:

• justify: elements sit at the top by default (flex-start)
• align: elements fill the stack horizontally by default (stretch)
