Stack
Layout elements vertically, add some space between elements.
A thin abstraction over a flex: by default, it only adds a gap and makes the flex vertical. The container spans the whole line.
gap
: defaults to 16px.justify
: defaults to browser's default: flex-start (elements sit at the top),align
: defaults to browser's default: stretch (stretch elements along the cross axis, spreading the whole width)
Like any div with the default display:block, the stack itself occupies the full width.
