Position

Position utilities set position (static, relative, absolute, fixed, sticky) and place absolute children with top-*, bottom-*, start-* and end-* at 0, 50 or 100. translate-middle, translate-middle-x and translate-middle-y centre an element on its point, which is how badges and status indicators sit on buttons and avatars.

1Edge positions

top-0, top-50, top-100 with start-0, start-50, start-100 place absolute children on a grid of nine points.
