Toast Stack Arrival

Three toasts arrive one by one, and each newcomer pushes the earlier ones up, smaller and dimmer into a depth stack. Status icons pop as each toast lands; the rear toasts give way a beat later.

Also known as: sonner toast animation css, stacked toast notifications, toast stack css, notification stack animation.

Customizing this snippet

  • Color: set --kfa-color on the element or a parent. Currently previewing #3b82f6.
  • Base size: set --kfa-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
  • Speed: change the duration on the transition or animation shorthand. Staggered delays are relative, so they keep their rhythm.
  • Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
