Staggered animation

CSS, Animation · Oct 11, 2021

Creates a staggered animation for the elements of a list.

  • Set opacity: 0 and transform: translateX(100%) to make list elements transparent and move them all the way to the right.
  • Specify the same transition properties for list elements, except transition-delay.
  • Use inline styles to specify a value for --i for each list element. This will in turn be used for transition-delay to create the stagger effect.
  • Use the :checked pseudo-class selector for the checkbox to style list elements. Set opacity to 1 and transform to translateX(0) to make them appear and slide into view.
