Note:When you specify multiple comma-separated values on ananimation-* property, they are applied to the animations in the order in which theanimation-names appear. For situations where the number of animations andanimation-* property values do not match, seeSetting multiple animation property values.

Note:When creatingCSS scroll-driven animations, specifying ananimation-iteration-count causes the animation to repeat that number of times over the course of the timeline's progression. If ananimation-iteration-count is not provided, the animation will only occur once.infinite is a valid value for scroll-driven animations, but it results in an animation that doesn't work.
