• : The animation reverses direction each cycle, with the first iteration being played forwards. The count to determine if a cycle is even or odd starts at one.

• : The animation reverses direction each cycle, with the first iteration being played backwards. The count to determine if a cycle is even or odd starts at one.> [!NOTE]> When you specify multiple comma-separated values on an animation-* property, they are applied to the animations in the order in which the {{cssxref(“animation-name”)}}s appear. For situations where the number of animations and animation-* property values do not match, see Setting multiple animation property values.> [!NOTE]> When creating CSS scroll-driven animations, specifying an animation-direction works as expected, for example reverse causes the animation to run in reverse over the course of the timeline’s progression. A value of alternate (combined with an {{cssxref(“animation-iteration-count”)}}) causes the animation to run forwards and backwards as the timeline is progressed.

• : The animation plays forwards each cycle. In other words, each time the animation cycles, the animation will reset to the beginning state and start over again. This is the default value.

Enter a raw string value for animation-direction

• : The animation plays backwards each cycle. In other words, each time the animation cycles, the animation will reset to the end state and start over again. Animation steps are performed backwards, and easing functions are also reversed. For example, an ease-in easing function becomes ease-out.

Enter a variable name to be used for animation-direction. It will be wrapped in var() and have -- prepended.
