The "animation-direction" CSS Property

This property defines whether or not the animation should play in reverse on some or all cycles. The initial/default value is 'normal'.

Values for "animation-direction"

CSS Level	Value
CSS Animations Level 1	"<single-animation-direction>#", where <single-animation-direction> = "normal | reverse | alternate | alternate-reverse"

Notes

• So that animations work in major browsers, be sure to use the "animation-direction" property and the equivalent proprietary properties like "-moz-animation-direction", "-o-animation-direction", and "-webkit-animation-direction" ("-ms-animation-direction" is not needed).
