The animation-name CSS property specifies the names of one or more @keyframes at-rules that describe the animation to apply to an element. Multiple @keyframe at-rules are specified as a comma-separated list of names. If the specified name does not match any @keyframe at-rule, no properties are animated.

Try it

It is often convenient to use the shorthand property animation to set all animation properties at once.


/* Single animation */
animation-name: none;
animation-name: test_05;
animation-name: -specific;
animation-name: sliding-vertically;

/* Multiple animations */
animation-name: test1, animation4;
animation-name: none, -moz-specific, sliding;

/* Global values */
animation-name: inherit;
animation-name: initial;
animation-name: revert;
animation-name: revert-layer;
animation-name: unset;



A special keyword denoting no keyframes. It can be used to deactivate an animation without changing the ordering of the other identifiers, or to deactivate animations coming from the cascade.


A name identifying the animation. This identifier is composed of a combination of case-sensitive letters a to z, numbers 0 to 9, underscores (_), and/or dashes (-). The first non-dash character must be a letter. Also, two dashes are forbidden at the beginning of the identifier. Furthermore, the identifier can't be none, unset, initial, or inherit.

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