animation-name - CSS: Cascading Style Sheets 编辑

The animation-name CSS property specifies the names of one or more @keyframes at-rules describing the animation or animations to apply to the element.

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

Syntax

/* 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: initial
animation-name: inherit
animation-name: unset

Values

none

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.

<custom-ident>

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 will be assigned to the animations specified in the animation-name property in different ways depending on how many there are. For more information, see Setting multiple animation property values.
