It is often convenient to use the shorthand property
animation
to set all animation properties at once.
/* Single animation */ animation-duration: 6s; animation-duration: 120ms; /* Multiple animations */ animation-duration: 1.64s, 15.22s; animation-duration: 10s, 35s, 230ms;
<time>
s
) or milliseconds (
ms
). The value must be positive or zero and the unit is required. A value of
0s
, which is the default value, indicates that no animation should occur.
注意：
Negative values are invalid, causing the declaration to be ignored. Some early, prefixed, implementations may consider them as identical to
0s
.
注意
: 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
