animation-iteration-count
CSS
property sets the number of times an animation sequence should be played before stopping.
If multiple values are specified, each time the animation is played the next value in the list is used, cycling back to the first value after the last one is used.

It is often convenient to use the shorthand property
animation
to set all animation properties at once.
/* Keyword value */ animation-iteration-count: infinite; /* <number> values */ animation-iteration-count: 3; animation-iteration-count: 2.4; /* Multiple values */ animation-iteration-count: 2, 0, infinite;
animation-iteration-count
property is specified as one or more comma-separated values.
infinite
The animation will repeat forever.
<number>
1
by default. You may specify non-integer values to play part of an animation cycle: for example,
0.5
will play half of the animation cycle. Negative values are invalid.
注意
: When you specify multiple 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
