Chrome 3+, Safari 3.1+
Notes
• WebKit supports this property as
-webkit-animation-direction
.
• If the
animation-direction
is
alternate
, the timing function will also alternate
if appropriate.
• Firefox 3.7 pre-releases show support for CSS transitions which are very related to
CSS animation. It is quite likely that a form of this property using the
-moz
prefix
may be supported in a Firefox browser by the time you read this.
animation-duration
This property is used to define the time it takes one iteration of an animation to play.
Syntax
animation-duration:
time
[,
time
]*
where
time
is a valid time value like 5s or 3500ms. The initial value of time is 0, meaning no
animation plays.
