CSS3 animation not working in safari - css

Question

I have a bit of CSS3 animation which works perfectly in all the browser which support CSS3 except safari. Weird isn't it? Ok here's my code:
HTML
<div class="right">
<div class="key-arm"><img src="images/landing/key-arm.png" alt="arm" /></div>
</div>
CSS
.landing .board .right {
width: 291px;
height: 279px;
background: url('../images/landing/key-pnl.png');
bottom: 16px;
right: 250px;
position: absolute;
}
.landing .board .right .key-arm {
position: absolute;
left: 44px;
top: 18px;
width: 41px;
height: 120px;
}
/*=== Key Arm Animation ===*/
#-webkit-keyframes keyarm {
0% { -webkit-transform: rotate(0deg); }
5% { -webkit-transform: rotate(-14deg); }
10% { -webkit-transform: rotate(0deg); }
}
#-moz-keyframes keyarm {
0% { -moz-transform: rotate(0deg); }
5% { -moz-transform: rotate(-14deg); }
10% { -moz-transform: rotate(0deg); }
}
#-ms-keyframes keyarm {
0% { -ms-transform: rotate(0deg); }
5% { -ms-transform: rotate(-14deg); }
10% { -ms-transform: rotate(0deg); }
}
#-o-keyframes keyarm {
0% { -o-transform: rotate(0deg); }
5% { -o-transform: rotate(-14deg); }
10% { -o-transform: rotate(0deg); }
}
#keyframes keyarm{
0% { transform: rotate(0deg); }
5% { transform: rotate(-14deg); }
10% { transform: rotate(0deg); }
}
.right .key-arm{
-webkit-transform-origin: 12px 105px;
-moz-transform-origin: 12px 105px;
-ms-transform-origin: 12px 105px;
-o-transform-origin: 12px 105px;
transform-origin: 12px 105px;
-webkit-animation: keyarm 8s ease-in-out 0s infinite;
-moz-animation: keyarm 8s ease-in-out 4s infinite;
-ms-animation: keyarm 8s ease-in-out 4s infinite;
-o-animation: keyarm 8s ease-in-out 4s infinite;
animation: keyarm 8s ease-in-out 0s infinite;
}
Ok this doesn't work in Safari as I said, there's no movement whatsoever.
Also, still and only in Safari, the key-arm div shows only if you resize the screen! It's there in the DOM but for some reason it doesn't show up!
What am I doing wrong?
Thanks

UPDATE: Ok from your answers I got that #keyframes is not supported on Safari 4. It's strange because on the same page I have an animation that works using #keyframes!
here's the CSS code:
.board .rays{
background: url("../images/landing/rays.gif") no-repeat 0 0 red;
height: 381px;
left: 251px;
opacity: 1;
top: 80px;
width: 408px;
position: absolute;
}
.board .bottle{
background: url("../images/landing/bottle.gif") no-repeat 0 0 lime;
bottom: 30px;
height: 405px;
left: 276px;
width: 357px;
z-index: 1;
position:absolute;
}
/*=== Rays Animation ===*/
#-webkit-keyframes rays{
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(360deg); }
}
#-moz-keyframes rays{
0% { -moz-transform: rotate(0deg); }
100% { -moz-transform: rotate(360deg); }
}
.board .rays{
-webkit-animation: rays 40s linear 0s infinite;
-moz-animation: rays 40s linear 0s infinite;
animation: rays 40s linear 0s infinite;
}
And the html:
<div class="board">
<div class="rays"></div>
<div class="bottle"></div>
</div>
Try it yourself in jsFiddle (if you have Safari 4) and you'll see

Answer 1

Found the solution. In Safari when you use Keyframes you need to use the whole percentage:
this won't work:
#-webkit-keyframes keyarm {
0% { -webkit-transform: rotate(0deg); }
5% { -webkit-transform: rotate(-14deg); }
10% { -webkit-transform: rotate(0deg); }
}
this will:
#-webkit-keyframes keyarm {
0% { -webkit-transform: rotate(0deg); }
5% { -webkit-transform: rotate(-14deg); }
10% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(0deg); }
}
Don't know why but that's the way Safari works! :)

Answer 2

I was having troubles with CSS3 animation working in Safari 6, but not in Safari 4 (4.0.5).
It appears that the shorthand notation will not work in Safari 4.
So this won't work :
-webkit-animation: rays 40s linear forwards;
But this will work :
-webkit-animation-name: rays;
-webkit-animation-duration: 40s;
-webkit-animation-iteration-count: 1;
-webkit-animation-timing-function: linear;
-webkit-animation-fill-mode: forwards;

Answer 3

In situations where you're trying to animate transform on something as soon as it's injected into the DOM, I've had to add a very brief delay, like this:
animation: rays 40s linear 0.01s infinite;

Answer 4

I struggled with an animation working in Safari 14 (14.1.2), but not in Safari 15, and thought I'd add my findings here.
This css is part of the scrolling text loop here.
#banner-loop {
white-space: nowrap;
animation: loop-anim 5s linear infinite;
}
#keyframes loop-anim {
0% { margin-left: 0; }
100% { margin-left: -50%; }
}
I noticed that the animation "played", but didn't animate.
I tried the solutions from the other answers here, but nothing worked (including having the -webkit prefix). In the end the problem was solved by changing the start keyframe value to 0% instead of 0.
It looks like Safari can't handle the unit-less 0 shorthand in this case.

Answer 5

Try force quitting Safari and/or rebooting your phone (assuming you're on a phone).
Just had animations fail in Safari 15 for no apparent reason - very simple ones such as opacity and simple keyframes.
I noticed my phone was doing that thing where the white homescreen indicator gets permanently stuck on the long side of the phone even when holding it vertically. A reboot is usually needed to fix that.
Turns out rebooting also fixed the animations in Safari.
Another thing to remember with Safari is that low battery mode can affect animations and make them less smooth (and prevent muted autoplay videos from auto playing).

Answer 6

#-webkit-keyframes { <- let this symbol to the same line
} - >
This works on iphone 3 ios 6.1.6
with -webkit- prefix on transform and animation
