CSS animation rules disappear in Firefox resulting in no animation - css

Question

I've just set up a few css animations and everything is running smoothly in Chrome and Safari however Firefox doesn't appear to be playing nice.
The following code:
#clock-animation .hour {
-webkit-animation: anti-spin 30s infinite;
animation: anti-spin 30s infinte;
-webkit-transform-origin: 50% 50%;
transform-origin: 50% 50%;
}
Appears to be displaying as:
#clock-animation .hour {
transform-origin: 50% 50% 0;
}
When viewed in Firebug and consequently the animation isn't playing.
I'm a tad confused as to why this is and nothing appears to be fixing it.
Here are the keyframes used too:
#-webkit-keyframes anti-spin {
100% {
-webkit-transform: rotate(-360deg);
}
}
#keyframes anti-spin {
100% {
transform: rotate(-360deg);
}
}
According to http://shouldiprefix.com/ the -moz prefix isn't needed for keyframes, animation or transform. Nor is the -webkit which is only needed for Chrome and Safari. Any help would be great.
Edit: Just to mention that the IDs and classes are part of an inline SVG file. I'm not sure if that is relevant or not?
Edit: Heres a link to a demo https://jsfiddle.net/0Lha6dfg/ (Works fine in Chrome / Safari but not in FF (36.0.1))

Answer 1

Make sure to write out your animation shorthand property in full, do not skip properties. Shorthand format from w3 specs:
div {
animation-name: example;
animation-duration: 5s;
animation-timing-function: linear;
animation-delay: 2s;
animation-iteration-count: infinite;
animation-direction: alternate;
}
Becomes:
div {
animation: example 5s linear 2s infinite alternate;
}
So in your example add the animation-delay:
animation: anti-spin 30s linear infinite;
Should be:
animation: anti-spin 30s linear 0s infinite;
Also watch out for typos, in some places you have "infinte" instead of "infinite".
