CSS3 Animation not working in Mozilla - css

Question

I've read other answers for the same question in stackoverflow, but I couldn't solve it with them.
My code doesn't work in mozilla, can anyone help me?
Besides that, Can anyone tell me the correct way to use #keyframes. I mean, is it correct to use #-webkit-keyframes, #-moz-keyframes and #keyframes, or with only one it should be fine?
Thanks
header .resaltar {
color: #F3D85E;
font-weight: bold;
}
header .resaltar:hover {
-webkit-animation: shake 0.8s linear infinite;
-moz-animation: shake 0.8s linear infinite;
-ms-animation: shake 0.8s linear infinite;
animation: shake 0.8s linear infinite;
-webkit-transform-origin: 50% 50%;
-moz-transform-origin: 50% 50%;
-ms-transform-origin: 50% 50%;
transform-origin: 50% 50%;
}

Answer 1

the problem you are having is animation to a span element.
i noticed that if u apply this animation to the parent element (the header) it works fine.
I think your problem is that the display of the span is inline
Once i changed the display to inline-block, it worked fine with me
header .resaltar {
color: #F3D85E;
font-weight: bold;
display: inline-block;
}
