CSS3 /CSS - spinning background image

Question

is it possible to spin a background-image in css?

i can spin an element using:

@-webkit-keyframes spinX
{  
0%   {-webkit-transform: rotateX(0deg); -webkit-transform-origin: 0% 50% 0;}  
100% {-webkit-transform: rotateX(360deg); -webkit-transform-origin: 0% 50% 0;}  
}

@-webkit-keyframes spinY
{  
0%   {-webkit-transform: rotateY(0deg); -webkit-transform-origin: 0% 0% 5;}  
100% {-webkit-transform: rotateY(360deg); -webkit-transform-origin: 0% 0% 5;}  
}  

but what about if i want to spin an element's background-image?

can't find nothing, i can use gif but i would like to make it in css if possible !

any idea? thanks

i forgot to say if is possible to make the animation cross-browsers supported :P

Answer 1

You can do that setting the background on a pseudo element, for instance an after

.main {
    width: 200px;
    height: 300px;
    position: relative;
    border: solid 1px gray;
}

.main:after {
    width: 100%;
    height: 100%;
    position: absolute;
    background: url("http://placekitten.com/800/1200");
    background-size: cover;
    content: '';
    -webkit-animation: spinX 3s infinite;
    animation: spinX 3s infinite;
}

@-webkit-keyframes spinX
{  
0%   {-webkit-transform: rotateX(0deg); -webkit-transform-origin: 0% 50% 0;}  
100% {-webkit-transform: rotateX(360deg); -webkit-transform-origin: 0% 50% 0;}  
}
@keyframes spinX
{  
0%   {transform: rotateX(0deg); transform-origin: 0% 50% 0;}  
100% {transform: rotateX(360deg); transform-origin: 0% 50% 0;}  
}

<div class="main"></div>

Answer 2

You could put the background on a pseudo element, like ::before and animate that.

Example, and another one :)

If you have content above the image, add z-index: -1 to the pseudo element.
