Holo spinner example with images doesn't work while pure CSS does

问题

Related to this question: Android Holo loading spinner in CSS I have noticed that the accepted answer's first example, the one with images, doesn't work on chrome (i just see a static grey ring) while it works on Firefox and IE 11.

Even though the purpose of the question was to make a spinner without images and both are very nice I find the first one slightly better looking (on firefox, that is) and i'd like to use it but I don't know why it doesn't work on chrome and I want to know if there's a fix, both for future references (so i know what to avoid and/or how to fix it) and to know if I must stick to the one without images

My Chrome version is 42.0.2311.90 (32-bit)

Since i assumed both spinners were correct i didn't realize it was missing the webkit-keyframes property. Today i watched once again the css and noticed by chance that the css spinner had it while the image-based spinner didn't. Adding this to the image based spinner css worked

@-webkit-keyframes rotate-outer {
    0% {
        -webkit-transform: rotate(0deg);
    }
    100% {
        -webkit-transform: rotate(1080deg);
    }
}

@-webkit-keyframes rotate-inner {
    0% {
        -webkit-transform: rotate(720deg);
    }
    100% {
        -webkit-transform: rotate(0deg);
    }
}
