CSS animation not working on mobile

Question

I have this code and it works on my PC browser, and Galaxy Note 4 phone. It animates an SVG element. But when I test on a Moto X phone (Chrome browser), it does not work. Does anyone know why? I tried to put in all the prefix tags.

 @keyframes example { 0% { -webkit-transform: rotate(0deg); -moz-transform: rotate(0deg); -ms-transform: rotate(0deg); -o-transform: rotate(0deg); transform: rotate(0deg); } 25% { -webkit-transform: rotate(45deg); -moz-transform: rotate(45deg); -ms-transform: rotate(45deg); -o-transform: rotate(45deg); transform: rotate(45deg); } 50% { -webkit-transform: rotate(0deg); -moz-transform: rotate(0deg); -ms-transform: rotate(0deg); -o-transform: rotate(0deg); transform: rotate(0deg); } 75% { -webkit-transform: rotate(-45deg); -moz-transform: rotate(-45deg); -ms-transform: rotate(-45deg); -o-transform: rotate(-45deg); transform: rotate(-45deg); } 100% { -webkit-transform: rotate(0deg); -moz-transform: rotate(0deg); -ms-transform: rotate(0deg); -o-transform: rotate(0deg); transform: rotate(0deg); } } #left_leg_group { animation: example 1s linear infinite; /* and here*/ animation-timing-function: ease-in-out; -webkit-transform: translate3d(0, 0, 0); -moz-transform: translate3d(0, 0, 0); -ms-transform: translate3d(0, 0, 0); -o-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); -webkit-transform-origin: 50% -10%; -moz-transform-origin: 50% -10%; -ms-transform-origin: 50% -10%; -o-transform-origin: 50% -10%; transform-origin: 50% -10%; } #right_leg_group { animation: example 1s linear infinite; /* and here*/ animation-timing-function: ease-in-out; animation-delay: 0.1s; -webkit-transform: translate3d(0, 0, 0); -moz-transform: translate3d(0, 0, 0); -ms-transform: translate3d(0, 0, 0); -o-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); -webkit-transform-origin: 50% -10%; -moz-transform-origin: 50% -10%; -ms-transform-origin: 50% -10%; -o-transform-origin: 50% -10%; transform-origin: 50% -10%; }

Answer 1

@keyframe also needs prefixing, as does animation . Also, you are setting animation-timing-function to ease-in-out after explicitly setting it in animation ( animation: example 1s linear infinite; ).

Try this:

 @-webkit-keyframes example { 0% { -webkit-transform: rotate(0deg); transform: rotate(0deg); } 25% { -webkit-transform: rotate(45deg); transform: rotate(45deg); } 50% { -webkit-transform: rotate(0deg); transform: rotate(0deg); } 75% { -webkit-transform: rotate(-45deg); transform: rotate(-45deg); } 100% { -webkit-transform: rotate(0deg); transform: rotate(0deg); } } @keyframes example { 0% { -webkit-transform: rotate(0deg); -moz-transform: rotate(0deg); -ms-transform: rotate(0deg); -o-transform: rotate(0deg); transform: rotate(0deg); } 25% { -webkit-transform: rotate(45deg); -moz-transform: rotate(45deg); -ms-transform: rotate(45deg); -o-transform: rotate(45deg); transform: rotate(45deg); } 50% { -webkit-transform: rotate(0deg); -moz-transform: rotate(0deg); -ms-transform: rotate(0deg); -o-transform: rotate(0deg); transform: rotate(0deg); } 75% { -webkit-transform: rotate(-45deg); -moz-transform: rotate(-45deg); -ms-transform: rotate(-45deg); -o-transform: rotate(-45deg); transform: rotate(-45deg); } 100% { -webkit-transform: rotate(0deg); -moz-transform: rotate(0deg); -ms-transform: rotate(0deg); -o-transform: rotate(0deg); transform: rotate(0deg); } } #left_leg_group { -webkit-animation: example 1s ease-in-out infinite; animation: example 1s ease-in-out infinite; /* and here*/ -webkit-transform: translate3d(0, 0, 0); -moz-transform: translate3d(0, 0, 0); -ms-transform: translate3d(0, 0, 0); -o-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); -webkit-transform-origin: 50% -10%; -moz-transform-origin: 50% -10%; -ms-transform-origin: 50% -10%; -o-transform-origin: 50% -10%; transform-origin: 50% -10%; } #right_leg_group { -webkit-animation: example 1s ease-in-out 0.1s infinite; animation: example 1s ease-in-out 0.1s infinite; /* and here*/ -webkit-transform: translate3d(0, 0, 0); -moz-transform: translate3d(0, 0, 0); -ms-transform: translate3d(0, 0, 0); -o-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); -webkit-transform-origin: 50% -10%; -moz-transform-origin: 50% -10%; -ms-transform-origin: 50% -10%; -o-transform-origin: 50% -10%; transform-origin: 50% -10%; }
