and here html 

<div class="container">     <div id="center"></div>     <div id="small"></div> </div>

you need use -webkit prefix proprietary property ensure animation runs in webkit browsers

you need use prefix webkit browsers

demo

.container {     margin: 0 auto;     position: relative; }  #center {     width: 300px;     height: 300px;     margin: 225px auto 0;     border: 5px solid #ddd;     border-radius: 100%;     background: #aaa; }  @keyframes rot {     {         transform:         rotate(0deg)                            translate(-150px)                            rotate(0deg);         -webkit-transform: rotate(0deg)                            translate(-150px)                            rotate(0deg);     }     {         transform:         rotate(360deg)                            translate(-150px)                             rotate(-360deg);         -webkit-transform: rotate(360deg)                            translate(-150px)                             rotate(-360deg);     } }  @-webkit-keyframes rot {     {           transform:        rotate(0deg)                             translate(-150px)                             rotate(0deg);          -webkit-transform: rotate(0deg)                             translate(-150px)                             rotate(0deg);     }     {         transform:          rotate(360deg)                             translate(-150px)                              rotate(-360deg);         -webkit-transform:  rotate(360deg)                             translate(-150px)                              rotate(-360deg);     } }  #small {     position: absolute;     width: 75px;     height: 75px;     border: 5px solid #ddd;     border-radius: 100%;     background: #aaa;     animation: rot 3s infinite linear;     -webkit-animation: rot 3s linear infinite;     transform-origin: 50% 200px;     -webkit-transform-origin: 50% 200px; }

side note: should use proprietary properties of each browser i.e -moz, -webkit, -o , -ms older versions of browser don't fail animate
