    #animbg{ width:120px; height:120px; position: absolute; top: 50%; left: 50%; margin-top: -60px; margin-left: -60px; overflow: hidden; }
    #anim{-webkit-animation: auto-circle 0.5s step-end infinite;;}

    @-webkit-keyframes auto-circle{
        0%{-webkit-transform:translate3d(0,0,0);}
        20%{-webkit-transform:translate3d(-120px,0,0);}
        40%{-webkit-transform:translate3d(-240px,0,0);}
        60%{-webkit-transform:translate3d(-360px,0,0);}
        80%{-webkit-transform:translate3d(-480px,0,0);}
        100%{-webkit-transform:translate3d(-600px,0,0);}
    }
  </style>
</head>
<body>
    <div id="animbg">
        <img id="anim" src="images/anim.png"></div>
    </div>
</body>
</html>

更高效的方法：

    #anim{-webkit-animation: auto-circle 0.5s steps(6) infinite;;}
 
    @-webkit-keyframes auto-circle{
        0%{-webkit-transform:translate3d(0,0,0);}
        100%{-webkit-transform:translate3d(-720px,0,0);}
    }

更好的自适应效果和方法：

.ideal-people img {
    height: 100%;
    width: auto;
    -webkit-animation: idealLoop 4s steps(15) infinite;
}
@-webkit-keyframes idealLoop {
    0% {
        -webkit-transform: translateX(0);
    }
    100% {
        -webkit-transform: translateX(-100%);
    }
}
