所以这些天我放弃了 CSS3 动画,所以我现在正在玩它。但不幸的是,我在将 bg 图像定位到底部时遇到了问题。
这是我正在处理的代码:
  body {
  margin: 0;
  font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
  font-size: 14px;
  line-height: 20px;
  color: #333333;
  background: #A9D0F5 url("../image/bg-clouds.png") repeat-x fixed center bottom;
  animation: animatedBackground 40s linear infinite;
  -ms-animation: animatedBackground 40s linear infinite;
  -moz-animation: animatedBackground 40s linear infinite;
  -webkit-animation: animatedBackground 40s linear infinite;
  /*background-color: #008bcf;*/    
}
@-keyframes animatedBackground {
        from { background-position: 0 0; }
        to { background-position: 100% 0; }
    }
    @-webkit-keyframes animatedBackground {
        from { background-position: 0 0; }
        to { background-position: 100% 0; }
    }
    @-ms-keyframes animatedBackground {
        from { background-position: 0 0; }
        to { background-position: 100% 0; }
    }
    @-moz-keyframes animatedBackground {
        from { background-position: 0 0; }
        to { background-position: 100% 0; }
    }
这里似乎有什么问题?有任何想法吗?谢谢。
