CSS3动画位置

Question

考虑使用船舶在蓝色div上方移动的CSS3动画.由于某种原因,船没有移动.HTML如下:

<div id="wrapper">
  <div id="sea">
    <img src="ship.png" alt="ship" width="128" height="128"/>
  </div>
</div>

为了制作CSS3动画,我使用以下内容:

#wrapper { position:relative;top:50px;width:700px;height:320px;
          margin:0 auto;background:white;border-radius:10px;}
#sea { position:relative;background:#2875DE;width:700px;height:170px;
       border-radius:10px;top:190px; }
#sea img { 
  position:relative;left:480px;top:-20px;
  animation:myship 10s;
  -moz-animation:myship 10s; /* Firefox */
  -webkit-animation:myship 10s; /* Safari and Chrome */
  @keyframes myship {
    from {left: 480px;} 
    to{left:20px;} 
   }
   @-moz-keyframes myship {
     from {left: 480px;} 
     to {left:20px;} 
   }
   @-webkit-keyframes myship {
     from {left: 480px;} 
     to{left:20px;} 
   }
}

船舶图像没有移动.任何帮助是极大的赞赏.

你必须在css选择器之外声明你的关键帧,以及为绝对定位的元素设置动画.

你修改过的css看起来像这样:

#wrapper{
    position:relative;
    top:50px;
    width:700px;
    height:320px;
    margin:0 auto;
    background:white;
    border-radius:10px;
}
#sea{
    position:relative;
    background:#2875DE;
    width:700px;
    height:170px;
    border-radius:10px;
    top:190px;
}
#sea img{
    position:absolute;
    left:480px;
    top:-20px;
    animation:myship 10s;
    -moz-animation:myship 10s; /* Firefox */
    -webkit-animation:myship 10s; /* Safari and Chrome */               
}

@keyframes myship{
    from {left: 480px;} 
    to{left:20px;} 
}
@-moz-keyframes myship{
    from {left: 480px;} 
    to{left:20px;} 
}
@-webkit-keyframes myship{
    from {left: 480px;} 
    to{left:20px;} 
}?
