我正在尝试同时运行两个动画。一切对我来说看起来都很完美，但它的行为真的很古怪，我不知道为什么。我想把整个事情都保存在 CSS 中。

正如评论中所发布的，这是工作页面的当前版本：fallowproduction.com/cowabduction/csspractice1.html

它目前只能在 chrome 中 100% 运行，或者我想是 Safari。

CSS 表在这里：fallowproduction.com/cowabduction/practice1StyleSheet.css

如果你注意到，最左边的那头牛就是我正在研究的那头。当不明飞行物在他上方时，他应该向上移动（据我所知，这一切都是正确的）。然而，相反，他只是慢慢地消失了

这是代码的摘录：

    .ufo {
left: 0px;
top: 0px;
z-index: 25;
left: 0px;
top: 0px;
width= 225px; 
height= 142px;
position: absolute;

animation: move_ufo 180s ease 0 1;
-moz-animation: move_ufo 180s ease 0 1; /* Firefox 4 */ 
-webkit-animation: move_ufo 180s ease 0 1; /* Safari and Chrome */
-o-animation: move_ufo 180s ease 0 1; /* Opera */

}

Try this:

@-webkit-keyframes move_cow1 {
    0% { opacity: 1; left: 80px; top: 450px; } 
    19.93% { opacity: 1; left: 80px; top: 450px; } /* UFO is at cow1 */
    22.73% { opacity: 1; left: 80px; top: 61px; }  /* cow1 is being lifted */
    22.74% { opacity: 0; } /* cow1 disappears */

    51.75% { left: 4px; top: 61px; }
    54.55% { left: 4px; top: 61px; }   /* Move to cow7*/
    100% { left: 80px; top: 450px; }

}
