所以我是新手使用CSS动画，并认为我会玩它来学习它。我可以在Chrome中显示所有内容并且工作正常但是如果FF和Safari，我很难正确显示它。 （在FF中，前景动画不起作用，在Safari中只有旋转才有效。）
我的HTML是基本的：
<html>
<head>
<title>Happy Birthday!</title>
<link rel="stylesheet" href="styles.css" media="all" />
</head>
<body>
<div class="wrapper">
<div class="carebear"></div>
</div>
<div class="foreground"></div>
<div class="midground"></div>
<div class="background"></div>
</body>
</html>
我的CSS：
html {
background: url('bg.jpg') 0 100% repeat-x;
width:100%;
height: 100%;
}
.carebear {
background: url('care3.png')0 0 no-repeat;
width: 295px;
height: 274px;
