CSS3 - 在精灵图像的“背景位置”之间淡入淡出

CBu*_*atu 5 css image fade sprite background-position

我只想使用 CSS在精灵图像的“背景位置”之间淡入淡出。我找到了很多教程,但没有找到像这样简单的东西:

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>CSS3 - Fade between 'background-position' of a sprite image</title>
<style type="text/css">
div{
    width:  120px;
    height: 60px;

    background-image:       url('sprite.jpg');
    background-repeat:      no-repeat;
    background-position:    0   0;

}
div:hover{
    background-position:    0   -60px;
}
</style>
</head>
<body>
<div></div>
</html>
