CSS图像翻转效果

Question

我有以下CSS尝试创建翻转效果:

#arrow {
    position:absolute;
    left:540px;
    top:150px;
    width:220px;
    height:120px;
}
#arrow a{
    display: block;
    width:220px;
    height:120px;
    text-decoration: none;
    background: url("images/arrow.jpg");
    background-position: 0 -120px;
    }
#arrow a:hover {
    background-position: 0 0;
    }

后来,div标签:

<div id="arrow">
    <a href="/arrow/arrow.htm"></a>
</div>

但是,当我的鼠标滚过图像时,它不会改变链接的背景位置.思考？

Answer 1

添加background-repeat: no-repeat到#arrow a.
