png24格式的图片在用jQuery添加显示隐藏动画时发现，图片的半透明区域出现黑边？

在网上搜了搜主要有以下几种办法：

1、把图片保存成PNG-8格式。

2、把背景色一起切入并保存为JPG格式。

以上两种方法我试了试，好像效果并不好png8格式仍就会有黑边。

解决方法：

1、不要直接改变图片的透明度，而是给图片套个容器，去修改这个容器的透明度

2、给这个容器加个颜色相近的背景颜色（非常重要，解决bug的关键就在这一步，）

一般情况下，到此bug就解决了，如果还是有问题，请看下面：

3、给容器加个zoom: 1

（个人觉得这种办法只不过是一个障眼法，没有从根本上解决问题，看来目前只能这样了，期待有更好的方法）
