由于容器DIV的背景属性,我遇到了CSS转换无法正常工作的问题。这是我在网上冲浪的一段代码,但找不到我所在的页面,所以我不能回去问他们。这意味着什么,是一个普通的按钮,但当盘旋时,两个段落滑出(一个在顶部,一个在底部)。它本身就可以正常工作,但是当我将它放入容器DIV中,并在容器上放置背景颜色时,它就不再有效了。我Firebugged它发现,当我禁用BG属性时,它可以工作。疯狂的是,过渡是在边缘,而与BG没有任何关系。忍受我,这是我的第一个问题,我将尝试正确插入代码......

请尝试以下操作: Demo

.download-button a {
    z-index: 100;
    position:relative;
}

.download-button p {  
    z-index: 0;
}

<p>代码边距有negative z-index值,这就是为什么它落后于#container bg,现在我将z-index值更改为积极并为<a>提供更多z-index值的位置,以显示在前面
