我有以下一页设置，其中包含一个容器和 3 个 div。我为视差效果的 3 个 div 中的每一个设置了一个 :before div，并相应地设置了 z-index，以便带有文本的 div 与带有背景图像的 :before div 重叠。一切正常，直到我插入 jquery 插件 fullPage.js。
此时，z-index 似乎无法正常工作，因为 :before div 将 div 与文本重叠。
我怀疑可能与下面找到的 jquery.fullPage.css 有冲突。 有什么想法吗？

通过将 position: relative 和 z-index: 2 添加到 divs 部分，并将 z-index: -1 设置为 div::before 来修复。
.bio {
background-color: #252839;
font-size: 1em;
color: #f2b632;
text-align: center;
display: flex;
justify-content: center;
align-items: center;
position: relative;
z-index: 2;
padding: 0 30px;
}
.bio:before {
content: ' ';
display: block;
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: -1;
opacity: 0.1;
background-image: url(../images/logo1.svg);
background-repeat: no-repeat;
background-position: center;
background-attachment: fixed;
}
关于jquery - z-index 不适用于 fullPage.js，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48633841/
