Question

我有以下一页设置，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：之前的div，并相应地设置z-index，使得带有文本的div与前面的div重叠：背景图像。一切正常，直到我插入jquery插件fullPage.js。

此时，似乎z-index无法正常工作：在div与文本重叠div之前。

我怀疑可能与jquery.fullPage.css存在冲突，如下所示。 任何想法？

Answer 1

通过添加位置：相对于z-index：2来固定节div，以及设置z-index：-1到div :: before。

.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;
}

z-index不仅适用于fullPage.js
