所以我设置我的标题以使用滚动淡入淡出，但是显示为悬停。它适用于所有图像，但投资组合部分中的猫图片。我调整了z索引，并尝试了一切。标题不会出现在h4上或问题文件下面的任何内容下面是portfolio.html。标题显示在其他图片上方。这让我发疯了。 https://github.com/alil0rphan/Basic-Portfolio

尝试在position: absolute;选择器中添加body.scrolled #main-menu。它看起来像这样：
body.scrolled #main-menu {
opacity: 0.2;
transition: opacity .2s;
z-index: 98;
position: absolute;
}
