srcmini我正在尝试使用HTML和CSS为WordPress构建自定义主题。我遇到的问题是Hero Image似乎总是在固定的顶部导航栏上方-我尝试搜索相似的帖子, 但使用此特定代码集找不到任何内容。向下滚动时, 你会看到固定的导航消失, 然后在英雄图像后重新出现；我最初的倾向是与职位有关(相对/绝对), 但这种变化无济于事。非常感谢任何支持-谢谢！

你是否尝试过将z-index：999添加到.topnav。
#2
你只需要添加一个z-index：
.topnav {
overflow: hidden;
background-color: #e9e9e9;
position: fixed;
top: 0;
width: 100%;
z-index:1000;//add z-index
}
