这可能很难正确回答/解释，但是:
为学校元素建立小型网站。使用 Bootstrap 。当屏幕低于 780 像素时，导航栏会变成移动设计，单击按钮图标时会出现下拉菜单。
问题是菜单的目的是在打开时将其下方的内容推下，但它只是在某些页面上/在主页上的幻灯片下浏览我的内容，并且由于内容位于其上方而无法单击。
我试图包含所有相关代码，但它完全是一团糟。由于存在所有 HTML/CSS 以及 bootstrap 和 jquery 链接，因此很难在 jfiddle 中发布。
任何人都可以看到任何错误吗？
这是问题的屏幕截图:

最佳答案
在你的 CSS 文件中，你应该删除 height: 53px; 它就会起作用。
.bottomHeader {
border: 0px solid black;
background-color: transparent;
height: 53px;
}
更改为这个:
.bottomHeader {
border: 0px solid black;
background-color: transparent;
}
