Question

我有一个问题，我的侧面导航（出现在较小的屏幕上）并不会覆盖身体的内容（文字，图片等）。我的z-index设置为500为我的侧导航，0为我的身体内容，这似乎没有解决我认为的问题。

这是一个jfiddle：https://jsfiddle.net/timothykeyseraude/0w5wynLs/

html {
height: 100%
}

谢谢！

Answer 1

将z-index：1添加到＆＃34; navbar-header-foundation＆＃34;课程，你的问题将得到解决。

Answer 2

你的问题是你在p标签上使用position: absolute ...所以请关闭它，这将解决您的问题，如果您想将文字居中，可以使用text-align: center

Answer 3

将侧面导航放在标题之外，heasder将获取其父标题的z-index。见下文。

＆＃13;

// script.js


// ======= NavBar ======= //

function openNav() {
  document.getElementById("side-navigation").style.width = "100%";
}

function closeNav() {
  document.getElementById("side-navigation").style.width = "0";
}
