添加桌面布局时，移动菜单中的下边距(或空格)奇怪

Question

我正在为一个网站设计一个移动菜单(使用代码笔(。菜单的桌面布局已经编写完毕。

移动布局已编写完毕，并且按预期工作正常。但是，添加桌面布局后，移动布局的菜单底部会出现一个奇怪的空间。桌面布局保持不变。

布局可以在以下位置找到： https://codepen.io/pcassima/pen/ZgWYOd这仅包括菜单的 HTML 和样式。

我已经尝试注释掉桌面布局中的填充和边距，但这不会删除空间。

我希望移动菜单中菜单栏底部没有空间。

function hamburgerNav() {
  // Get the navigation list from the page
  let nav_list = document.getElementById("nav-list");
  // Get the hamburger from the page (to change the shape)
  let hamburger = document.getElementById("hamburger");
  // Add or remove the active class from the navigation list
  if (nav_list.classList.contains("active")) {
    nav_list.classList.remove("active");
  } else {
    nav_list.classList.add("active");
  }
  // Add or remove the active class from the hamburger
  if (hamburger.classList.contains("active")) {
    hamburger.classList.remove("active");
  } else {
    hamburger.classList.add("active");
  }
}

Answer 1

如果我

理解正确，那么如果您删除 .top-navbar 类上的显示内联块，您应该直观地看到空格消失/删除。

仅供参考：仅当移动菜单处于活动状态时，才应将其删除。在桌面版本上，这仍然是必要的。
