菜单按钮不会垂直移动

Question

我正在尝试为我的网站制作一个菜单打开按钮，但有一个小问题，当我尝试将其指定为垂直移动时，例如 margin-top: 100px 它不会移动。但是当我设置 margin-left 它会改变位置并水平移动！我不知道为什么会这样。我很想得到一些关于如何将菜单按钮进一步向下放置的建议。我感觉它与 span 属性有关，但我不知道。非常感谢任何帮助。

function openNav() {
  document.getElementById("myNav").style.width = "100%";
}
function closeNav() {
  document.getElementById("myNav").style.width = "0%";
}

Answer 1

I have a feeling it has something to do with the attribute being a span

没错，因为 span 默认情况下有 display: inline，如果您将其更改为 display: block 并应用一些 margin-top: 100px，您会看到它改变了位置。

.openNav{
  display: block;
  margin-top: 100px;
}
