溢出:隐藏似乎不起作用

标签: html css html5 css3 overflow

我正在创建一个响应式菜单,并且仅使用html和css。

但是当我尝试向网站添加内容时,它会在菜单中启动div。我已经尝试使用溢出:隐藏在整个菜单上的div上但由于某种原因这不起作用。

我创建了另一个菜单,并使用了溢出:隐藏在菜单周围的div上,虽然有效,但很遗憾无法使用它,因为它没有下拉菜单。

我希望我能为您提供足够的信息来帮助我其他明智的问题! 感谢。

你想要什么与overflow无关。

因为在1201px以上的设备上,您的菜单中包含position:absolute,因此您要将其从正常的文档流中删除。如果您不希望它与页面内容重叠,则需要在内容上设置顶部填充并将菜单放在提供的空间中:

@media (min-width: 1201px){
  body {
    padding-top: 51px;
  }
  #menu {
    top: 0;
  }
}

作为旁注,您的CSS 过于笼统 。对于初学者,您不希望网站中的所有无序列表都有position:absolute
