Question

我使用以下代码创建一个简单的右侧垂直菜单

#cssmenu {
  padding: 0;
  margin: 0;
  border: 0;
}
#cssmenu ul,
#cssmenu li {
  list-style: none;
  margin: 0;
  padding: 0;
}
#cssmenu ul {
  position: relative;
  z-index: 597;
  float: right;
}
#cssmenu ul li {
  float: right;
  min-height: 1px;
  line-height: 1.5em;
  vertical-align: middle;
  text-align:right;  
}
#cssmenu ul li.hover,
#cssmenu ul li:hover {
  position: relative;
  z-index: 599;
  cursor: default;
}
#cssmenu ul ul {
  visibility: hidden;
  position: absolute;
  top: 100%;
  right: 0;
  z-index: 598;
  width: 100%;
}
#cssmenu ul ul li {
  float: none;
}
#cssmenu ul ul,
#cssmenu ul ul ul {
  top: -1px;
  right: 99%;
}
#cssmenu ul li:hover > ul {
  visibility: visible;
}
#cssmenu ul li {
  float: none;
}
#cssmenu a {
  display: block;

然而，在将此菜单添加到所有页面后，我发现页面的所有内容都在菜单之后。

Screenshot

如何让内容从页面顶部开始？

Answer 1

您可以使用float：

#cssmenu {
  padding: 0;
  margin: 0;
  border: 0;
  float: right;
}

使用菜单内嵌显示内容
