移动主菜单后，我的悬停菜单出现问题。由于徽标，它所在的div比菜单div大。当我第一次编写菜单时，它位于div的顶部，悬停菜单显示正常。

我使用position绝对位置和相对位置将菜单div移动到父div的底部，将底部设置为0和右215px。之后，悬停菜单在主菜单上开始重叠。任何帮助表示赞赏。

Answer 1

为了使徽标适应headers身高：

#logo2 {

  display: block;
  width: auto;
  height: auto;
  max-height: 108px;

}

您已将菜单容器设置为绝对位置，我已将其设置为内联，因此它不会停留在徽标上方： - 请从position: absolute;移除#container，然后添加以下内容：line-height: 108px;，使菜单垂直居中。

为了使徽标略小于标题本身，同时将其置于中心位置，我在#logo中添加了以下内容：

max-height: 70px;
margin: 19px 10px 19px 10px;

#header {
  height: 108px;
  width: 1140px;
  background-color: #faa220;
  position: relative;
}

#Logo2 {
  float: left;
  display: block;
  width: auto;
  height: auto;
  max-height: 70px;
  margin: 19px 10px 19px 10px;
}

#header links {
  height: 50px;
  float: left;
  list-style: none;
  padding-top: 10px;
}

#container {
  overflow: hidden;
  background-color: #faa220;
  font-family: Arial, Helvetica, sans-serif;
  bottom: 0;
  right: 215px;
  line-height: 108px;
}

.container a {
  float: left;
  font-size: 18px;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  position: absolute;
}

.dropdown {
  float: left;
  overflow: hidden;
}

.dropdown .dropbtn {
  font-size: 18px;
  border: none;
  outline: none;
  color: white;
  padding: 14px 16px;
  background-color: inherit;
  cursor: pointer;
}

.container a:hover,
.dropdown:hover .dropbtn {
  background-color: #faa220;
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #faa220;
  min-width: 100px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
  position: absolute;
}

.dropdown-content a {
  float: none;
  color: white;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
  position: absolute;
  bottom: 0;
}

.dropdown-content a:hover {
  background-color: #faa220;
  position: absolute;
  bottom: 0;
}

.dropdown:hover .dropdown-content {
  position: absolute;
  display: block;
  bottom: 0;
}

PS。我不知道菜单交互是什么，但你可能会知道它。

Answer 2

解决了问题的一部分，并设法让下拉菜单实际显示每个项目在彼此之上。但是我没有找到如何把它的子菜单放在一边（如果这是你想要的？）并使菜单实际上放下 down 。希望这会让你走上正确的道路。

问题的部分来自html和html属性。

position

overflow
