html - 如何调整下拉菜单的高度 - CSS

Question

我正在尝试使用 css 调整下拉菜单的大小，但我的 css 有问题。我需要调整高度以使其看起来正常。请看截图。这是我的 CSS:

ul#nav {
  font-family: 'Lato', sans-serif;
  background: #ffffff;
  list-style: none;
  line-height: 40px;
}

ul#nav li {
  display: inline-block;
  position: relative;
  z-index: 8;
}

ul#nav li:hover {
  color: #000000;
  background: #ffffff;
}

ul#nav li a {
  font-size: 14px;
  font-weight: normal;
  color: #444444;
  height: 40px;
  display: block;
  padding: 0 15px;
  text-transform: uppercase;
  letter-spacing: 1px;
  line-height: 40px;
}

ul#nav li a:hover {
  background: #ffffff;
  color: #000000;
  text-decoration: none;
}

ul#nav li ul{
  display: none;
  float: left;
  position: absolute;
  top: 34;
  left: 0;
  z-index: 5;
  margin: 0;
  padding: 0;
  border: 1px solid #eeeeee;

  border-style: solid;
  border-width: 8px;  
  margin-left: -8px;
  bottom: 100%;
  width: 0;
  height: 0;
}


ul#nav li:hover ul{
  display: block;
  background: #ffffff;
}

ul#nav li ul li{
  background: #ffffff;
  color: #000000;
  min-width: 150px;
  width: 100%:
    white-space: nowrap;
  float: left;
  text-align: left;
}


ul#nav li ul li:hover {
  background: #ffffff;
}

ul#nav li ul li a:hover {
  color: #000000;
  background: #ffffff;
}

ul#nav li ul li a{
  text-align: left;
  padding-left: 10px;

将 height 属性添加到您的 ul#nav li ul 选择器。

像这样:

ul#nav li ul{
    display: none;
    float: left;
    position: absolute;
    height:200px;/*Note the change here. Edit the px to whatever you need */
    top: 34;
    left: 0;
    z-index: 5;
    margin: 0;
    padding: 0;
    border: 1px solid #eeeeee;
}

希望这对您有所帮助!
