Question

最近我调整了bootstrap的菜单大小。现在问题是菜单项顶部的菜单项的文本位置。

我想将菜单项显示在菜单标题的中心。菜单项已在中心位置对齐。

的CSS：

.navbar .navbar-nav {
  display: inline-block;
  float: none;
}

.navbar .navbar-collapse {
  text-align: center;
}

.navbar {
  position: relative;
  min-height: 80px;
  margin-bottom: 20px;
  border: 1px solid transparent
}

从 .nav

中删除了最小高度

Answer 2

如果您使用浏览器的开发工具，则会看到您的链接（ul.nav）实际上是垂直居中对齐的，但列表在nav元素之前结束。那是因为你在导航栏上设置了min-height: 80px。我建议也添加填充，但不是@LKG的方式。相反，请删除最小高度规则，并仅将顶部和底部填充添加到.navbar。这样项目保持中心对齐。更新了fiddle并更新了代码：

.navbar {
  position: relative;
  margin-bottom: 20px;
  padding: 12px 0;
  border: 1px solid transparent
}
