Question

出于某种原因，我的Navbar似乎有0个顶部填充，并略微偏向右侧。

HTML几乎是一个直接复制＆amp;从例子中粘贴，我不能为我的生活弄清楚为什么它不起作用。

Answer 1

你有两个<div class="container"></div>，它们都有一个偏移量。删除其中一个，看看是否能解决您的问题。

Answer 2

对于某些属性，

Bootstrap似乎需要自定义.css文件，在这种情况下，导航栏顶部处理由＆＃34; navbar.css＆＃34;

处理

body {
  padding-top: 20px;
  padding-bottom: 20px;
}

.navbar {
  margin-bottom: 20px;
}

创建此文件并将其链接到标题似乎可以解决问题。

Bootstrap navbar未对齐
