Bootstrap 导航栏文本/按钮位于页面下方

Question

我在标题中使用以下代码来提供固定的引导导航栏：

<header class="site-header">

<a class="site-title" href="{{ site.baseurl }}/">{{ site.title }}</a>

    <!-- START NAVBAR/HEADER -->
    <nav class="navbar navbar-fixed-top navbar-inverse" role="navigation">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <a class="navbar-brand" href="http://xxxx.github.io">Your Name</a>
            </div>

            <!-- Collect the nav links, forms, and other content for toggling -->
            <div class="collapse navbar-collapse navbar-ex1-collapse">
                <ul class="nav navbar-nav">
                    <li><a href="http://xxxx.github.io/pages/About.html">About</a>
                    </li>
                    <li><a href="http://xxxx.github.io/pages/Blog.html">Blog</a>
                    </li>
                    <li><a href="http://xxxx.github.io/pages/Contact.html">Contact</a>
                    </li>
                </ul>
                <ul class="nav navbar-nav navbar-right">
                    <li><a href="https://twitter.com/VitamnD"><i class="fa fa-twitter fa-2x"></i></a>
                    </li>
                    <li><a href="https://instagram.com/vitamnd/"><i class="fa fa-instagram fa-2x"></i></a>
                    </li>
                    <li><a href="https://github.com/xxxx"><i class="fa fa-github fa-2x"></i></a>
                    </li>
                    <li><a href="https://linkedin.com/in/yourname/"><i class="fa fa-linkedin fa-2x"></i></a>
                    </li>
                </ul>
            </div>
            <!-- /.navbar-collapse -->
        </div>
        <!-- /.container -->
    </nav>
    <!-- END NAVBAR -->

这段代码在我的基本网站的早期迭代中运行良好： http://xxxx.github.io

但是我现在将此代码添加到 header.html 文件中以便迁移到 Jekyll。

在这种情况下，它会生成一个宽大的导航栏，文本和按钮位于页面的中间，如所附屏幕截图所示：

如果将导航栏高度添加到 CSS 中，导航栏高度会发生变化，但按钮会保持在同一位置：

Answer 1

这可能是什么搞砸了：

@media(min-width:768px) {
   header .container {
      padding: 200px 0 100px;
   }
}

对我来说毫无意义:)
