Bootstrap 移动导航对齐

Question

我正在开发一个网站，需要一些有关导航栏的帮助。正如您在代码笔中看到的那样，我需要有关 li 项目、徽标和切换按钮的垂直对齐方面的帮助。我还需要有关早期断点的帮助，因此 ul 不会与图像重叠。我什么都试过了，但我卡住了。

    <nav class="navbar navbar-default">
     <div class="container-fluid">
       <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span> 
      </button>
      <a href="#"><div class="logo"></div></a>
    </div>
    <div class="collapse navbar-collapse navbar-right" id="myNavbar">
      <ul class="nav navbar-nav">
        <li><a href="#">About</a></li>
        <li><a href="#">Stats</a></li>
        <li><a href="#">Drivers</a></li> 
        <li><a href="#">Contact</a></li>
        <li id="btn"><a href="#">Pledge Now</a></li> 
      </ul>
    </div>
  </div>
</nav>

Answer 1

您可以为navbar 添加行高，然后调整徽标的内边距以垂直对齐所有内容。

就早期断点而言，您只需要获取移动设备的 CSS navbar 并将其应用到在示例 CSS 中用注释注明的新断点处覆盖。

*我还为您的navbar（示例中为custom-navbar）添加了一个自定义类，以避免直接更改 Bootstrap CSS（尤其是关于您正在使用的container 类）和如果将来需要进行更改，这将使维护变得更加简单等。这不是必需的，但我认为总体上是一种很好的做法。

**这也可能是出于其他原因，但我使用了navbar-fixed-top 而不是将navbar 包装在一个固定的标头类中。同样，不是必需的，但可能有用。

查看示例代码段。
