当导航栏中的某些元素较大时,其他元素将不是中心和彼此对齐。这里可以看到一个例子:http://jsfiddle.net/3c236jft/3/

<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
  <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
    <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="#">Brand</a>
</div>

<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
  <ul class="nav navbar-nav">
    <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>
      <ul class="dropdown-menu" role="menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li class="divider"></li>
        <li><a href="#">Separated link</a></li>
        <li class="divider"></li>
        <li><a href="#">One more separated link</a></li>
      </ul>
    </li>
  </ul>
  <form class="navbar-form navbar-left" role="search">
    <div class="form-group">
      <input type="text" class="form-control" placeholder="Search">
    </div>
    <button type="submit" class="btn btn-default">Submit</button>
  </form>
  <ul class="nav navbar-nav navbar-right">
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false"><img src="http://thevectorlab.net/metrolab/img/avatar-mini.png" class="img-circle"> Dropdown <span class="caret"></span></a>
      <ul class="dropdown-menu" role="menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li class="divider"></li>
        <li><a href="#">Separated link</a></li>
      </ul>
    </li>
  </ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>

如何让每个元素成为导航栏的垂直中心,而不会给下拉菜单等其他元素带来麻烦?

您可能需要针对您添加的额外非标准项目调整该项目。

在这里,我已经更新了您的小提琴,使用下拉菜单等,并考虑了图像:

在此处编辑代码:(我在nopadding

中添加了class="..."
<li class="dropdown">
          <a href="#" class="dropdown-toggle nopadding" data-toggle="dropdown" role="button" aria-expanded="false"><img src="http://thevectorlab.net/metrolab/img/avatar-mini.png" class="img-circle"> Dropdown <span class="caret"></span></a>../li>

我补充说:

a.dropdown-toggle.nopadding {padding-top:8px;padding-bottom:0px;}
