Question

我将导航栏min-height从40更改为55以使用徽标。

.navbar{
    position:relative;
    min-height:55px
}

我想知道如何更改navbar按钮的高度：

<div class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
        <span class="sr-only">Navigation ein-/ausblenden</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="http://holdirbootstrap.de/examples/navbar-fixed-top/#"> <img src="images/logoverysmall.png">Company</a>       
    </div
    <div class="navbar-collapse collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="dev.htm">Home</a></li>
        <li><a href="http://holdirbootstrap.de/examples/navbar-fixed-top/#ueber">Über uns</a></li>
        <li><a href="http://holdirbootstrap.de/examples/navbar-fixed-top/#kontakt">Product</a></li>

        <li class="dropdown">
        <a href="#" data-toggle="dropdown" class="dropdown-toggle">0<b class="caret"></b></a>
        <ul class="dropdown-menu">
            <li><a href="#">1</a></li>
            <li><a href="#">2</a></li>
            <li><a href="#">3</a></li>
        </ul>
      </li>
      <li><a href="/kontakt">Kontakt</a></li>
      </ul>
    </div><!--/.nav-collapse -->
  </div>
  </div>
 </div>

Answer 1

通常，在bootstrap中，他们已经设置了导航栏高度。因此，如果要修改高度，请使用以下代码

  .navbar
   {
      position:relative;
      height:55px !important;
   }

在为特定导航栏编写样式的地方，为所有元素添加“！important”，因为在运行时它只需要运行时css。所以使用'！important'这个词。
