Question

我试图让菜单项消失，然后转移到第二行，并且当我调整浏览器大小时菜单项消失后立即弹出3栏菜单。 http://jsfiddle.net/qwwru7eh/

到目前为止，我尝试使用display none和display：block with inline css style tags来设置媒体查询样式：
我将Bootstrap的问题与以下代码隔离开来，但是我无法通过样式化获得所需的效果：

@media（min-width：872px）{。navbar-toggle {       display：none; }}

@media（max-width：871px）{。navbar-nav .open .dropdown-menu {       位置：静态;       float：none;显示：无;       宽度：自动;       margin-top：0;       背景颜色：透明;       边界：0;       -webkit-box-shadow：none;               box-shadow：none; } .navbar-nav .open .dropdown-menu＆gt; li> a，.navbar-nav .open .dropdown-menu .dropdown-header {       填充：5px 15px 5px 25px; } .navbar-nav .open .dropdown-menu＆gt; li>一个 {       行高：20px; } .navbar-nav .open .dropdown-menu＆gt; li> a：悬停，.navbar-nav .open .dropdown-menu＆gt; li> a：焦点{       background-image：none; }}

HTML：

<nav class="container-fluid navbar navbar-inverse navbar-static-top">

        <div class="container-fluid">

            <!--Logo!-->
            <div class="navbar-header">
                <a href="#" class="navbar-brand">THE LOGO</a>

             <!--Toggle Button 3 Lines -->                      
               <button type="button" class="navbar-toggle customtogglebtn" data-toggle="collapse" data-target="#mainNavBar">
               <span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span>

                        </ul>
                    </li>

                </ul>

                <!--Right-Align Menu Items!-->
                <ul class="nav navbar-nav navbar-right">
                    <li><a href="#">Logout</a></li>
                </ul> 
            </div>              
        </div>
    </nav>




         <!--Page Content -->






<div class="container-fluid belowstatic" style="height:1000px; background:#333; bottom:0;">

静态导航栏

CSS：

        body { padding-top: 51px;}

        .navbar-toggle { outline:none; border:none; margin-right:-5px; background:none;}

        .navbar-static-top {
  top: 0;
  position: fixed;
  left: 0;
  right: 0;
  margin: 0 auto;
  z-index: 1; 
}

如果有人知道设置引导菜单项元素的最佳方式，请告诉我如何操作，并告诉我关于样式引导元素的最佳实践。谢谢！

Answer 1

您有几个选项，第一个选项是减少使用此媒体查询可以执行的菜单项周围的填充：

@media (min-width: 768px) {
  .navbar-nav>li>a {
      padding:15px 10px;
  }
}

JSFiddle example

如果您不想更改填充，另一个选项是缩小字体大小：

body { 
  padding-top: 51px;
  font-size:13px;
}

您只需要链接jquery。您的菜单将正常工作。我正在向您发送代码以及链接。如果有任何更改，请告诉我。
