如何在bootstrap中添加汉堡菜单

我需要一些帮助的引导程序导航。 我希望通过手机上的汉堡图标来切换。

这里是codepen: http ://codepen.io/sadman/pen/hfGwv

HTML代码:

<nav class="navbar navbar-inverse navbar-static-top" role="navigation"> <div class="container"> <ul class="nav navbar-nav"> <li><a href="index.php">Home</a></li> <li><a href="about.php">About</a></li> <li><a href="#portfolio">Portfolio</a></li> <li><a href="#">Blog</a></li> <li><a href="contact.php">Contact</a></li> </ul> </div> </nav> 

我的自定义CSS:

 .navbar, .navbar-inverse { border-radius: 0; border: none; margin-bottom: 0; min-height: 80px; } .nav li { display: inline; color: white; } .navbar-inverse .navbar-nav > li > a { color: #ffffff; font-family: Lato; font-size: 1.7em; font-weight: 300; padding: 30px 25px 33px 25px; } .navbar-inverse .navbar-nav li a:hover { background-color: #444444; transition: 0.7s all linear; height: 100%; } 

你所要做的就是阅读getbootstrap.com上的代码:

Codepen

 <nav class="navbar navbar-inverse navbar-static-top" role="navigation"> <div class="container"> <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> </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><a href="index.php">Home</a></li> <li><a href="about.php">About</a></li> <li><a href="#portfolio">Portfolio</a></li> <li><a href="#">Blog</a></li> <li><a href="contact.php">Contact</a></li> </ul> </div> </div> </nav> 

要创build图标,可以在Bootstrap中使用glyphicon:

 <a href="#" class="btn btn-info btn-sm"> <span class="glyphicon glyphicon-menu-hamburger"></span> </a> 

然后在css中控制图标的大小:

 .glyphicon-menu-hamburger { font-size: npx; }
