How to add a hamburger menu to bootstrap

Question

I need help with bootstrap nav. I want it to be switched using the hamburger icon on the mobile phone.

Here it is on codepen: http://codepen.io/sadman/pen/hfGwv

HTML code:

<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> 

My custom 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%; }

All you have to do is read the code at getbootstrap.com:

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>

To create an icon, you can use the glyphicon in Bootstrap:

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

And then control the icon size in css:

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