How to add hamburger menu in bootstrap

Question

I need some help with bootstrap nav. I want it to be toggled via a hamburger icon on mobile.

Here it is on codepen: http://codepen.io/sadman/pen/hfGwv (link invalid)

.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%;  }
