Navigation Bars
A navigation bar is a navigation header that is placed at the top of the page:
With Bootstrap, a navigation bar can extend or collapse, depending on the screen size.
A standard navigation bar is created with
<nav class="navbar navbar-default">.
The following example shows how to add a navigation bar to the top of the page:
<nav class="navbar navbar-default"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand" href="#">WebSiteName</a> </div> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Page 1</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div></nav>
Inverted Navigation Bar
If you don't like the style of the default navigation bar, Bootstrap provides an alternative, black navbar:
Just change the
.navbar-default class into .navbar-inverse:<nav class="navbar navbar-inverse"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand" href="#">WebSiteName</a> </div> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Page 1</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div></nav>
Fixed Navigation Bar
The navigation bar can also be fixed at the top or at the bottom of the page.
A fixed navigation bar stays visible in a fixed position (top or bottom) independent of the page scroll.
The .navbar-fixed-top class makes the navigation bar fixed at the top:<nav class="navbar navbar-inverse navbar-fixed-top"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand" href="#">WebSiteName</a> </div> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Page 1</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div></nav>
Navigation Bar With Dropdown
Navigation bars can also hold dropdown menus.
The following example adds a dropdown menu for the "Page 1" button:
<nav class="navbar navbar-inverse"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand" href="#">WebSiteName</a> </div> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li class="dropdown"> <a class="dropdown-toggle" data-toggle="dropdown" href="#">Page 1 <span class="caret"></span></a> <ul class="dropdown-menu"> <li><a href="#">Page 1-1</a></li> <li><a href="#">Page 1-2</a></li> <li><a href="#">Page 1-3</a></li> </ul> </li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div></nav>
