Bootstrap - Navigation bars

bootstrap

How can we create navigation bar that include buttons and form?

<nav class="navbar navbar-default">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Brand</a>
    </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 class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
        <li><a href="#">Link</a></li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">Separated link</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
      </ul>
      <form class="navbar-form navbar-left" role="search">
        <div class="form-group">
          <input type="text" class="form-control" placeholder="Search">
        </div>
        <button type="submit" class="btn btn-default">Submit</button>
      </form>
      <ul class="nav navbar-nav navbar-right">
        <li><a href="#">Link</a></li>
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">Separated link</a></li>
          </ul>
        </li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

Place form content within .navbar-form for proper vertical alignment and collapsed behavior in narrow viewports. Use the alignment options to decide where it resides within the navbar content. The .navbar-form shares much of its code with .form-inline. Some form controls, like input groups, may require fixed widths to be show up properly within a navbar.

<form class="navbar-form navbar-left" role="search">
  <div class="form-group">
    <input type="text" class="form-control" placeholder="Search">
  </div>
  <button type="submit" class="btn btn-default">Submit</button>
</form>

Why should we add .navbar-btn class to <button> elements not residing in a <form>?

Add the .navbar-btn class to <button> elements not residing in a <form> to vertically center them in the navbar.

<button type="button" class="btn btn-default navbar-btn">Sign in</button>

Like the standard button classes, .navbar-btn can be used on <a> and <input> elements. However, neither .navbar-btn nor the standard button classes should be used on <a> elements within .navbar-nav.

Why should we wrap strings of text in an element with .navbar-text?

Wrap strings of text in an element with .navbar-text, usually on a <p> tag for proper leading and color.

<p class="navbar-text">Signed in as Mark Otto</p>

Why should we add .navbar-link class?

For folks using standard links that are not within the regular navbar navigation component, use the .navbar-link class to add the proper colors for the default and inverse navbar options.

<p class="navbar-text navbar-right">Signed in as <a href="#" class="navbar-link">Mark Otto</a></p>

How can we align navigation components?

Use the .navbar-left or .navbar-right utility classes. Both classes will add a CSS float in the specified direction. Navbars currently have a limitation with multiple .navbar-right classes. To properly space content, we use negative margin on the last .navbar-right element. When there are multiple elements using that class, these margins don't work as intended.

How can we fix the navigation to the top?

Add .navbar-fixed-top and include a .container or .container-fluid to center and pad navbar content.

<nav class="navbar navbar-default navbar-fixed-top">
  <div class="container">
    ...
  </div>
</nav>

Body padding required: The fixed navbar will overlay your other content, unless you add padding to the top of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.

body { padding-top: 70px; }

Make sure to include this after the core Bootstrap CSS.

How can we fix our navigation bar to the bottom?

Add .navbar-fixed-bottom and include a .container or .container-fluid to center and pad navbar content.

<nav class="navbar navbar-default navbar-fixed-bottom">
  <div class="container">
    ...
  </div>
</nav>

Body padding required: The fixed navbar will overlay your other content, unless you add padding to the bottom of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.

body { padding-bottom: 70px; }

Make sure to include this after the core Bootstrap CSS.

What is an inverted navigation bar?

NOT SURE, but you add navbar-inverse:

<nav class="navbar navbar-inverse">
  ...
</nav>
