Twitter-Bootstrap-2 logo image on top of navbar

问题

Can someone suggest how I can place a logo image on the top of the navbar? My markup:

  <body>
    <a href="index.html"> <img src="images/57x57x300.jpg"></a>
     <div class="navbar navbar-fixed-top">
       <div class="navbar-inner">
         <div class="container">

It is not working as the 57x57x300.jpg is shown below the navbar.

You have to also add the "navbar-brand" class to your image a container, also you have to include it inside the .navbar-inner container, like so:

 <div class="navbar navbar-fixed-top">
   <div class="navbar-inner">
     <div class="container">
        <a class="navbar-brand" href="index.html"> <img src="images/57x57x300.jpg"></a>
     </div>
   </div>
 </div>

Overwrite the brand class, either in the bootstrap.css or a new CSS file, as below -

.brand
{
  background: url(images/logo.png) no-repeat left center;
  height: 20px;
  width: 100px;
}

and your html should look like -

<div class="container-fluid">
  <a class="brand" href="index.html"></a>
</div>

You should remove navbar-fixed-top class otherwise navbar stays fixed on top of page where you want logo.

If you want to place logo inside navbar:

Navbar height (set in @navbarHeight LESS variable) is 40px by default. Your logo has to fit inside or you have to make navbar higher first.

Then use brand class:

<div class="navbar navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container">
      <a href="/" class="brand"><img alt="" src="/logo.gif" /></a>
    </div>
  </div>
</div>

If your logo is higher than 20px, you have to fix stylesheets as well.

If you do that in LESS:

.navbar .brand {
  @elementHeight: 32px;
  padding: ((@navbarHeight - @elementHeight) / 2 - 2) 20px ((@navbarHeight - @elementHeight) / 2 + 2);
}

@elementHeight should be set to your image height.

Padding calculation is taken from Twitter Bootstrap LESS - https://github.com/twitter/bootstrap/blob/v2.0.4/less/navbar.less#L51-52

Alternatively you can calculate padding values yourself and use pure CSS.

This works for Twitter Bootstrap versions 2.0.x, should work in 2.1 as well, but padding calculation was changed a bit: https://github.com/twitter/bootstrap/blob/v2.1.0/less/navbar.less#L50

i use this code for navbar on bootstrap 3.2.0, the image should be at most 50px high, or else it will bleed the standard bs navbar.

Notice that i purposely do not use the class='navbar-brand' as that introduces padding on the image

<div class="navbar navbar-default navbar-fixed-top" role="navigation">
    <div class="container">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
        <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="" href="/"><img src='img/anyWidthx50.png'/></a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse navbar-ex1-collapse">
       <ul class="nav navbar-nav">
        <li class="active"><a href="#">Active Link</a></li>
        <li><a href="#">More Links</a></li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div>
</div>

If you do not increase the height of navbar..

 .navbar .brand {
 position: fixed;    
 overflow: visible;
 padding-left: 0;    
 padding-top: 0;
 }
