Why won't my Twitter Bootstrap navigation bar apply the styles?

I am currently working on a Rails app (4.0) and have incorporated Bootstrap 3 into my project. Both bootstrap.css and bootstrap-theme.css are stored in the stylesheets directory, while bootstrap.js is located in the javascripts directory. Most of the Bootstrap styles are functioning correctly, such as .btn-group and .btn-primary. I am attempting to create a navbar using the following HAML code:

.navbar.navbar-fixed-top
    .navbar-inner
        .container
            %a.brand{:href => '#'} Site Name
            %ul.nav
                %li.active
                    %a{:href => '#'} Home
                %li
                    %a{:href => '#'} Link 1
                %li
                    %a{:href => '#'} Link 2

However, the navbar appears vertically stacked instead of horizontally, and the 'brand' element is missing its styles. You can view how it looks here: http://jsfiddle.net/JLt9u/

I am unsure why this is happening. Is it possible that I am using outdated class names? I have searched through various resources on Stack Overflow but haven't found a solution yet. Any assistance would be greatly appreciated!

Answer №1

Your current markup is outdated (2.x) and does not align with the new styles. To update your markup, refer to the Bootstrap documentation:

<nav class="navbar navbar-default navbar-fixed-top">
  <ul class="nav navbar-nav">
    <li class="active"><a href="#">Home</a></li>
    <li><a href="#">Link 1</a></li>
    <li><a href="#">Link 2</a></li>
  </ul>
</nav>

If you are transitioning from version 2.x to 3.0, there is a dedicated section in the documentation for guidance: Migration Documentation.
