Bootstrap - 'tabbable' class

[smus]

I need the tabs to be on the left(horizontally). Tried to use the class "tabbable tabs-left" (class="tabbable tabs-left")
but it doesn't work. They continue to be on the bottom (by default), as in the official
example(http://getbootstrap.com/2.3.2/components.html#navbar):

<div class="tabbable tabs-left"> 
  <ul class="nav nav-tabs">
    <li class="active"><a href="#tab1" data-toggle="tab">Section 1</a></li>
    <li><a href="#tab2" data-toggle="tab">Section 2</a></li>
  </ul>
  <div class="tab-content">
    <div class="tab-pane active" id="tab1">
      <p>I'm in Section 1.</p>
    </div>
    <div class="tab-pane" id="tab2">
      <p>Howdy, I'm in Section 2.</p>
    </div>
  </div>
</div>

Maybe anyone know what is wrong?

Thank you very much!

 

Just one more question: is it possible to create the same features in W3.css by adding appropriate css code? Or it is also supports only horizontal positioning?

W3.css is simple light weight poor mans alternative, it does not have half the features of bootstrap, you will have to copy the same css classes and styling used in bootstrap for tabs and use in w3.css or custom css file.

Yes, you are right. Thanks a lot!
