Tabstrip tabs formatting

Hey,

I am trying to format the tabs of the tabstrip as a separate entity. I want to have a gap in between the tabs horizontally. Here is my html code. Can you help me with the classes/styles that I need to modify in order to achieve my design. Thanks

<div id="tabstrip">
      <ul>
      <li class="tab-apart">TEST 1</li>
      <li class="tab-apart">TEST 2</li>
      <li class="tab-apart">TEST 3</li>
    </ul>

     <div>Content 1</div>
      <div>Content 2</div>
      <div>Content 3</div>

</div>
