Bootstrap tabbed panel

Question

I'm trying to figure out how to get a "tabbed panel". I've got a panel and a tabbed menu working just fine, but there is a gap between the panel and the tabbed nav.

I'm still trying to figure out this Bootstrap framework, so any guidance would be most appreciated. I've enclosed a screenshot too of what it's appearing like screenshot of tabbed pane. I've taken out all the PHP code so it's easier to replicate.

Here's the code:

body {
  padding: 10px;
}

#exTab1 .tab-content {
  color: white;
  background-color: #428bca;
  padding: 5px 5px;
}

#exTab2 h3 {
  color: white;
  background-color: #428bca;
  padding: 5px 5px;
}


/* remove border radius for the tab */

#exTab1 .nav-pills > li > a {
  border-radius: 0;
}


/* change border radius for the tab , apply corners on top*/

#exTab3 .nav-pills > li > a {
  border-radius: 4px 4px 0 0;
}

#exTab3 .tab-content {
  color: white;
  background-color: #428bca;
  padding: 5px 5px;
}

    <li><a href="#services" data-toggle="tab"><strong>Services</strong></a>

  </ul>

  <div class="tab-content clearfix">

    <div class="tab-pane active" id="overview">
      <!-- Overview -->

Dropping the working code into our "portal" the styles etc are being pulled, screenshot:

Your code almost works, you just need to add jQuery and close assets tab <div> before starting the services <div>.

See working demo here https://jsfiddle.net/dLpm9hgy/2/

Or here:

body {
  padding: 10px;
}

#exTab1 .tab-content {
  color: white;
  background-color: #428bca;
  padding: 5px 15px;
}

#exTab2 h3 {
  color: white;
  background-color: #428bca;
  padding: 5px 15px;
}


/* remove border radius for the tab */

#exTab1 .nav-pills > li > a {
  border-radius: 0;
}


/* change border radius for the tab , apply corners on top*/

#exTab3 .nav-pills > li > a {
  border-radius: 4px 4px 0 0;
}

#exTab3 .tab-content {
  color: white;
  background-color: #428bca;
  padding: 5px 15px;
}
