HTML CSS - nav-tabs, data-toggle="tab" - html

Question

I have a problem editing an HTML page. I need to change the content on the second tab on the nav-tabs, the one with the name Anexos. I tried to create a new href, but this didn't work. What do I need to do?
</div>
<ul class="nav nav-tabs">
<li class="active"><a data-toggle="tab" href="#adm_carteiras">Formulário</a></li>
<li><a data-toggle="tab" href="#utilizacao">Anexos</a></li>
<li><a data-toggle="tab" href="#utilizacao">Versões</a></li>
</ul>
<div class="tab-content">
<div id="adm_carteiras" class="tab-pane fade in active">
<div class="row">
<div class="col-md-12">
<div class="filtrar_cliente box" style="padding-bottom:25px;">
<div class="box_conteudo">
<div class="box_conteudo">
<h1 class="title_box">Solicitação de Viagem</h1>
<div class="adm_carteiras box">
<div class="box_conteudo">
<h4>Nome do Solicitante:</h4><br>
</div>
</div>

Answer 1

this is the correct bootstrap nav-tabs structure
<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<ul class="nav nav-tabs" role="tablist">
<li role="presentation" class="active">Home</li>
<li role="presentation">Profile</li>
<li role="presentation">Messages</li>
<li role="presentation">Settings</li>
</ul>
<div class="tab-content">
<div role="tabpanel" class="tab-pane active" id="home">...</div>
<div role="tabpanel" class="tab-pane" id="profile">...</div>
<div role="tabpanel" class="tab-pane" id="messages">...</div>
<div role="tabpanel" class="tab-pane" id="settings">...</div>
</div>
