Colleagues. I have the following code, but I can not centralize the form. I'm using the latest version of Bootstrap. Already tried to put align="center", but also did not work. See:
<div class="container">
<div class="row">
<div class="col-md-5" style="margin: 20px">
<form method="post">
<label>Faça seu acesso abaixo:</label>
<div class="input-group margin-bottom-sm">
<span class="input-group-addon"><i class="fa fa-envelope-o fa-fw"></i></span>
<input class="form-control" type="text" placeholder="Login">
</div>
<div class="input-group" style="margin-top: 10px">
<span class="input-group-addon"><i class="fa fa-key fa-fw"></i></span>
<input class="form-control" type="password" placeholder="Senha">
</div>
<div class="input-group" style="margin-top: 10px">
<button type="submit" class="btn btn-success">Acessar</button>
</div>
</form>
</div>
</div>
</div>
