Is there a way to turn a regular menu into a dropdown menu for small devices without modifying the HTML code? I have a responsive design, but I'm not sure how to add that 'hamburger menu' style.
Note: I am unable to make changes to the HTML
Here is the updated HTML code:
<div id="pai" class="row">
<div class="col-xs-12 col-xs-10">
<div class="menu">
<nav>
<div class="navbar-default" style="background-color: rgba(249,211,0,1.00);">
<div class="container-fluid">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<div class="collapse navbar-collapse" id="navbar-collapse">
<ul id="menu" class="nav navbar-nav">
<li class="LogoPosicao"> <img class="img-responsive" id="imagemBBlogo" src="BBomParaTodos.png" alt="Banco Do Brasil Logo"> </li>
<li><a class="Entenda" href="#" visibility="hidden">ENTENDA</a></li>
<li><a class="SemJuros" href="#" visibility="hidden">SEM JUROS</a></li>
<li><a class="Quebra">|</a></li>
<li id="telefoneC"><a class="tel" href="#"> <span class="glyphicon glyphicon-earphone"></span> (99) 9999-9999</a></li>
<li id="contatoLI"><a class="Contato" href="#Contato-Site" button type="button" data-toggle="button" aria-pressed="false" autocomplete="off">CONTATO</a></li>
</ul>
</div>
</div>
</div>
</nav>
</div>
</div>
