I'm trying to get the dropdown aspect of bootstrap's navbar to work, and I haven't been able to get the menu to actually drop down. It's so faint I've colored it black to get it to show on the page, but when I click on it, it won't provide any options. JSFiddle here.
Im using the code below for the navbar itself.
<nav class="navbar navbar-expand-md topHeader">
<a class="navbar-brand nameHeader">
<h1 class="navbarHeader">David Mitchell Barnett</h1>
</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar" aria-controls="collapsibleNavbar" aria-expanded="false" aria-label="Toggle navigation" style="background-color: black" >
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="collapsibleNavbar">
<ul class="navbar-nav ml-auto">
<li class="nav-item">
<a class="nav-link" href="index.html">
<h3>About</h3>
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="portfolio.html">
<h3>Portfolio</h3>
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="contact.html">
<h3>Contact</h3>
</a>
</li>
</ul>
</div>
</nav>
