I recently created a landing page using Bootstrap, but I'm having an issue with the navbar not being fixed. Here is the code for the navbar:
<nav class="navbar fixed-top navbar-inverse bg-primary navbar-toggleable-md navbar-light bg-faded">
<div class="container">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
</ul>
</div>
<a class="navbar-brand pull-sm-right mr-10" href="#">Aquastars Swimming School</a>
</div>
</nav>
