Whenever I resize the window and try to click the navigation toggle button, it doesn't seem to work. The button is unresponsive. Can someone please help me figure out what the issue could be?
<nav class="navbar fixed-top navbar-expand-lg navbar-dark">
<div class="container-fluid">
<a class="navbar-brand" href="javascript:void(0)">
<h3 class="my-heading ">SKEWED</h3>
</a>
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="fa fa-bars mfa-white"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
