I have been developing a website and running into an issue with the header. It works fine on desktop and is responsive, but on mobile devices, the Bootstrap functionality seems to be missing. I've included my code below, could someone please help me identify what's causing this problem?
<div class="continer-fluid">
<nav class="navbar navbar-inverse bg-inverse navbar-fixed-top">
<div class="navbar navbar-expand-lg ">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="container">
<a href="/" class="navbar-brand">
<img src="{% static "app/content/collectore-luxury-logo11.png" %}" width="30" height="30" class="d-inline-block align-top" alt="">
Website
</a>
<div class="collapse navbar-collapse " id="#navbarSupportedContent">
<ul class="nav navbar-nav mr-auto mt-2 mt-lg-0">
<li class="nav-item"><a href="{% url 'home' %}">Home</a></li>
<li class="nav-item"><a href="{% url 'about' %}">About</a></li>
<li class="nav-item"><a href="Medium Blog">Blog</a></li>
<li class="nav-item"><a href="{% url 'New Thing' %}">New Thing</a></li>
</ul>
