Responsive TopNavbar with Dropdown not working

[Pranay0302]

The code is given below:

 <nav class="navbar navbar-expand-lg fixed-top bg-dark navbar-custom" style="box-shadow: 0px 0px 12px 7px;">
        <div class="container"><a class="navbar-brand" href="index.html" style="font-family: Catamaran, sans-serif;">fooooooool</a><button data-toggle="collapse" class="navbar-toggler" data-target="#navbarResponsive"><span class="navbar-toggler-icon"></span></button>
            <div class="collapse navbar-collapse" id="navbarResponsive" style="background-color: rgb(52 58 64);">
                <ul class="nav navbar-nav ml-auto">
                    <li class="nav-item" role="presentation"><a class="nav-link" href="about.html">ABout</a></li>
                    <li class="nav-item" role="presentation"><a class="nav-link" href="contact.html">ConTACT</a></li>
                </ul>
            </div>
        </div>
    </nav>
