How to put a background to the drop down hamburger menu

[ethanforbes89]

I have a horizontal navigation bar. However, when the screen gets to small, it closes up to one of the hamburger icons that can be clicked, and then it opens up vertically. The problem I am having is that it’s just the words. No solid background or anything with it. And it is also behind some of the elements that it should be covering up. I can’t seem to figure out where in my code I need to adjust the css to manage this. Here is my html for my nav bar:

<nav class="navbar navbar-inverse navsize">
    <div class="container-fluid">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" ><img id="logo" src="/Images/SC2_MyLink_Logo.png" alt="SC2 Logo"/></a>
        </div>
        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul id="navposition" class="nav navbar-nav">
                <li class="individualbtnposition col-lg-2"><a href="/">Home</a></li>
                <li class="dropdown individualbtnposition">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Our Company<span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li><a href="/OurCompany">Our History</a></li>
                        <li><a href="/OurCompany/Facilities">Facilities</a></li>
                    </ul>
                </li>
                <li class="dropdown individualbtnposition">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Employee Services<span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li class="dropdown dropdown-submenu">
                            <a href="#" class="dropdown-toggle" data-toggle="dropdown">Forms</a>
                            <ul class="dropdown-menu">

                    </ul>
                </li>
                <li class="dropdown individualbtnposition">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown">Support Services<span class="caret"></span></a>
                    <ul class="dropdown-menu">
                        <li><a href="#">IT Support</a></li>

                </li>
            </ul>
        </div>
    </div>
    <div class="logout col-lg-1">
        <a href="/Home/Logout">Sign Out</a>
    </div>
</nav>
