            <nav class="navbar navbar-expand-lg navbar-light bg-company-red">

                <button class="navbar-toggler" type="button" >
                    <span class="navbar-toggler-icon">
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                    </span>
