Question

Looking to troubleshoot a white background issue while attempting to create a transparent navbar

I am trying to create a full-page landing with a transparent navbar using bootstrap4. My goal is to have a sticky navbar that remains at the top as the user scrolls down the page.

When I apply the class 'fixed-top', the navbar stays at the top but doesn't stick as I scroll. However, when I use 'sticky-top', the background of the navbar turns white.

<nav class="navbar navbar-expand-md navbar-dark bg-dark sticky-top">
    <div class="container-fluid">
         <a href="#" class="navbar-brand">Brand</a>
         <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarToggler-1" aria-controls="navbarToggler-1" aria-expanded="false" aria-label="Toggle navigation">
          <span class="navbar-toggler-icon"></span>
         </button>

.bg-dark{
    background-color: transparent !important;
}

To remove the class "bg-dark" when it becomes sticky, you can achieve this through JavaScript or by using a combination of CSS and body classes. For CSS-only solution, you can add the following code: ( body .bg-dark{background:none;} header .bg-dark{background:none;} ) You can also use the !important keyword if needed.

$(window).scroll(function() {    
    var scroll = $(window).scrollTop();

    if (scroll >= 300) {
        $(".navbar").addClass("sticky_nav");
        $(".navbar").removeClass("bg-dark");
    } else {
        $(".navbar").removeClass("sticky_nav");
        $(".navbar").addClass("bg-dark");
    }
});

.navbar.sticky_nav{
    position: fixed;
    top: 0;
    width: 100%;
    left: 0;
    z-index: 99;
}

         </button>
         </div>
  </nav>
