Mais j'en ai besoin pour transparent * et fixé en haut

c'est mon css pour le rendre transparent mais il ne devient jamais transparent à la place il donne quelques nuances de couleurs.

c'est mon css

.transparent-navbar{
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";       /* IE 8 */
    filter: alpha(opacity=50);  /* IE 5-7 */
    -moz-opacity: 0.5;          /* Netscape */
    -khtml-opacity: 0.5;        /* Safari 1.x */
    opacity: 0.5;  
    box-shadow: 1px 5px black;

    -moz-box-shadow:    inset 0 0 10px #000000;
    -webkit-box-shadow: inset 0 0 10px #000000;
    box-shadow:         inset 0 0 10px #000000;
}

est-ce que quelqu'un peut m'aider s'il vous plait?

Bootstrap 4 est livré avec un bg-transparent classe. Appliquez cela à votre barre de navigation.

<div class="bg-primary">
    <div class="navbar navbar-dark bg-transparent">
         ...
    </div>
</div>
