I can't get my Bootstrap 5 Navbar to appear transparent? - html

Question

My bootstrap Navbar is white and despite trying everything i can find on Stack i cant override the white to make it transparent.
I have tried setting the background to transparent
The image behind is set to VH100 so should be behind the nav
I have tried using Inspect and targeting every colour instruction i could find
I removed the bg class from the navbar thinking that would help
Here is my html
<nav class="navbar navbar-expand-sm navbar-light">
<div class="container-fluid">
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarTogglerDemo01">
<img src="/assets/images/MothersSpinesLogo.png" alt="Mothers Spines MS Logo">
<ul id="nav" class="navbar-nav ms-auto">
<li class="active nav-item">
<a class="nav-link"href="index.html">HOME</a>
</li>
<li class="nav-item">
<a class="nav-link" href="about.html">ABOUT</a>
</li>
<li class="nav-item">
<a class="nav-link" href="contact.html">CONTACT</a>
</li>
</ul>
</nav>
and my CSS;
/* Navigation */
.navbar-brand {
background-position: center;
background-repeat: no-repeat;
background-size: cover;
max-height: 60px;
max-width: 60px;
margin-left: 30px;
}
.navbar {
align-items: end;
background: none;
background-color: rgba(0, 0, 0, 0.0);
--bs-navbar-nav-link-padding-x: 3.5rem;
font-family: 'Montserrat';
font-size: 120%;
list-style-type: none;
letter-spacing: 1px;
--bs-navbar-toggler-border-color: rgba(0, 0, 0, 0.0);
}
.navbar a {
text-decoration: none;
color: #252525;
}
.nav-item {
padding-top: 25px;
}

Answer 1

.navbar { background-color: transparent; }
Add the following to the image: height: 100vh;, position: absolute; and top: 0;.
If you just set height: 100vh; to the image, the image will be full viewport height, but it will start AFTER the navbar. You want to place it below the navbar. You do this by setting position: absolute; and top: 0;.
In short, the problem is caused by the image.

Answer 2

It looks like there are issues with element placement. Code provided does work for overlaying the image.
img#bg {
position: absolute;
}
/* Navigation */
.navbar-brand {
background-position: center;
background-repeat: no-repeat;
background-size: cover;
max-height: 60px;
max-width: 60px;
margin-left: 30px;
}
.navbar {
align-items: end;
background: none;
background-color: transparent;
--bs-navbar-nav-link-padding-x: 3.5rem;
font-family: 'Montserrat';
font-size: 120%;
list-style-type: none;
letter-spacing: 1px;
--bs-navbar-toggler-border-color: rgba(0, 0, 0, 0.0);
}
.navbar a {
text-decoration: none;
color: #252525;
}
.nav-item {
padding-top: 25px;
}
