I am seeking assistance in creating a responsive Navbar that transitions from transparent to solid when the screen size changes, such as on a smartphone. I want the Navbar to remain fixed at the top of the page and not move down as I scroll. I tried adding the "bg-dark" class but this removes the transparency. Here is my current code:
#main {
position: relative;
background: url('https://images.template.net/wp-content/uploads/2016/10/15125202/Beautiful-Travel-Photography.jpg?width=600');
min-height: 100vh;
background-size: cover;
background-position: center;
padding: 220px 0 200px;
}
#header {
position: absolute;
z-index: 10;
width: 100%;
}
.navbar-dark .navbar-brand {
color: #ffffff;
}
.nav-item {
font-weight: bold;
text-transform: uppercase;
padding-left: 10px;
}
.navbar-dark .navbar-nav .nav-item .nav-link:hover {
background: #bbbbbb;
color: #ffffff;
}
.navbar-nav > li {
margin-top: 7px;
padding-left: 10px;
padding-right: 10px;
}
.navbar-brand {
color: #fff;
margin-top: 5px;
font-size: 25px;
text-transform: uppercase;
font-weight: bold;
opacity: 0.9;
letter-spacing: 2px;
}
.navbar-brand:hover {
color: grey;
}
.fa {
margin-top: 5px;
}
.fa:hover {
opacity: 0.7;
}
.fa-facebook {
color: white;
