Creating two classes is essential for achieving a transparent navbar that changes upon scrolling. By utilizing JavaScript, you can monitor the scroll event and toggle between the classes seamlessly.
Below is a simple example to demonstrate this functionality.
// Utilizes jQuery library.
function updateNavbar() {
var scroll = document.documentElement.scrollTop || document.body.scrollTop;
if (scroll > 0) {
$('.navbar').addClass("navbar-light");
} else {
$('.navbar').removeClass("navbar-light");
}
}
$(document).ready(function() {
$(document).scroll(function() {
updateNavbar();
});
updateNavbar();
});
html {
background-color: gray;
}
body {
margin: 0;
padding-bottom: 1000px;
}
.navbar {
height: 100px;
line-height: 100px;
padding-left: 35px;
padding-right: 30px;
display: flex;
position: fixed;
top: 0;
right: 0;
left: 0;
color: white;
transition: 0.15s ease all;
transition: 0.08s ease height line-height;
}
.navbar-light {
background-color: white;
height: 70px;
line-height: 70px;
color: black;
}
.navbar-links a {
margin-left: 5px;
margin-right: 5px;
color: white;
}
.navbar-light a {
color: black;
}
.fill-space {
flex: 1 1 auto;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="navbar">
<span>Navbar</span>
<span class="fill-space"></span>
<div class="navbar-links">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</div>
If you are involved in website development, I highly suggest familiarizing yourself with Bootstrap v4. It's an invaluable tool that simplifies the design process significantly.
