Adjusting transparency to a specific setting

I am working on creating a navigation bar that gradually fades in as the user scrolls through it on larger screens. I want to maintain some level of transparency for the navigation bar and have full opacity for the font within it.

  1. Is there a way to achieve this effect without the entire navigation bar becoming completely opaque during the scroll action?

$(window).resize(function() {

    if ($(window).width() < 480) {
        $('.navbar').removeClass("navbar-fixed-top"); 
        $('.navbar').css('opacity', 1)
    } else {
        $('.navbar').css('opacity', 0)
    }
});

$(document).on('scroll', function(e) {
    if ($(window).width() > 480) 
        $('.navbar').css('opacity', ($(document).scrollTop() / 900));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Answer №1

To achieve a slightly transparent background, you can use the CSS property background-color: rgba(); This will only affect the opacity of the background itself. If you apply opacity to the entire wrapper, it will also affect any child elements within it.
