How Can I Change My Navbar\'s Background Color on Scroll?

Dynamic Nav-Bar Color Change on Scrolling

Enhance your website's navigation experience by transforming the nav-bar color as you scroll down the page. In this question, the user sought guidance to remove the background color of the nav-bar initially and then apply a color when scrolling past a specific div.

Solution:

The solution involves a combination of JavaScript and CSS. First, add the following JavaScript code to your HTML document's head section:

$(function () {
  $(document).scroll(function () {
    var $nav = $(".navbar-fixed-top");
    $nav.toggleClass('scrolled', $(this).scrollTop() > $nav.height());
  });
});

This JavaScript code monitors the window's scroll position and toggles the "scrolled" class on the nav-bar when the scroll exceeds the nav-bar's height.

Next, add the following CSS code to your stylesheet:

.navbar-fixed-top.scrolled {
  background-color: #fff !important;
  transition: background-color 200ms linear;
}

This CSS ensures that when the "scrolled" class is applied to the nav-bar, its background color changes to white (#fff) with a smooth transition over 200 milliseconds.

By implementing this solution, you can create a dynamic navigation bar that enhances the user experience by providing a visual cue as they scroll through the page's content.
