How Can I Dynamically Change My Navigation Bar\'s Color Based on Scroll Position?

Dynamic Navigation Bar Color with Scrolling

In your project, you mentioned facing an issue where the navigation bar acquires a background color after scrolling down. To resolve this, we can implement a solution that changes the navbar's color based on the scrolling position.

JavaScript Implementation:

To achieve this, add the following JavaScript code to the header of your HTML file:

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

This script continually monitors the scroll position. When the scrolltop value exceeds the height of the navbar, it adds a class called "scrolled" to the navbar, triggering the color change.

CSS Styling:

To update the navbar's color, create a stylesheet and include the following CSS:

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

The "#fff" value can be customized to your preferred color. When the "scrolled" class is applied to the navbar, its background color will transition to white smoothly.

Example:

To illustrate the functionality, you can refer to the following JsFiddle:

This example demonstrates how the navbar turns white after scrolling down. By implementing this solution, you can effectively change the color of your navigation bar dynamically based on the scroll position.
