How to Dynamically Change Navbar Color on Scroll?
Dynamic Navbar Color Change While Scrolling
Achieving a navbar with no background color initially and progressively changing its color after scrolling requires a combination of JavaScript and CSS modifications.
JavaScript:
$(function () { $(document).scroll(function () { var $nav = $(".navbar-fixed-top"); $nav.toggleClass('scrolled', $(this).scrollTop() > $nav.height()); }); });
This code checks for the vertical scroll position of the document. If it exceeds the height of the navbar, it toggles a class "scrolled" to the navbar element.
CSS:
.navbar-fixed-top.scrolled { background-color: #fff !important; transition: background-color 200ms linear; }
This CSS code defines the appearance of the navbar with the "scrolled" class. It applies a white background color and a smooth transition effect while changing the color.
Implementation:
By adding the provided JavaScript code to the head of your HTML document and the CSS code to your style sheet, you can easily implement this dynamic navbar color change. When the user scrolls down the page, the navbar will gradually transition to the desired background color.
