Adjusting color of fixed offcanvas navbar to become transparent while scrolling

After creating a navbar with a transparent background, I am now using JavaScript to attempt changing the navigation bar to a solid color once someone scrolls down.
The issue is that when scrolling, the box-shadow at the bottom of the navbar changes instead of the color.

Expectation for the navigation bar to change colors on scroll:

.navbar-scrolled{
    background-color: #fff;
    color: #000;
    box-shadow: 0 3px 10px rgba(0, 0, 0, 0.15);
}

<script>
  const navEl = document.querySelector('.navbar');

  window.addEventListener('scroll', () => {
    if (window.scrollY >= 56) {
      navEl.classList.add('navbar-scrolled');
    }
    else if (window.scrollY < 56) {
      navEl.classList.remove('navbar-scrolled');
    }
  });
</script>

Answer №1

When I think about it, you seem to be neglecting the use of CSS codes within <style>.

Additionally, when using Bootstrap, make sure to set the background and color as fixed with the important declaration, just like this:

background-color: #fff important;

Good luck to you!
