Here's a solution to prevent the "jump" effect when hiding elements in a navbar

Currently, I am facing an issue with my h5 elements within the navbar when scrolling. I am using Bootstrap 4 and jQuery for this project.

The problem arises in my navbar where there are four sets containing an icon, followed by an "h5" and then a "p" element stacked on top of each other. As the page is scrolled down, I only want to display the "h5" element.

To achieve this, I have used JavaScript hide and show methods. However, after hiding the elements and setting the display to "none", the "h5" element jumps slightly to occupy the center of the navbar.

I am looking for a solution to eliminate this minor jump at the end.

I have attempted transitions with opacity, visibility, height = 0, and others. While they partially work, I still need to manually readjust the position of the h5 element. I am wondering if there is a simpler solution to this issue.

<!--NAVBAR-->
// Navbar code here
</nav>
<!--NAVBAR-->

<div class="container">Placeholder Lorem Ipsum content here.</div>

// Scripts go here

CSS Code:

// CSS styling goes here

body {
    background-color: rgb(65, 61, 61);
}

nav {
    background-color: dimgray;
}

#mainNavbar {
    padding-bottom: 0;
    transition: all 0.7s ease;
}

.navbar-brand {
    color: white;
}

// More CSS styles...

In essence, my goal is to smoothly fade out the icon and the "p" elements when the user scrolls down.

It seems like you're on the right track! The definition of "smoothly" can vary depending on your project's specific needs.

To achieve a simpler and more straightforward solution, consider removing the transition time from the hide and show functions. Here is an example:

if ($(document).scrollTop() > $("#mainNavbar").height()) {
    $("figure i").hide();
    $("figure p").hide();
    $("nav").css("height", "50px");
 }
else {
    $("figure i").show();
    $("figure p").show();
    $("nav").css("height", "128px");
};

In addition, consider adjusting the transition time of the #mainNavbar to be 0.4s instead of 0.8s.

This change will improve the visual effect by reducing any delays or jumps in element positioning. It ultimately depends on how smoothly you want your project to appear, but these adjustments align with standard practices for websites.

If you prefer a slower disappearance for the icons and text, consider setting all elements to have a position: fixed. This way, they won't interfere with each other's space and can smoothly transition without impacting layout.
