vue.js bootstrap-5 css sticky HTML/CSS

I'm deploying to production and I'm trying to implement a sticky header in my Vue 3 application using Bootstrap 5, but it doesn't seem to stick when scrolling down the page... I set up my header with `position: sticky;` and a `top: 0;` style, but instead of sticking when I scroll past it, it just scrolls off the screen like a regular element. Here is the relevant HTML and CSS: ```html <template> <header class="sticky-top"> <nav class="navbar navbar-expand-lg navbar-light bg-light"> <a class="navbar-brand" href="#">My Site</a> <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarNav"> <ul class="navbar-nav"> <li class="nav-item"> <a class="nav-link active" aria-current="page" href="#">Home</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Features</a> </li> </ul> </div> </nav> </header> </template> ``` ```css .sticky-top { position: sticky; top: 0; z-index: 1020; // Default Bootstrap z-index for sticky elements } ``` The question seems to be related to the parent container of the header. I verified that the parent elements do not have any conflicting overflow properties that might interfere with sticky positioning. I also checked the viewport height, and the header is inside a scrollable container, which is set with `overflow-y: auto;`. However, I still see that the header doesn't stick when I scroll down. I tried moving the sticky class to a different wrapper and adjusting the z-index, but nothing seems to work. I also checked the browser compatibility, and it should work on the latest versions of Chrome and Firefox. Can someone guide to understand what I might be missing or if there are specific conditions under which `position: sticky;` will not function properly in this setup? My team is using Html/Css for this web app. Could someone point me to the right documentation? This is for a REST API running on Debian. Any feedback is welcome! Am I missing something obvious?
