Bootstrap 5 Modal not centering properly on smaller screens
I'm migrating some code and Does anyone know how to I'm using Bootstrap 5.1.3 for a web project and I've run into an issue where my modal isn't centering correctly on smaller screens... The modal appears to be offset to the top-left instead of being centered both vertically and horizontally. I’ve checked the Bootstrap documentation and implemented the modal as described there. Here’s the modal HTML code I'm using: ```html <div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal Title</h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> Modal body content goes here. </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div> ``` I also have the Bootstrap CSS and JS included in my project as follows: ```html <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/5.1.3/css/bootstrap.min.css"> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.9.3/dist/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/5.1.3/js/bootstrap.min.js"></script> ``` When I open the modal on screens smaller than 576px, the modal doesn't appear in the center and there’s a noticeable gap from the top. I have also tried adding custom CSS with `margin: auto` for the modal-dialog, but it did not help: ```css .modal-dialog { margin: auto; } ``` I’m not seeing any JavaScript errors in the console, but I’ve tried using `data-bs-backdrop="static"` in case the backdrop might be affecting the positioning. Is there something I'm missing in my implementation, or a known issue with Bootstrap modals in this version that might cause this behavior? For reference, this is a production web app. Any examples would be super helpful. I'm coming from a different tech stack and learning Html. This issue appeared after updating to Html 3.10.
