Why is my Bootstrap Modal Appearing Behind the Background Overlay?

Bootstrap Modal Hidden Under Background

Issue:

Despite following the official Bootstrap documentation, a modal is appearing beneath the background overlay, preventing interaction.

Reproducing the Issue:

The code for reproducing the problem is similar to the example below:

<body>
    <p>Lorem ipsum dolor sit amet.</p>

    <div class="my-module">
        <div class="modal fade">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-body">Modal</div>
                </div>
            </div>
        </div>
    </div>
</body>

Root Cause:

The modal container (with the "fade" class) can become hidden when it has a non-default position, such as fixed or relative. This issue occurs when the modal container or its parent elements are positioned differently.

Resolution:

To fix the issue, ensure that the modal container and its parent elements have the default position. There are two approaches to achieve this:

  1. Move Modal Outside Positioned Elements:

    • Relocate the modal div outside any elements with special positioning (e.g., before the closing tag).

  2. Remove Position Properties:

    • Remove the "position" CSS properties from the modal container and its ancestors until the modal becomes visible. However, this may affect the page layout and functionality.
