Modal Not Overlayed Properly: Troubleshooting and Solutions

When implementing modals using Bootstrap, you may encounter a situation where the modal appears underneath the background and becomes inaccessible. This issue can arise when the modal container or its parent elements possess a fixed or relative CSS position.

Causes:

The problematic behavior stems from the conflict between Bootstrap's positioning mechanism for modals and the fixed or relative position of the modal container.

Solutions:

To resolve this issue, ensure that the modal container and all of its parent elements are positioned the default way:

Option 1: Move the modal div outside any elements with special positioning, such as those with fixed or relative CSS properties. A suitable location would be just before the closing tag.
Option 2: Remove position: CSS properties from the modal and its ancestors until the problem disappears. However, this may alter the appearance and functionality of the page.

Example Solution:

<code class="html"><body>
  <p>Lorem ipsum dolor sit amet.</p>    

  <div class="my-module">
    This container contains the modal code.
  </div>

  <!-- Move the modal div outside of my-module -->
  <div class="modal fade">
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-body">Modal</div>
      </div>
    </div>
  </div>
</body></code>

By following these solutions, the modal will overlay correctly, ensuring accessibility and proper functionality.
