Why is My Bootstrap Modal Hiding Behind the Backdrop?

Fixing Modal Hiding Behind Backdrop

Despite following Bootstrap's modal example and including only bootstrap.js, users have encountered an issue where the modal appears underneath the background fade. This problem can be attributed to the positioning of the modal container and its parent elements.

Causes and Solutions

Bootstrap modals require the modal container and all its ancestors to have the default positioning (static). However, when the modal container or its parent elements are positioned as fixed or relative, the modal will be rendered below the backdrop.

To rectify this, there are two options:

1. Move the Modal DIV: Remove the modal DIV from elements with fixed or relative positioning. Place it right before the closing tag. This method ensures the correct positioning of the modal.
2. Remove Positioning Properties: Remove position: CSS properties from the modal and its ancestors until the modal appears correctly. However, this may affect the appearance and functionality of other elements on the page.

Once the correct positioning is established, the modal will appear above the backdrop as intended.
