When using a Bootstrap Modal to display larger versions of thumbnails in a photo gallery, there can be some challenges. The default behavior of Bootstrap is to position the modal at the top of the viewport, which may work fine in most cases. However, if the gallery is being viewed within an iframe, it can cause issues.
Because of this, it becomes necessary to ensure that the modal dialog appears at the same height as the top of the gallery div. While attempting to use CSS to position the modal (top: 123px) may seem like a solution, it falls short when the content above the gallery is frequently changing.
For a more effective approach, it would be ideal to position the modal relative to the gallery itself, along with all its images. This will provide a more stable and accurate placement for the modal.
