Just move the entire modal outside of the rest of your code, to the very bottom. It doesn't need to be nested in any other element, other than the body.

<body>
    <!-- All other HTML -->
    <div>
        ...
    </div>

    <!-- Modal -->
    <div class="modal fade" id="myModal">
        ...
    </div>
</body>

Modal Markup Placement
Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.

Back Button in browser not clearing Bootstrap 5 modal backdrop?
we would have to know how you are doing your routing, where the modal component is located in the routing tree, etc. if the same exact modal component is present in both pages, it’s not going to clear until the show state is set to false. More on reddit.com

Modal with blurry background
When the modal is open, a backdrop div is shown in front of the page, behind the modal. Style the backdrop div to the blur should get what you want e.g., .modal-backdrop { background-color: rgba(255, 255, 255, 0.5); backdrop-filter: blur(10px); } More on reddit.com

Any workaround for this Safari bug with a Bootstrap 4 modal?
This is a problem I have run into before. Neither positioning nor z-index will solve it for you, sadly. The solution is to add the following to the correct parent container of the modal. In this case, the body of the iframe you are jsfiddle is using: -webkit-transform: translate3d(0,0,0); I just tested in your fiddle and this will solve your problem. The use of the webkit prefix will limit the impact of this to only webkit based browsers. More on reddit.com

In my case, I could fix it by adding css for the .modal-backdrop

.modal-backdrop {
  z-index: -1;
}

Although this works, form controls still seem to appear above the backdrop, clicking anywhere dismisses the modal, but it doesn't look great.

A better workaround for me is to bind to the shown event (once the page is loaded) and to correct the z-index property.

$('.modal').on('shown.bs.modal', function() {
  $(this).css("z-index", parseInt($('.modal-backdrop').css('z-index')) + 1);
});

In this case, if you are OK with changing the DOM on modal shown:

$('.modal').on('shown.bs.modal', function() {
  //Make sure the modal and backdrop are siblings (changes the DOM)
  $(this).before($('.modal-backdrop'));
  //Make sure the z-index is higher than the backdrop
  $(this).css("z-index", parseInt($('.modal-backdrop').css('z-index')) + 1);
});

Bootstrap Modal Dialog showing under Modal Background - Rick Strahl's Web Log
September 14, 2016 - The problem is that the .modal-backdrop overlay sits in the root of the DOM tree while the other content is buried in a separate DOM node tree. If anything inside of that tree is relatively positioned, the z-index can no longer be compared effectively. You can try using the following (Bootstrap 4 - in 3 use .modal-dialog instead of .modal-content:
