Bootstrap Modal sitting behind backdrop

So I'm having nearly the exact same problem as @Jamescoo was but I think that my issue is coming from the fact that I have already positioned a couple of DIVs to create a sliding nav panel.

Here's my exact setup replicated: http://jsfiddle.net/ZBQ8U/2/

BONUS: Feel free to grab the code for the sliding panel if you'd like :)

The z-indexes shouldn't conflict and their values would show that they are stacking correctly, but visually they are not.

Once you click the 'Open Modal' button the <div class="modal-backdrop fade in"></div> covers everything! (you'll have to re-run the code to reset it)

I don't know quite how to remedy this one...Any ideas?

Well, in my case the bootstrap 5 modal-backdrop was getting the precedence over the modal itself because my modal div contained the CSS as z-index; auto. Which is where the modal-backdrop was taking precedence over the modal itself.

The problem persists if any ancestor of the [.modal] element has CSS property z-index set. The [.modal] element inherits the CSS z-index from that container element. While the [.modal-backdrop] is inserted into the [body] element dynamically from jQuery code, which has default z-index: 1040 from bootstrap.css.

I came out with two way CSS solution, is better than changing any other behavior of the default event and element.

  1. Set the z-index: 1041 or higher value for the parent element of the [.modal], that ancestor element is causing the [.modal] is underneath the [.modal-backdrop].

Or

  1. Set the z-index: 1039 or lower value for the [.modal-backdrop] in CSS file, if available. Because the HTML [.modal-backdrop] is not available in your code.

[Note: the CSS z-index property may require using !important flag]

[Note: default z-index: 1040 for [.modal-backdrop] is completely depended on bootstrap.css]

For situations regarding frameworks that don't permit you to just move html/css around.

append the modal to the end of the body like

$("#EditModal").modal("show");
$("#EditModal").appendTo("body");

and destroy with

$("#EditModal").remove();

I know it is late, I encountered the same problem but I had to hack it out as below;

 .modal-backdrop {
      /* bug fix - no overlay */    
      display: none;    
}

.modal{
    /* bug fix - custom overlay */   
    background-color: rgba(10,10,10,0.45);
}

if you have nested modals this is the clue :

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

Try remove the backdrop, if you don't realy need it (data-backdrop= "false"):

<div class="modal fade" data-backdrop="false" role="dialog" id="my-modal" aria-labelledby="modal-title">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h3 class="modal-title" id="modal-title">No Backdrop</h3>
                </div>
                <div class="modal-body">
                    <p>
                        Look! No backdrop here!
                    </p>
                </div>
                <div class="modal-footer">
                    <button class="btn btn-default" data-dismiss="modal">Cancel</button>
                    <button class="btn btn-primary">Ok</button>                    </div>
            </div>
        </div>
    </div>

Just remove the backdrop, insert this code in your css file

.modal-backdrop {
      /* bug fix - no overlay */    
      display: none;    
}

In my case one of parents of my modal was animated and had this

.animated {
    -webkit-animation-duration: 1s;
    animation-duration: 1s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
    z-index: 100;
}

The blocker here is animation-fill-mode: both;. I could not just move modal outside, so the solution was to override 'animation-fill-mode' to animation-fill-mode: none;. Animation still worked fine.

I had a similar problem that the fade was not working and the overlay stayed on the page. I had dynamic content added back to the page (refresh on some content only on modal action). I also had this $('#rejectModal-'+itemId).modal('hide') (itemId is dynamic id for multiple modals in a single page for rejecting some information) but the problem was still not gone.

The overlay was staying because my layout was not set to null in the partial view After setting this the problem was gone:

@{ 
    Layout = null;
}

I'm wary of moving the modal content outside its original context: other JS or styles might depend on that context.

However, I doubt there are any scripts or styles that require a specific context for the backdrop.

So my solution is to move the backdrop adjacent to the modal content, forcing it into the same stacking context:

$(document).on('shown.bs.modal', '.modal', function () {
    $('.modal-backdrop').before($(this));
});

It's only a slight deviation from jacoswarts' solution, so thanks for the inspiration!

i encountred this problem, and after investigating my css, the main container (direct child of the body) had: 

position: relative
z-index: 1

the backdrop worked well after i removed those two properties. You may also encounter this problem if the main wraper have a position: fixed

this works for me.

<div class="modal fade" id="modalDecision" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="false">
<div class="modal-dialog modal-sm">
    <div class="modal-content">
        <div class="modal-body text-center">
            <asp:Label runat="server" Height="30px">Please select recovery delivery option</asp:Label>
            <asp:LinkButton ID="btnEmail" CssClass="submit btn btn-primary" Width="100px" runat="server"
                OnClick="ModalRecovery">Email</asp:LinkButton>
            <asp:LinkButton ID="btnText" CssClass="submit btn btn-primary" Width="100px" runat="server"
                OnClick="ModalRecovery">Text</asp:LinkButton>
        </div>
    </div>
</div>


var element = $('#modalDecision');
    // also taken from bootstrap 3 docs
    $(element).on('shown.bs.modal', function (e) {
        // keep in mind this only works as long as Bootstrap only supports 1 modal at a time, which is the case in Bootstrap 3 so far...
        var backDrop = $("<div class='modal-backdrop' style='z-index:-1;opacity:.5'></div>");
        $(element).append($(backDrop));
    });

If you use JQuery, you can use the appendTo() to append the modal to a specific element, in this case, the , in most case, a simple one line can move your modal on top of the backdrop regardless where your modal div's position

$("#myModal").appendTo("body");

here's the reference of the JQuery appendTo function: http://api.jquery.com/appendto/

I updated it to your fiddle http://jsfiddle.net/ZBQ8U/240/

In Addition to all answers here, i found out, that the bootstrap4 "animated fadeIn" is also causing this error (not clickable modal behind background):

check if your modal is in the following parent tag (bootstrap animation)

<div class="animated fadeIn"></div>

I removed this tag - solved the problem for me.

First make sure the modal is not in any parent div. Then add $('#myModal').appendTo("body")

It worked fine for me.

For those using ASP.NET MVC,

Needing to move the modal div just before the </body> tag but can't do it because you are using a Layout page

Define a section in you _Layout.cshtml file just before the body tag, eg:

... some html in layout page ...
@RenderSection("bottomHTML", required: false)
</body>
</html>

Then in your view

@section bottomHTML 
{
<div class="modal fade" id="myModalID" role="dialog" tabindex="-1" aria-labelledby="demo-default-modal" aria-hidden="true">
... rest of the modal div HTML ...
}

This way, the modal HTML will be rendered before the body tag and the modal now should be displayed correctly..

You could use this : 

<div
  class="modal fade stick-up disable-scroll"
  id="filtersModal"
  tabindex="-1"
  role="dialog"
  aria-labelledby="filtersModal"
  aria-hidden="false"
  style="background-color: rgba(0, 0, 0, 0.5);" data-backdrop="false"
>
....
</div>

Adding style="" and data-backdrop false would fix it.

if we cannot delete backdrop and/or we have component framework such angular or vue we cannot move modal to the root. i did this trick: put my custom modal-backdrop container(with aditional class) as sibling for modal-dialog container and added some css

<div bsModal #moneyModal="bs-modal" class="modal fade" tabindex="-1" role="dialog">
    <!-- magic container-->
    <div class="modal-holder modal-backdrop" (click)="moneyModal.hide()"></div>
    <div class="modal-dialog modal-sm" role="document">
        <div class="modal-content">
            <div class="modal-body">
                ....
            </div>
        </div>
    </div>
</div>

and css

.modal-backdrop{z-index: -1}// or you can disable modal-backdrop
.modal-holder.modal-backdrop{z-index: 100}
.modal-holder + .modal-dialog {z-index: 1000}

None of the answers worked well enough for me. The problem appeared to lie where the modal windows needs to be outside of the body.and it is not best

So this code done the job just prefectly:

$('.modal ').insertAfter($('body'));

$('#product_' + product_id + ' .modal ').insertAfter($('body'));

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>

Demo

They hint at this solution in the documentation.

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.

Many times , you cannot move the modal outside as this affects your design structure.

The reason the backdrop comes above your modal is id the parent has any position set.

A very simple way to solve the problem other then moving your modal outside is move the backdrop inside structure were you have your modal. In your case, it could be

$(".modal-backdrop").appendTo("main");

Note that this solution is applicable if you have a definite strucure for your application and you cant just move the modal outside as it will go against the design structure

Put this code wherever you want

$('.modal').on('shown.bs.modal', function () {
    var max_index = null;
    $('.modal.fade.in').not($(this)).each(function (index , value){
        if(max_index< parseInt( $(this).css("z-index")))
            max_index = parseInt( $(this).css("z-index"));
    });
    if (max_index != null) $(this).css("z-index", max_index + 1);
});

If you can't put the modal to the root (if your use angular and the modal is in a controller for example), modifying bootstrap or using js is obviously a bad solution.

so saying you have your website structure:

//not working
<div>
    <div>
        <div>
            <modal></modal>
        </div>
    </div>
</div>

open your code inspector and move the modal to the root, it should be working (but no where you want):

//should be working
<div>
    <div>
        <div>

        </div>
    </div>
</div>
<modal></modal>

now put it in the first div and check if it's working: if yes check the next child until it's not working and find the div that is the problem;

//should be working
<div>
    <div>
        <div>

        </div>
    </div>
    <modal></modal>
</div>

Once you know which div is the problem you can play with the css display and position to make it work.

everyone has a different structure but in my case setting a parent to display: table; was the solution

Since I don't have the chance to move the modal markup since i added it in a partial template within a conditional what worked for me is add CSS bellow

.modal.fade {
    display: none;
}

Then, when boostrap add class "in" through js apply display: block and everything works fine.

I was fighting with the same problem some days... I found three posible solutions, but i dont know, which is the most optimal, if somebody tell me, i will be grateful.

the modifications will be in bootstrap.css

Option 1: 

.modal-backdrop {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 1040; <- DELETE THIS LINE
  background-color: #000000;
}

Option 2:

.modal-backdrop {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: -1; <- MODIFY THIS VALUE BY -1
  background-color: #000000;
}

Option 3:

/*ADD THIS*/
.modal-backdrop.fade.in {
    z-index: -1;
}

I used the option 2.

Another resolution for this problem is to add z-index: 0; to .modal-backdrop class in your bootstrap-dialog.css file if you don't want to modify bootstrap.css.
