Bootstrap modal appearing under background


I have used the code for my modal straight from the Bootstrap example, and have included only the bootstrap.js (and not bootstrap-modal.js). However, my modal is appearing underneath the grey fade (backdrop) and is non editable.

Here's what it looks like:

modal hiding behind backdrop

See this fiddle for one way to reproduce this problem. The basic structure of that code is like this:

<body>
    <p>Lorem ipsum dolor sit amet.</p>    

    <div class="my-module">
        This container contains the modal code.
        <div class="modal fade">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-body">Modal</div>
                </div>
            </div>
        </div>
    </div>
</body>
body {
    padding-top: 50px;
}

.my-module {
    position: fixed;
    top: 0;
    left: 0;
}

Any ideas why this is or what I can do to fix this?

If the modal container has a fixed or relative position or is within an element with fixed or relative position this behavior will occur.

Make sure the modal container and all of its parent elements are positioned the default way to fix the problem.

Here are a couple ways to do this:

  1. Easiest way is to just move the modal div so it is outside any elements with special positioning. One good place might be just before the closing body tag </body>.
  2. Alternatively, you can remove position: CSS properties from the modal and its ancestors until the problem goes away. This might change how the page looks and functions, however.

The problem has to do with the positioning of the parent containers. You can easily "move" your modal out from these containers before displaying it. Here's how to do it if you were showing your modal using js:

$('#myModal').appendTo("body").modal('show');

Or, if you launch modal using buttons, drop the .modal('show'); and just do:

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

This will keep all normal functionality, allowing you to show the modal using a button.


I tried all options supplied above but didn't get it to work using those.

What did work: setting the z-index of the .modal-backdrop to -1.

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

Also, make sure that version of BootStrap css and js are the same ones. Different versions can also make modal appearing under background:

For example:

Bad:

<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.0/js/bootstrap.min.js"></script>

Good:

<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>

I have also encountered this problem and none of the solutions worked for me until i figured out i actually don't need a backdrop. You can easily remove the backdrop with the folowing code.

<div class="modal fade" id="createModal" data-backdrop="false">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h4>Create Project</h4>
            </div>
            <div class="modal-body">Not yet made</div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

Note: the data-backdrop attribute needs to be set to false (other options: static or true).


I got it to work by giving a high z-index value to the modal window AFTER opening it. E.g.:

$("#myModal").modal("show");
$("#myModal").css("z-index", "1500");

Solution provided by @Muhd is the best way to do it. But if you are stuck in a situation where changing structure of the page is not an option, use this trick:

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" data-backdrop="false" style="background-color: rgba(0, 0, 0, 0.5);">
<div class="modal-dialog" role="document">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal"
                aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <h4 class="modal-title" id="myModalLabel">Modal title</h4>
        </div>
        <div class="modal-body">...</div>
        <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
        </div>
    </div>
</div>

The trick in here is data-backdrop="false" style="background-color: rgba(0, 0, 0, 0.5);" by removing the default backdrop and create a dummy one by setting background color of the dialog itself with some alpha.

Update 1: As pointed out by @Gustyn that clicking on the background does not close the dialog as is expected. So to achieve that you have to add some java script code. Here is some example how you can achieve this.

$('.modal').click(function(event){
    $(event.target).modal('hide');
});

A but late on this but here is a generic solution -

    var checkeventcount = 1,prevTarget;
    $('.modal').on('show.bs.modal', function (e) {
        if(typeof prevTarget == 'undefined' || (checkeventcount==1 && e.target!=prevTarget))
        {  
          prevTarget = e.target;
          checkeventcount++;
          e.preventDefault();
          $(e.target).appendTo('body').modal('show');
        }
        else if(e.target==prevTarget && checkeventcount==2)
        {
          checkeventcount--;
        }
     });

An other way to approach this is to remove the z-index from the .modal-backdrop in bootstrap.css. This will cause the backdrop to be on the same level as the rest of your body (it will still fade) and your modal to be on top.

.modal-backdrop looks like this

.modal-backdrop {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background-color: #000000;
}

Just add two lines of CSS:

.modal-backdrop{z-index: 1050;}
.modal{z-index: 1060;}

The .modal-backdrop should have 1050 value to set it over the navbar.


I've simply set:

#myModal {
    z-index: 1500;
}

and it works....

For the original question:

.my-module {
    z-index: 1500;
}

Use this in your modal:

data-backdrop="false" 

This problem can often be experienced when using things like gradients in CSS for things like backgrounds or even accordion headers.

Unfortunately, modifying or overriding core Bootstrap CSS is undesirable, and can lead to unwanted side effects. The least intrusive approach is to add data-backdrop="false" but you may notice that the fade effect no longer works as expected.

After following recent releases of Bootstrap, version 3.3.5 seems to resolve this issue with no unwanted side effects.

Download: https://github.com/twbs/bootstrap/releases/download/v3.3.5/bootstrap-3.3.5-dist.zip

Be sure to include the CSS files and JavaScript files from 3.3.5.


This would cover all modals without messing up any of the animations or expected behavior..

$(document).on('show.bs.modal', '.modal', function () {
  $(this).appendTo('body');
});

Hi I had the same issue then I realize that when you using bootsrap 3.1 Unlike in older versions of bootsrap (2.3.2) the html structure of the modal was changed!

you must wrap your modal header body and footer with modal-dialog and modal-content

<div class="modal hide fade">

  <div class="modal-dialog">
    <div class="modal-content">

    **here goes the modal header body and footer**

    </div>
  </div>

 </div>

none of the suggested solutions above worked for me but this technique solved the issue:

$('#myModal').on('shown.bs.modal', function() {
   //To relate the z-index make sure backdrop and modal are siblings
   $(this).before($('.modal-backdrop'));
   //Now set z-index of modal greater than backdrop
   $(this).css("z-index", parseInt($('.modal-backdrop').css('z-index')) + 1);
}); 

I had this issue and the easiest way to fix it was addind z-index greater than 1040 on the modal-dialog div:

<div class="modal-dialog" style="z-index: 1100;">

I believe bootstrap create a div modal-backdrop fade in which in my case has the z-index 1040, so if You put the modal-dialog on top of this, it should not be grey out anymore.


set the z-index .modal to a highest value

For example, .sidebarwrapper has z-index of 1100, so set the z-index of .modal to 1101

.modal {
    z-index: 1101;
}

I have a lighter and better solution..

It could be easily solve through some additional CSS styles..

  1. hide the class .modal-backdrop (auto generated from Bootstrap.js)

    .modal-backdrop
    {
    display:none;
    visibility:hidden; 
    position:relative
    }
    
  2. set the background of .modal to a translucent black backdrop image.

    .modal
    {
    background:url("http://bin.smwcentral.net/u/11361/BlackTransparentBackground.png")
    // translucent image from google images 
    z-index:1100; 
    }
    

This will works best if you have a requirement that needs the modal to be inside an element and not near the </body> tag..


In my case solve it, add this in my stylesheet:

.modal-backdrop{
  z-index:0;
}

with google debugger, can examine element BACKDROP And modify attributes. Goog luck.


in your navbar navbar-fixed-top need z-index = 1041 and also if u use bootstarp-combined.min.css the also change .navbar-fixed-top, .navbar-fixed-bottom z-index to 1041


Change the absolute position to relative.

.modal-backdrop {
    position: relative;
    /* ... */
}

You can also remove the z-index from .modal-backdrop. Resulting css would look like this.

.modal-backdrop {
}
  .modal-backdrop.in {
    opacity: .35;
    filter: alpha(opacity=35); }

I removed modal backdrop.

.modal-backdrop {
    display:none;
}

This is not better solution, but works for me.


what i find is that:

in bootstrap 3.3.0 it's not right,but when in bootstrap 3.3.5 it's right.let's see the code. 3.3.0:

this.$backdrop = $('<div class="modal-backdrop ' + animate + '" />')
    .prependTo(this.$element)

3.3.5

  this.$backdrop = $(document.createElement('div'))
        .addClass('modal-backdrop ' + animate)
        .appendTo(this.$body)

Add this one to you pages. It work for me.

<script type="text/javascript">
    $('.modal').parent().on('show.bs.modal', function (e) { $(e.relatedTarget.attributes['data-target'].value).appendTo('body'); })
</script>

I was fixed this by adding style below to DIV tag

style="background-color: rgba(0, 0, 0, 0.5);"

And add custom css

.modal-backdrop {position: relative;}

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

For me the easiest solution was to put my modal in a wrapper with absolute position and z-index higher than .modal-backdrop. Since modal-backdrop (at least in my case) has z-index 1050:

.my-modal-wrapper {
  position: absolute;
  z-index: 1060;
}
<div class="my-modal-wrapper"></div>


In my case, I had a wrapper with the following:

.wrapper { margin: 0 auto; position:relative; z-index:1;overflow:hidden;}

Only removed the z-index:1 and have no idea why fixed the problem. also for sure removing the relative position did but I needed it.


I resolved my issue by adding data-backdrop="false" to the div:

<div class="modal fade" id="exampleModalCenter" data-backdrop="false" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
