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?
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>
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.
Although the z-index of the .modal is higher than that of the .modal-backdrop, that .modal is in a parent div #content-wrap which has a lower z-index than .modal-backdrop (z-index: 1002 vs z-index: 1030).
Because the parent has lower z-index than the .modal-backdrop everything in it will be behind the modal, irrespective of any z-index given to the children.
If you remove the z-index you have set on both the body div#fullContainer #content-wrap and also on the #ctrlNavPanel, everything seems to work ok.
body div#fullContainer #content-wrap {
background: #ffffff;
bottom: 0;
box-shadow: -5px 0px 8px #000000;
position: absolute;
top: 0;
width: 100%;
}
#ctrlNavPanel {
background: #333333;
bottom: 0;
box-sizing: content-box;
height: 100%;
overflow-y: auto;
position: absolute;
top: 0;
width: 250px;
}
NOTE: I think that you may have initially used z-indexes on the #content-wrap and #ctrlNavPanel to ensure the nav sits behind, but that's not necessary because the nav element comes before the content-wrap in the HTML, so you only need to position them, not explicitly set a stacking order.
EDIT As Schmalzy picked up on, the links are no longer clickable. This is because the full-container is 100% wide and so covers the navigation. The quickest way to fix this is to place the navigation inside that div:
<div id="fullContainer">
<aside id="ctrlNavPanel">
<ul class="nav-link-list">
<li><label>Menu</label></li>
<li><a href="/"><span class="fa fa-lg fa-home"></span> Home</a></li>
<li><a><span class="fa fa-lg fa-group"></span>About Us</a></li>
<li><a><span class="fa fa-lg fa-book"></span> Contacts</a></li>
</ul>
</aside>
<div id="content-wrap">
...
</div>
</div>
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);
});
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'));
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 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.
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>
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.
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}
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.
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..
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!
just remove z-index: 1040;
from this file bootstrap.css class .modal-backdrop
I was missing the follow html
<div class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
added it and worked without problems
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 Found that applying ionic framework (ionic.min.cs) after bootstrap coursing this issue for me.
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
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);
});
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
just move your modal outside of all div contents, place it mostly prior to closing of body.
First make sure the modal is not in any parent div. Then add $('#myModal').appendTo("body")
It worked fine for me.
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.
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/
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));
});
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
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;
}
