Bootstrap Modal popping up but has a “tinted” page

Question

I am using bootstrap to set up a modal popup. When a button is clicked, the modal dialog opens, but the entire page is slightly "tinted", and I can't interact with the modal (the page essentially freezes). Do you know why this would be? Here is the code:

button:

<a class="add-list-button-no-margin opener" id="id" data-toggle="modal" href="#myModal" style="color: white; font:14px / 14px 'DINMedium','Helvetica Neue',Helvetica,Arial,sans-serif;">Play my city</a>

modal:

<div id="myModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
      <div class="modal-dialog">
        <div class="modal-content">

          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
            <h4 class="modal-title" id="myModalLabel">Congratulations!</h4>
          </div>
          <div class="modal-body">
            <h4>Text in a modal</h4>
            <p>Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>

            <h4>Popover in a modal</h4>
            <p>This <a href="#" role="button" class="btn btn-default popover-test" title="A Title" data-content="And here's some amazing content. It's very engaging. right?">button</a> should trigger a popover on click.</p>

            <h4>Tooltips in a modal</h4>
            <p><a href="#" class="tooltip-test" title="Tooltip">This link</a> and <a href="#" class="tooltip-test" title="Tooltip">that link</a> should have tooltips on hover.</p>

            <hr>

            <h4>Overflowing text to show optional scrollbar</h4>
            <p>body</p>
          </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><!-- /.modal-content -->
      </div><!-- /.modal-dialog -->
    </div><!-- /.modal -->

Answer 1

I found a good fix for this problem here:

https://stackoverflow.com/a/18764086

Add -webkit-transform: translateZ(0) to the position: fixed element. This forces Chrome to use hardware acceleration to continuously paint the fixed element and avoid this bizarre behavior.

Answer 2

I fixed this problem by moving all modal html to the bottom of my file! Nothing else worked. Only the button to open the modal is within the rest of the html. This could have something to do with body tag declarations but I don't have time to worry about it.

Answer 3

Ok, so I figured out the issue.

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

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 .

This is what I did, and it worked.

Answer 4

If you're using ASP.NET, make sure you place the modal's div block inside a <asp:Content ContentPlaceHolderID="BottomOfForm" runat="server">.

Answer 5

I ran into this as well and found this exact phenomenon occurs with the screen freezing after clicking the button to open a Modal and found this was due to an unclosed that I accidently deleted.

When I added the closing , the Modal Popup started working again.

Answer 6

This happened to me, and it took ages to diagnose. If it happens to you, add this to your css:

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

EDIT: You may need more specificity for this setting to be picked up. As Nick Spoon suggests, you can use

body.modal-open div.modal-backdrop { 
    z-index: 0; 
}

And you may need to add more qualifiers, depending on what the rest of your CSS is doing. You can also use !important, but that's just sweeping the problem under the rug.
