Answer 1

In Bootstrap 3.1.1 they added modal-lg and modal-sm classes. You control the modal size using @media queries like they do. This is a more global way of controlling the modal size.

@media (min-width: 992px) {
    .modal-lg {
        width: 900px;
        height: 900px; /* control height here */
    }
}

Sample code:

<!-- Large modal -->
<button class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-lg">Large modal</button>

<div class="modal fade bs-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      ...
    </div>
  </div>
</div>

<!-- Small modal -->
<button class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">Small modal</button>

<div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-sm">
    <div class="modal-content">
      ...
    </div>
  </div>
</div>

Answer 2

If your modal id is "myModal "

You could try adding a style like:

#myModal 
{
    width: 700px; 
    margin-top: -300px !important;
    margin-left:  -350px !important; 
} 

#myModal .modal-body {
    max-height: 525px;
}

Answer 3

The easiest way to do this is to use the .modal-lg. Add it to the modal-dialog class within the modal container like so:

<div class="modal fade">
    <div class="modal-dialog modal-lg" role="document">
            <div class="modal-content">
                I am now wider!
            </div>
    </div>
</div>

Answer 4

For a size in %, you could do this:

.modal-body
{
   max-height:80%;
}
.modal
{
   height:80%;
   width:70%;
   margin-left: -35%; 
}
@media (max-width: 768px) {
   .modal
   {
    width:90%;
        margin-left: 2%; 
   }
}

Answer 5

altering class model-dialog did the trick for me

.modal-dialog {
    width: 90%;
}

Answer 6

In your css file, add a new class definition:

.higherWider {
    width:970px;
    margin-top:-250px;
}

In your HTML, add higherWider inside the class string for your modal:

<div class="modal hide fade higherWider">

Answer 7

The accepted answer works well, however I would recommend using padding rather than margin. This way you retain the dismiss functionality when you click outside of the modal dialog.

#myModal {
    width: 700px; 
    padding-top: -300px !important;
    padding-left: -350px !important; 
} 

#myModal .modal-body {
    max-height: 525px;
}

Answer 8

css:

.modal-lg, .modal-sm {
    min-width: 90%;
}

code:

<!-- The Modal -->
<div class="modal fade" id="myModal">
    <div class="modal-dialog modal-lg">
        <div class="modal-content">

            <!-- Modal Header -->
            <div class="modal-header">
                <h4 class="modal-title">Modal Heading</h4>
                <button type="button" class="close" data-dismiss="modal">&times;</button>
            </div>

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

            <!-- Modal footer -->
            <div class="modal-footer">
                <button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
            </div>

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

Answer 9

With CSS:

.modal {
    width: 900px;
    margin-left: -450px; // half of the width
}

Answer 10

Following works without viewport breakpoints and also for older bootstrap modals:

#myModal{
   position: fixed;
   left: 10% !important;
   right: 10% !important;
   top: 10% !important;
   width: 80% !important;
   margin: 0 !important;
}

Answer 11

Either of the following solutions worked for me:

1. Applying style="width: 50%; height:50%;" to the div in the modal section with the class="modal-dialog" like so

   <div class="modal-dialog" style="width: 50%; height:50%;">
   

   or

2. Creating a style section like so

    #themodal .modal-dialog{ width:50%; height:50%;}
