Bootstrap Modal Dialog. Can the grid system be use

问题:

I have a Bootstrap modal dialog for which I want to layout the various labels and inputs. I have tried using row/column classes but they do not appear to do anything. What are my options here?

Thanks,
Doug

I got it working ok...http://www.bootply.com/WAwE3QyUdb

Add a col to the container inside the modal-body.

<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <h3>Modal header</h3>
        </div>

        <div class="modal-body">
            <div class="container col-md-12">
                <div class="row">
                    <div class="col-md-3">
                        1st col 3
                    </div>

                     <div class="col-md-3">
                         2nd col 3
                     </div>

                     <div class="col-md-3">
                         3rd col 3</div>
                     </div>
                 </div>
             </div>
         </div>
    </div>
</div>

Just add the row class to your modal as per the code below and then you can divide up your modal as you wish:

<div class="modal-body row">
  <div class="col-md-8">
    <p>Column One content here ... </p>
  </div>
  <div class="col-md-4">
    <p>Column Two content here ... </p>
  </div>
</div>

Tom Rudge's answer inspired me. You don't need to make the container also be a full-width column itself which Matt Dell pointed out will fail linters.

Make the container container-fluid instead!

<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <h3>Modal with container fluid</h3>
        </div>
        <div class="modal-body">
            <div class="container-fluid">
                <div class="row">
                    <div class="col-md-3">
                        <p>
                            1st col 3
                        </p>

You can make the Bootstrap modal responsive by resetting the container widths:

.modal-body {padding: 5px}

.modal-dialog {
@media(min-width: $screen-sm-min){
  width: 600px;
  .container {
    width: 590px;
  }
}

@media(min-width: $screen-md-min){
  width: 800px;
  .container {
    width: 790px;
  }
}

@media(min-width: $screen-lg-min){
  width: 1000px;
  .container {
    width: 990px;
  }
}
}

For Bootstrap 4 you can create a modal container with SCSS.

The .modal-container class should be added to the .modal-dialog

Variables:

$modal-container-max-widths: (
  xs: 90%,
  sm: 540px,
  md: 720px,
  lg: 960px,
  xl: 1200px,
);

Coding:

@mixin make-modal-max-widths-container-width($max-widths: $modal-container-max-widths, $breakpoints: $grid-breakpoints) {
  @each $breakpoint, $modal-container-max-width in $max-widths {
    @include media-breakpoint-up($breakpoint, $breakpoints) {
        max-width: $modal-container-max-width;
    }
  }
}
.modal-container{
   @include make-modal-max-widths-container-width();
}

Some additional CSS is recommended.

.modal-container{
  margin-left: auto;
  margin-right: auto;
  padding-left: ($spacer / 2);
  padding-right: ($spacer / 2);
}
