Bootstrap 4 - Responsive cards in card-columns

I'm playing with Bootstrap 4 and I can't find a solution to add responsiveness to cards while in a div with class="card-columns" (this class applies a Masonry-like effect to the cards inside the div having this class).

In Bootstrap 3 it was easy to style and make "cards" responsive since it was possible to apply something like class="col-md-3 col-sm-6 col-xs-12" to a div containing thumbnail , caption , etc.

How to have the same effect while using cards in Bootstrap 4?

Here is the HTML:

<body>

<div class="container-fluid">
    <div class="row">

        <div class="col-md-4 hidden-sm-down" id="map_container">
            <p>here we put the map</p>
        </div>

        <div class="col-md-8 col-sm-12 right_box">

            <div class="row">

                // here there's code for navbar

            </div><!-- row -->

            <div class=row">
                <div class="card-columns">
                    <?php
                    // Create and check connection
                    
                    if ($result->num_rows > 0) {

                        // output card design
                        while($row = $result->fetch_assoc()) {

                            echo '<div class="card">
                                    <img class="card-img-top" src="dance' . $row["id"] . '.jpg" alt="' . $row["name"] . '">
                                    <div class="card-block">
                                        <h4 class="card-title">' . $row["name"] . '</h4>
                                        <p class="card-text">Text. Card content.</p>
                                    </div>
                                    <div class="card-footer text-muted">
                                        <ul class="list-inline">
                                            <li><i class="fa fa-user"></i></li>
                                            <li>14</li>
                                        </ul>
                                    </div>
                                  </div><!-- card -->';
                        }
                    } else {
                        echo "0 results";
                    }

                    $conn->close();
                    ?>
                </div><!-- container card-columns -->
            </div><!-- row -->
        </div><!-- col-md-8 right_box -->
    </div><!-- row -->
</div><!-- container-fluid -->
</body>

And here is the CSS I've used:

#map_container {
background-image: url(map.png);
height: 100vh;
}

.right_box {
-webkit-box-shadow: -2px 0px 2px 0px rgba(0,0,0,0.75);
-moz-box-shadow: -2px 0px 2px 0px rgba(0,0,0,0.75);
box-shadow: -2px 0px 2px 0px rgba(0,0,0,0.75);
}

.card {
border-radius: 0 !important;
border: 0 none;
-webkit-box-shadow: 0px 2px 5px 0px rgba(0,0,0,0.5);
-moz-box-shadow: 0px 2px 5px 0px rgba(0,0,0,0.5);
box-shadow: 0px 2px 5px 0px rgba(0,0,0,0.5);
margin-left: 1px;
margin-right: 1px;
}

.card-img-top {
width: 100%;
border-radius: 0 !important;
}

.card-columns {
padding-top: 15px;
}

Given below are two images to make my situation clearer:

Large screen

Smaller screen

I'd like cards to stack up vertically on smaller screens.

Thanks for your suggestions!

Update 2019 - Bootstrap 4

You can simply use the SASS mixin to change the number of cards across in each breakpoint / grid tier.

.card-columns {
  @include media-breakpoint-only(xl) {
    column-count: 5;
  }
  @include media-breakpoint-only(lg) {
    column-count: 4;
  }
  @include media-breakpoint-only(md) {
    column-count: 3;
  }
  @include media-breakpoint-only(sm) {
    column-count: 2;
  }
}

SASS Demo: http://www.codeply.com/go/FPBCQ7sOjX

Or, CSS only like this...

@media (min-width: 576px) {
    .card-columns {
        column-count: 2;
    }
}

@media (min-width: 768px) {
    .card-columns {
        column-count: 3;
    }
}

@media (min-width: 992px) {
    .card-columns {
        column-count: 4;
    }
}

@media (min-width: 1200px) {
    .card-columns {
        column-count: 5;
    }
}

CSS-only Demo: https://www.codeply.com/go/FIqYTyyWWZ

Bootstrap 4 (4.0.0-alpha.2) uses the css property column-count in the card-columns class to define how many columns of cards would be displayed inside the div element.
But this property has only two values:

  • The default value 1 for small screens ( max-width: 34em )
  • The value 3 for all other sizes ( min-width: 34em )

Here's how it is implemented in bootstrap.min.css :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count:3;
        -moz-column-count:3;
        column-count:3;
        ⋮
    }
    ⋮
}

To make the card stacking responsive, you can add the following media queries to your css file and modify the values for min-width as per your requirements :

@media (min-width: 34em) {
    .card-columns {
        -webkit-column-count: 2;
        -moz-column-count: 2;
        column-count: 2;
    }
}

@media (min-width: 48em) {
    .card-columns {
        -webkit-column-count: 3;
        -moz-column-count: 3;
        column-count: 3;
    }
}

@media (min-width: 62em) {
    .card-columns {
        -webkit-column-count: 4;
        -moz-column-count: 4;
        column-count: 4;
    }
}

@media (min-width: 75em) {
    .card-columns {
        -webkit-column-count: 5;
        -moz-column-count: 5;
        column-count: 5;
    }
}

I have created a Cards Layout - 3 cards in a row using Bootstrap 4 / CSS3 (of course its responsive). The following example uses basic Bootstrap 4 classes such as container , row , col-x , list-group and list-group-item . Thought to share here if someone is interested in this sort of a layout.

If you are using Sass:

$card-column-sizes: (
    xs: 2,
    sm: 3,
    md: 4,
    lg: 5,
);

@each $breakpoint-size, $column-count in $card-column-sizes {
    @include media-breakpoint-up($breakpoint-size) {
      .card-columns {
        column-count: $column-count;
        column-gap: 1.25rem;

        .card {
          display: inline-block;
          width: 100%; // Don't let them exceed the column width
        }
      }
    }
}

I realize this question was posted a while ago; nonetheless, Bootstrap v4.0 has card layout support out of the box. You can find the documentation here:Bootstrap Card Layouts .

I've gotten back into using Bootstrap for a recent project that relies heavily on the card layout UI. I've found success with the following implementation across the standard breakpoints:

 <link href="https://unpkg.com/tachyons@4.10.0/css/tachyons.min.css" rel="stylesheet"/> <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="flex justify-center" id="cars" v-cloak> <!-- RELEVANT MARKUP BEGINS HERE --> <div class="container mh0 w-100"> <div class="page-header text-center mb5"> <h1 class="avenir text-primary mb-0">Cars</h1> <p class="text-secondary">Add and manage your cars for sale.</p> <div class="header-button"> <button class="btn btn-outline-primary" @click="clickOpenAddCarModalButton">Add a car for sale</button> </div> </div> <div class="container pa0 flex justify-center"> <div class="listings card-columns"> <div class="card mv2"> <img src="https://farm4.staticflickr.com/3441/3361756632_8d84aa8560.jpg" class="card-img-top" alt="Mazda hatchback"> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content. </p> <a href="#" class="btn btn-primary">Go somewhere</a> </div> <div class="card-footer"> buttons here </div> </div> <div class="card mv2"> <img src="https://farm4.staticflickr.com/3441/3361756632_8d84aa8560.jpg" class="card-img-top" alt="Mazda hatchback"> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content. </p> <a href="#" class="btn btn-primary">Go somewhere</a> </div> <div class="card-footer"> buttons here </div> </div> <div class="card mv2"> <img src="https://farm4.staticflickr.com/3441/3361756632_8d84aa8560.jpg" class="card-img-top" alt="Mazda hatchback"> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content. </p> <a href="#" class="btn btn-primary">Go somewhere</a> </div> <div class="card-footer"> buttons here </div> </div> <div class="card mv2"> <img src="https://farm4.staticflickr.com/3441/3361756632_8d84aa8560.jpg" class="card-img-top" alt="Mazda hatchback"> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content. </p> <a href="#" class="btn btn-primary">Go somewhere</a> </div> <div class="card-footer"> buttons here </div> </div> <div class="card mv2"> <img src="https://farm4.staticflickr.com/3441/3361756632_8d84aa8560.jpg" class="card-img-top" alt="Mazda hatchback"> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content. </p> <a href="#" class="btn btn-primary">Go somewhere</a> </div> <div class="card-footer"> buttons here </div> </div> </div> </div> </div> </div>

After trying both the Bootstrap .card-group and .card-deck card layout classes with quirky results at best across the standard breakpoints, I finally decided to give the .card-columns class a shot. And it worked!

Your results may vary, but .card-columns seems to be the most stable implementation here.

Another late answer, but I was playing with this and came up with a general purpose Sass solution that I found useful and many others might as well. To give an overview, this introduces new classes that can modify the column count of a .card-columns element in very similar ways to columns with .col-4 or .col-lg-3 :

@import "bootstrap";

$card-column-counts: 1, 2, 3, 4, 5;

.card-columns {
    @each $column-count in $card-column-counts {
        &.card-columns-#{$column-count} {
            column-count: $column-count;
        }
    }

    @each $breakpoint in map-keys($grid-breakpoints) {
        @include media-breakpoint-up($breakpoint) {
            $infix: breakpoint-infix($breakpoint, $grid-breakpoints);
            @each $column-count in $card-column-counts {
                &.card-columns#{$infix}-#{$column-count} {
                    column-count: $column-count;
                }
            }
        }
    }
}

The end result of this is if you have the following:

<div class="card-columns card-columns-2 card-columns-md-3 card-columns-xl-4">
   ...
</div>

Then you would have 2 columns by default, 3 for medium devices and up and 4 for xl devices and up. Additionally if you change your grid breakpoints this will automatically support those, and the $card-column-counts can be overridden to change the allowed numbers of columns.
