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:
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;
}
}

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;
}
}
