Bootstrap 4 card-deck with number of columns based on viewport

Question

I\'m trying to implement the card-deck feature in bootstrap 4 to make all of my cards the same height.

The examples that bootstrap provides show 4 nice cards, but it

Answer 1

Here's a solution with Sass to configure the number of cards per line depending on breakpoints: https://codepen.io/migli/pen/OQVRMw

It works fine with Bootstrap 4 beta 3

// Bootstrap 4 breakpoints & gutter
$grid-breakpoints: (
    xs: 0,
    sm: 576px,
    md: 768px,
    lg: 992px,
    xl: 1200px
) !default;

$grid-gutter-width: 30px !default;

// number of cards per line for each breakpoint
$cards-per-line: (
    xs: 1,
    sm: 2,
    md: 3,
    lg: 4,
    xl: 5
);

@each $name, $breakpoint in $grid-breakpoints {
    @media (min-width: $breakpoint) {
        .card-deck .card {
            flex: 0 0 calc(#{100/map-get($cards-per-line, $name)}% - #{$grid-gutter-width});
        }
    }
}

EDIT (2019/10)

I worked on another solution which uses horizontal lists group + flex utilities instead of card-deck:

It's an easy solution to organize any kind of elements into responsive grid
