8- Responsive .card-columns

Angenommen, Sie möchten ein  Responsive .card-columns , das nach dem folgende Grundsatz funktioniert : Die Elemente  Card werden auf fünft Säulen anzeigen wenn das Gerat die Größe von  xl hat oder àuf 4 Säulen anzeigen wenn das Gerat die Größe von lg hat, auf 3 Säule anzeigen wenn die Größe des Gerat  md ist, auf 2 Säulen anzeigen wenn die Größe des Gerat  sm ist, auf 1 Säule anzeigen wenn die Größe des Gerat  Extra-Small ist.
Sie haben 2 Wege um das zu machen:
  1. SASS Mixin verwenden.
  2. CSS verwenden.
SASS mixin
.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;
    }
}
CSS
@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;
    }
}
