Colonnes

Colonnes réactives même hauteur (CSS ou SASS uniquement)

Vous devez ajouter une div avec la classe .row-height à l'intérieur de la ligne et ajouter également .col-height aux colonnes. Si vous souhaitez limiter l'effet à une requête multimédia .row-height , utilisez simplement les .row-height responsive .row-height et .col-height : par exemple .row-sm-height avec .col-sm-height .

Version CSS:

.row-height {
  display: table;
  table-layout: fixed;
  height: 100%;
  width: calc(100% + 30px);
}
.col-height {
  display: table-cell;
  float: none;
  height: 100%;
}
.col-top {
  vertical-align: top;
}
.col-middle {
  vertical-align: middle;
}
.col-bottom {
  vertical-align: bottom;
}

@media (min-width: 480px) {
  .row-xs-height {
    display: table;
    table-layout: fixed;
    height: 100%;
    width: 100%;
  }
  .col-xs-height {
    display: table-cell;
    float: none;
    height: 100%;
  }
  .col-xs-top {
    vertical-align: top;
  }
  .col-xs-middle {
    vertical-align: middle;
  }
  .col-xs-bottom {
    vertical-align: bottom;
  }
}
