Cards

Cards(カード)は,複数のバリエーションとオプションで柔軟で拡張可能なコンテナを提供します。

About

card は柔軟で拡張ができるコンテナです。headers や footers のオプション, 多様なコンテンツ, 背景色, 表示オプション が含まれています。
Bootstrap3の panels, wells, thumbnails は card に置きかわります。これらのコンポーネントの機能は card のクラスとして利用できます。

Example

カードは少ないマークアップとスタイルで構築されていますが, 多くのカスタマイズが可能です。
Flexboxで構築されているため, 簡単に配置ができ, 他のコンポーネントと組み合わせ可能です。 デフォルトでは margin の設定がないので, 必要に応じて spacing utilities を使用します。

以下は,幅が固定されたカードの例です。カードには固定幅がないので, 親要素の幅に広がります。これは sizing options でカスタマイズ可能でし。

Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .sr-only class.

Border

Card columns can also be extended and customized with some additional code. Shown below is an extension of the .card-columns class using the same CSS we use—CSS columns— to generate a set of responsive tiers for changing the number of columns.

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