Skeleton
| Prop | 型 | 既定値 | 説明 |
|---|---|---|---|
variant | "pulse" | "shimmer" | "none" | "pulse" | プレースホルダーのアニメーション。動きを減らす設定では、アニメーションとコンテンツ表示時の動きを無効にします。 |
circle | boolean | false | 長方形の代わりに円形のプレースホルダーを描画します。 |
height | number | string | — | プレースホルダーの高さ。数値はピクセルとして扱います。 |
loading | boolean | true | falseで同じラッパー内のchildrenを表示し、寸法とrefを維持します。選択したスタイルシートが表示時のアニメーションを適用します。 |
width | number | string | — | プレースホルダーの幅。数値はピクセルとして扱います。 |
children | ReactNode | — | loadingがfalseになったときに描画する実際の内容。 |
render | ReactElement | ((props, state) => ReactElement) | — | 動作とアクセシビリティの接続を維持したまま、描画する要素を置き換えます。 |

アクセシビリティ
Skeletonは、読み込み中もコンテンツ表示時も同じラッパーを維持します。読み込み中のプレースホルダーはaria-hiddenとし、読み込み後のchildrenはネイティブのセマンティクスを維持します。pulse、shimmer、noneから選びます。動きを減らす設定ではアニメーションを無効にします。装飾用スケルトンごとにライブステータスを付けず、囲む領域で読み込みを説明してください。
