<code>visibility: collapse</code> を設定することで、フレックスアイテムが折り畳まれた場合の動作が詳細に規定されています。 <a href="/ja/docs/Web/CSS/visibility"><code>visibility</code></a> プロパティの MDN ドキュメントを参照してください。仕様では、以下のように動作を説明しています。</p> <blockquote> <p>「フレックスアイテムに visibility:collapse を指定すると、折り畳まれたフレックスアイテムになり、table-row や table-column の visibility:collapse と同様の効果が得られます。折り畳まれたフレックスアイテムはレンダリングから完全に削除されますが、フレックス行の交差軸の寸法を安定させる「支柱」が残ります。したがって、フレックスコンテナーにフレックス行が 1 つしかない場合、アイテムの折り畳み状態を動的に変化させると、フレックスコンテナーの主軸の寸法が変更されることがありますが、交差軸の寸法には影響しないことが保証されているため、ページの残りのレイアウトが「ぐらつく」ことはありません。ただし、フレックスの行の折り返しは折り畳み後に再実行されるため、複数の行を持つフレックスコンテナーの交差軸の寸法は変更される場合もあれば、変更されない場合もあります。" - <a href="https://www.w3.org/TR/css-flexbox-1/#visibility-collapse" class="external" target="_blank">Collapsed items</a></p> </blockquote> <p>この動作は、 JavaScript を使用してフレックスアイテムを対象にし、コンテンツの表示・非表示を行う場合などに便利です。仕様書の例では、そのようなパターンの一つを示しています。</p> <p>次のライブサンプルでは、折り返しのないフレックスコンテナーを使用しています。3 番目のアイテムは他のアイテムよりも内容物が多いのですが、 <code>visibility: collapse</code> に設定されているため、フレックスコンテナーはこのアイテムを表示するために必要な高さの<em>支柱</em>を保持しています。CSS から <code>visibility: collapse</code> を削除したり、値を <code>visible</code> に変更したりすると、アイテムが現れ、折り畳まれていないアイテムに空間が再分配されますが、フレックスコンテナーの高さは変わりません。</p> <div class="notecard note"> <p><strong>メモ:</strong> Chrome や Safari では折りたたまれている部分は非表示として扱われるため、以下の 2 つの例は Firefox を使用してください。</p>

<p>つまり、アイテムが最初の行とは別の行になってしまう可能性があるのです。アイテムを表示したり隠したりすると、アイテムが別の行になってしまうこともあります。</p> <p>次のライブサンプルでは、この動作を作成しました。折り畳まれたアイテムの位置に基づいて、引き伸ばされている行が変化している様子がわかります。2
