Containment) は、ウェブページの表示性能を向上させるために、開発者がページの任意のサブツリーをページのそれ以外の部分から独立させることができます。もしページの一部が独立していることをブラウザーが知っていれば、レンダリングを最適化し、表示性能を向上させることができます。</p> <p><a href="/ja/docs/Web/CSS/contain"><code>contain</code></a> と <a href="/ja/docs/Web/CSS/content-visibility"><code>content-visibility</code></a> プロパティを使うことで、開発者はユーザーエージェントに、要素がコンテンツをすべて表示すべきかどうか、また画面外にあるときにコンテンツを表示すべきかどうかを知らせることができます。ユーザーエージェントは、必要に応じて要素に拘束を適用し、必要なときまでレイアウトやレンダリングを延期することができます。</p> <p>このガイドでは、 CSS 拘束の基本的な目的と、 <code>contain</code> と <code>content-visibility</code> を活用してユーザー体験を向上させる方法について記述しています。</p></div><section aria-labelledby="基本的な例"><h2 id="基本的な例"><a href="#基本的な例">基本的な例</a></h2><div class="section-content"><p>ウェブページには、論理的には互いに独立した複数の節が含まれていることがよくあります。 CSS 拘束により、レンダリング時に他のセクションを本当に独立して扱うことができます。</p> <p>例えば、ブログは通常複数の記事を含み、それぞれが下記のマークアップのように見出しとコンテンツを含みます。</p> <div class="code-example"><div class="example-header"><span class="language-name">html</span></div><pre class="brush: html notranslate"><code><h1>私のブログ</h1> <article> <h2>良い記事の見出し</h2> <p>コンテンツはこちら。</p> </article> <article> <h2>他の記事の他の見出し</h2> <p>さらなるコンテンツはこちら。</p> </article> </code></pre></div> <p>CSS では、 <a href="/ja/docs/Web/CSS/contain"><code>contain</code></a> プロパティに <code>content</code> という値をそれぞれの記事に適用します。 <code>content</code> の値は <code>contain: layout paint style</code> の一括指定です。</p> <div class="code-example"><div class="example-header"><span class="language-name">css</span></div><pre class="brush: css notranslate"><code>article { contain: content; } </code></pre></div> <p>論理的には、それぞれの記事はページ上の他の記事から独立しています。この情報は通常、ウェブ開発者がページを作成する際に知っていることであり、明白なことです。しかし、ブラウザーはコンテンツの意図を知らないので、記事や他のコンテンツの節が完全に自己完結しているとみなすことはできません。</p> <p>このプロパティは、このことをブラウザーに説明し、パフォーマンスの最適化を明示的に許可する方法を提供します。これは、要素の内部レイアウトがページの他の部分とは完全に別個のものであり、要素に関するすべてがその境界の内側に描画されることをブラウザーに指示します。目に見えてはみ出すものはありません。</p> <p>それぞれの <code><article></code> に <code>contain: content</code> を設定することで、このことを指示しています。つまり、それぞれの記事が独立していることをブラウザーに指示したのです。ブラウザーはこの情報を使用して、それぞれの <code><article></code> コンテンツをどのようにレンダリングするかを決定することができます。例えば、表示可能領域の外にある記事はレンダリングしないかもしれません。</p> <p>記事がページの終わりに追加されたとき、ブラウザーはレイアウトを再計算したり、先行するコンテンツを再描画する必要はありません。また、拘束要素のサブツリーの外側の領域に触れる必要もありません。しかし、ボックスモデルのプロパティが依存関係にある場合、ブラウザーはレイアウトを再計算し、再描画する必要があります。例えば、 <code><article></code> のサイズがコンテンツに依存するようにスタイル設定されている場合（例えば <code>height: auto</code> など）、ブラウザーはサイズが変化することを考慮する必要があります。</p></div></section><section aria-labelledby="主要概念と用語"><h2 id="主要概念と用語"><a

<p>レイアウトは通常、文書全体がスコープになっています。つまり、文書全体の中から 1 つの要素を動かしただけで、すべてが動かされたかのように扱われます。 <code>contain: layout</code> を使うことで、ブラウザーに対して必要な要素のみを伝えることができます。要素の中にあるものはすべてその要素にスコープされ、ページの他の部分には影響せず、包含ボックスは独立した<a href="/ja/docs/Web/CSS/CSS_display/Introduction_to_formatting_contexts">整形コンテキスト</a>を確立します。</p> <p>加えて以下のことが言えます。</p> <ul> <li><a href="/ja/docs/Web/CSS/float"><code>float</code></a> レイアウトは指定した要素の内部で独立して行われます。</li> <li>レイアウト拘束の境界でマージンが相殺されることはありません。</li> <li>レイアウトのコンテナーは <code>absolute</code>/<code>fixed</code> で位置指定された子孫要素の<a

<code>paint</code> 拘束にも <code>layout</code> 拘束と同じことが当てはまります（上記を参照）。</p> <p>もうひとつの利点は、包含ボックスが画面外にある場合、ブラウザーはその内包する要素を描く必要がないことです — これらはそのボックスによって完全に内包されているので、画面外にあるに違いないからです。</p> <h4

href="/ja/docs/Web/CSS/contain-intrinsic-size"><code>contain-intrinsic-size</code></a> または個別指定プロパティ <a href="/ja/docs/Web/CSS/contain-intrinsic-width"><code>contain-intrinsic-width</code></a> および <a href="/ja/docs/Web/CSS/contain-intrinsic-height"><code>contain-intrinsic-height</code></a> の順に要素のサイズを指定する必要があります。サイズが設定されていない場合、要素はほとんどの場合ゼロサイズになるというリスクがあります。</p> <div class="code-example"><div

id="特別な値">特別な値</h4> <p><code>contain</code> には 2 つの特別な値があり、最初の 3 つまたは 4 つすべての種類の拘束を一括指定することができます。</p> <ul> <li><code>content</code></li> <li><code>strict</code></li> </ul> <p>1 つ目は上記の例で既に見ました。 <code>contain: content</code> を使用すると、 <code>layout</code>、<code>paint</code>、<code>style</code> の拘束が有効になります。 <code>size</code> を外しているので、広く適用しても安全な値です。</p> <p><code>contain: strict</code> 宣言は、 <code>contain: size layout paint style</code> 宣言（4 つのスペースで区切られた値を記載する）と同じ動作をし、ほとんどの拘束を提供します。これは <code>size</code> という拘束を適用するために使用することができます。子要素のサイズに依存するため、ボックスのサイズがゼロになってしまう危険性があります。</p> <p>このリスクを避けるために、 <code>strict</code> を使用するときは常にサイズを設定します。</p> <div class="code-example"><div class="example-header"><span class="language-name">css</span></div><pre class="brush: css

<code>layout</code> 拘束と同じことが当てはまります（上記を参照）。</p>\n<p>もうひとつの利点は、包含ボックスが画面外にある場合、ブラウザーはその内包する要素を描く必要がないことです — これらはそのボックスによって完全に内包されているので、画面外にあるに違いないからです。</p>\n<h4 id=\"サイズ拘束\">サイズ拘束</h4>\n<div

<code>layout</code>、<code>paint</code>、<code>style</code> の拘束が有効になります。 <code>size</code> を外しているので、広く適用しても安全な値です。</p>\n<p><code>contain: strict</code> 宣言は、 <code>contain: size layout paint style</code> 宣言（4 つのスペースで区切られた値を記載する）と同じ動作をし、ほとんどの拘束を提供します。これは <code>size</code> という拘束を適用するために使用することができます。子要素のサイズに依存するため、ボックスのサイズがゼロになってしまう危険性があります。</p>\n<p>このリスクを避けるために、 <code>strict</code>
