} .padding-lg { padding: 0.8rem; } } </code></pre></div> <p>2 つ目は、スタイルを割り当てずに名前付きのカスケードレイヤーを作成する方法です。これは下記のように単一のレイヤーとすることができます。</p> <div class="code-example"><div class="example-header"><span class="language-name">css</span></div><pre class="brush: css notranslate"><code>@layer utilities; </code></pre></div> <p>次のようにして複数のレイヤーを一度に定義することもできます。</p> <div class="code-example"><div class="example-header"><span class="language-name">css</span></div><pre class="brush: css notranslate"><code>@layer theme, layout, utilities; </code></pre></div> <p>これは、レイヤーを宣言する最初の順序が、どのレイヤーが優先されるかを示すので便利です。宣言の場合と同様に、複数のレイヤーで宣言が見つかった場合は、最後にリストアップされたレイヤーが優先されます。したがって、先ほどの例では、<code>theme</code> と <code>utilities</code> で競合するルールがあった場合、 <code>utilities</code> にあるルールが優先的に適用されるでしょう。</p> <p><code>utilities</code> のルールの方が <code>theme</code> ルールよりも詳細度が低くても適用されます。これは、レイヤーの順序が決まれば、詳細度や見た目の順序は無視されるからです。これは、セレクターが競合するルールを上書きするのに十分な高い詳細度を持つことを保証する必要がなく、後のレイヤーに表示されることだけを保証すればよいため、よりシンプルな CSS セレクターを作成することが可能になるのです。</p> <div class="notecard note"> <p><strong>メモ:</strong> レイヤー名を宣言して順番を決めたら、名前を宣言し直してレイヤーに CSS ルールを追加してください。すると、スタイルがレイヤーに追加され、レイヤーの順序は変更されません。</p> </div> <p>3 つ目は、次のように名前のないカスケードレイヤーを作成する方法です。</p> <div class="code-example"><div class="example-header"><span class="language-name">css</span></div><pre class="brush: css notranslate"><code>@layer { p { margin-block: 1rem; } } </code></pre></div> <p>これは無名カスケードレイヤーを作成します。このレイヤーは名前付きレイヤーと同じように機能しますが、後でルールを割り当てることはできません。無名レイヤーの優先順位は、名前付きまたは無名のレイヤーが宣言された順番であり、レイヤーの外側で宣言されたスタイル設定よりも下になります。</p> <p>カスケードレイヤーを作成するもう一つの方法は、 <a href="/ja/docs/Web/CSS/@import"><code>@import</code></a> を使用することです。この場合、ルールはインポートされたスタイルシートの中にあることになります。 <code>@import</code> アットルールは、 <code>@charset</code> ルールと <code>@layer</code> ルールを除く、他のすべての種類のルールに先立って入力しなければならないことを覚えておいてください。</p> <div class="code-example"><div class="example-header"><span class="language-name">css</span></div><pre class="brush: css notranslate"><code>@import "theme.css" layer(utilities);

アットルールは 3 つの方法のいずれかでカスケードレイヤーを作成するために使用します。</p>\n<p>最初の方法は、次のようにして名前付きカスケードレイヤーを作成し、 CSS ルールをその中に入れることです。</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">css</span></div><pre class=\"brush: css notranslate\"><code>@layer utilities {\n .padding-sm {\n padding: 0.5rem;\n }\n\n .padding-lg {\n padding: 0.8rem;\n }\n}\n</code></pre></div>\n<p>2 つ目は、スタイルを割り当てずに名前付きのカスケードレイヤーを作成する方法です。これは下記のように単一のレイヤーとすることができます。</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">css</span></div><pre class=\"brush: css notranslate\"><code>@layer utilities;\n</code></pre></div>\n<p>次のようにして複数のレイヤーを一度に定義することもできます。</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">css</span></div><pre class=\"brush: css notranslate\"><code>@layer theme, layout, utilities;\n</code></pre></div>\n<p>これは、レイヤーを宣言する最初の順序が、どのレイヤーが優先されるかを示すので便利です。宣言の場合と同様に、複数のレイヤーで宣言が見つかった場合は、最後にリストアップされたレイヤーが優先されます。したがって、先ほどの例では、<code>theme</code> と <code>utilities</code> で競合するルールがあった場合、 <code>utilities</code> にあるルールが優先的に適用されるでしょう。</p>\n<p><code>utilities</code> のルールの方が <code>theme</code> ルールよりも詳細度が低くても適用されます。これは、レイヤーの順序が決まれば、詳細度や見た目の順序は無視されるからです。これは、セレクターが競合するルールを上書きするのに十分な高い詳細度を持つことを保証する必要がなく、後のレイヤーに表示されることだけを保証すればよいため、よりシンプルな CSS セレクターを作成することが可能になるのです。</p>\n<div class=\"notecard note\">\n <p><strong>メモ:</strong> レイヤー名を宣言して順番を決めたら、名前を宣言し直してレイヤーに CSS ルールを追加してください。すると、スタイルがレイヤーに追加され、レイヤーの順序は変更されません。</p>\n</div>\n<p>3 つ目は、次のように名前のないカスケードレイヤーを作成する方法です。</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">css</span></div><pre class=\"brush: css notranslate\"><code>@layer {\n p {\n margin-block: 1rem;\n }\n}\n</code></pre></div>\n<p>これは無名カスケードレイヤーを作成します。このレイヤーは名前付きレイヤーと同じように機能しますが、後でルールを割り当てることはできません。無名レイヤーの優先順位は、名前付きまたは無名のレイヤーが宣言された順番であり、レイヤーの外側で宣言されたスタイル設定よりも下になります。</p>\n<p>カスケードレイヤーを作成するもう一つの方法は、 <a href=\"/ja/docs/Web/CSS/@import\"><code>@import</code></a> を使用することです。この場合、ルールはインポートされたスタイルシートの中にあることになります。 <code>@import</code> アットルールは、 <code>@charset</code> ルールと <code>@layer</code>
