Scoped Styles Simplified: CSS @scope in Action
CODE PREVIEW
P
Prompt
Create a demo showing CSS @scope for component style isolation. Use a card component with nested elements (header, content, footer). The same card class should look different when placed inside a 'featured' section vs a 'sidebar' section, using @scope to limit styles.
CSS @scope を使うと、特定のDOMサブツリーにのみスタイルを制限でき、複雑な命名規則や子要素への追加クラスが不要になります。このデモでは、単一の .card コンポーネントが配置されたセクションに応じて見た目を変えます — すべてクリーンなスコープCSSで実現します。
Prompt Overview
CSS @scope lets you limit styles to specific DOM subtrees without relying on complex naming conventions or extra classes on every child. This demo shows a single .card component that adapts its appearance based on the section it lives in — all with clean, scoped CSS.
