**
スタイルシート
**
(stylesheet) は、レイアウトやウェブページまたは文書のデザインを制御する CSS ルールの集合です。
*
内部
*
スタイルシートは、ウェブ文書の {{htmlelement("head")}} 内の {{htmlelement("style")}} 要素内に置かれ、
*
外部
*
スタイルシートは独立した
`
.css
`
ファイルの中に置かれ、文書ヘッダーの {{htmlelement("link")}} 内で参照することにより文書に適用されます。
外部スタイルシートは各ページに繰り返し CSS を適用するのではなく、一箇所から複数のページのスタイル設定を制御することができるため、一般的に好ましいとされています。
