+# [[HOWTO CSS Center Website]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+`margin: auto` only centers a block horizontally if the element has an EXPLICIT width (here via `max-width`) — an unconstrained block always stretches to fill its parent, leaving no leftover space for the browser to distribute as equal left/right margins, which is the entire reason this recipe pairs `max-width: 500px` with `margin: auto` rather than using either alone; this is the simplest of all the centering recipes in this cookbook because it needs neither `position`, `transform`, nor Flexbox — just a width constraint plus auto margins. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`margin: auto` requires a constrained width** — auto margins only distribute leftover horizontal space; a full-width block has none to distribute. [S1]
+- **`max-width` instead of `width`** — allows the content wrapper to shrink on narrow viewports (spanning the full page below the breakpoint) while capping its width on wide screens. [S1]
+- **No positioning/transform/flexbox needed** — the simplest technique in this cookbook's centering family, applicable to whole-page content wrappers rather than individual elements. [S1]
+
+## 📖 세부 내용 (Details)
+- `.content { max-width: 500px; margin: auto; }` applied to a wrapper `<div>` directly inside `<body>`. [S1]
+- Below 500px viewport width, the content spans the full page (since `max-width` stops constraining once the viewport is narrower than it). [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+없음 — 신규 레시피, 기존 문서와 모순되는 내용 없음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+페이지 콘텐츠를 500px 폭으로 제한하고 margin:auto로 가로 중앙 정렬해, 500px보다 좁은 화면에서는 전체 폭을 차지하게 만드는 예제가 원문에서 직접 제시됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Centering a whole page's content with max-width + margin:auto (CSS):
+```css
+.content {
+  max-width: 500px;
+  margin: auto;
+}
+```
