+# [[HOWTO CSS Sticky Element]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+`position: sticky` is a HYBRID of the two positioning models this cookbook has already covered separately — it behaves like `position: relative` (occupying its normal place in the document flow) until the scroll position reaches the specified offset (`top: 0`), at which point it switches to behave like `position: fixed` (pinned to the viewport) — meaning it's not a third independent positioning scheme but a scroll-triggered TOGGLE between the two schemes already used in `[[HOWTO CSS Fixed Menu]]` and ordinary flow layout. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`position: sticky`** — toggles between `relative` and `fixed` behavior depending on scroll position. [S1]
+- **Requires an offset property** — at least one of `top`, `right`, `bottom`, or `left` MUST be specified, or sticky positioning does nothing. [S1]
+- **Browser support caveat** — explicitly noted to NOT work in Internet Explorer or Edge 15 and earlier. [S1]
+
+## 📖 세부 내용 (Details)
+- Minimal example: `div.sticky { position: sticky; top: 0; }`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **relative와 fixed 사이를 스크롤에 따라 토글하는 하이브리드**: `[[HOWTO CSS Fixed Menu]]`에서 확인된 순수 `position: fixed`와 달리, sticky는 스크롤 위치가 지정된 오프셋에 도달하기 전에는 일반 흐름(relative)을 따르다가 그 지점부터 fixed처럼 고정된다는 점이 두 방식의 결합으로 확인됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — top:0 오프셋을 지정한 최소 sticky 예제가 원문에서 제시됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Sticky positioning — toggles between relative and fixed on scroll (CSS):
+```css
+div.sticky {
+  position: sticky;
+  top: 0; /* at least one offset is required */
+}
+```
