+# [[HOWTO CSS Notification Button]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+The count badge is positioned with NEGATIVE offsets (`top: -10px; right: -10px;`) rather than the usual `0`/positive values seen in other absolute-positioning recipes — this deliberately pushes the badge PARTLY OUTSIDE the parent button's boundary box, creating the familiar "peeking over the corner" notification-count look, which only works because `.notification { position: relative; }` gives the badge a positioning anchor to escape from in the first place. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`position: relative` on the button** — establishes the anchor for the badge's absolute positioning, same relative/absolute pairing seen throughout this cookbook. [S1]
+- **Negative `top`/`right` offsets** — `top: -10px; right: -10px;` deliberately pushes the badge outside the button's own box, rather than flush against an inner edge. [S1]
+- **`border-radius: 50%` badge** — combined with roughly-equal padding to render as a circle around the count number. [S1]
+
+## 📖 세부 내용 (Details)
+- `.notification { background-color: #555; position: relative; display: inline-block; } .notification .badge { position: absolute; top: -10px; right: -10px; border-radius: 50%; background: red; color: white; }`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+없음 — 신규 레시피, 기존 문서와 모순되는 내용 없음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+"Inbox" 버튼 오른쪽 상단 모서리에 빨간 원형 배지로 "3"을 표시하는 예제가 원문에서 직접 제시됨. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Notification badge escaping the button's own box via negative offsets (CSS):
+```css
+.notification { position: relative; display: inline-block; }
+.notification .badge {
+  position: absolute;
+  top: -10px; right: -10px; /* negative -- pushes outside the button */
+  border-radius: 50%;
+  background: red;
+  color: white;
+}
+```
