# [[HOWTO CSS Browser Window]]

## 🎯 한 줄 통찰 (One-line insight)
This recipe's actual HTML/CSS code was not retrievable through text extraction (the page embeds its live example in an interactive iframe rather than printable markup), so this entry records only what the page's title and label confirm — a "Browser Window" CSS mockup — without fabricating specific code that couldn't be verified from the source. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Browser window mockup** — a CSS-only decorative frame styled to resemble a browser chrome (title bar, controls, content area), commonly used to showcase screenshots/demos within a page. [S1]
- Specific implementation details (colors, dot styling, bar height) could not be confirmed from the extracted text and are NOT included here to avoid fabrication. [S1]

## 📖 세부 내용 (Details)
- Only "Browser Window" (page title) and a "Try it Yourself »" label were extracted; the actual code block lives in an embedded iframe example the extractor does not capture. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
없음 — 검증 불가로 인해 비교할 세부 내용이 부족함.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 코드 예제가 텍스트로 추출되지 않았습니다. [S1]

## 💻 코드 패턴 (Code patterns)
추출되지 않음 — 원문의 라이브 코드 예제가 iframe에 있어 텍스트로 캡처되지 않았습니다. 재방문 시 브라우저 스크린샷 또는 별도 렌더링 도구로 재확인 필요.

## ✅ 검증 상태 및 신뢰도
- **상태:** draft
- **검증 단계:** unverified
- **출처 신뢰도:** B (W3Schools — widely used educational reference)
- **신뢰 점수:** 0.55
- **중복 검사 결과:** 신규 생성 (New discovery) — 콘텐츠 불완전, 재검증 필요.
