# [[HOWTO CSS Fading Buttons]]

## 🎯 한 줄 통찰 (One-line insight)
Like `[[HOWTO CSS Animate Buttons]]`, this page's actual `transition`/`opacity` CSS for its three named effects (fade in, fade out, fade background) was not retrievable through text extraction — only the effect labels were captured, so this entry records the page's scope honestly rather than fabricating plausible-but-unverified `transition: opacity` values. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Three named fade effects**: fade in on hover, fade out on hover, fade background on hover. [S1]
- Specific implementation (which property transitions, duration, easing) could not be confirmed from the extracted text and is NOT included here to avoid fabrication. [S1]

## 📖 세부 내용 (Details)
- Only the three effect labels and "Try it Yourself »" markers were extracted; the live CSS lives in embedded iframe examples 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:** 0.50
- **중복 검사 결과:** 신규 생성 (New discovery) — 콘텐츠 불완전, 재검증 필요.
